Description

Technical Field

[0001] The embodiments of the present application relate to the field of computer technology, and in particular to a load control method, device, medium and electronic device for a subnet manager. Background Art

[0002] IB subnet technology has been increasingly widely used in the field of supercomputer clusters. The performance of network clusters using IB subnet technology has received increasing attention. A network cluster includes a subnet manager, a switch, a storage cluster node, and a computing node. The subnet manager controls the communication between the computing node and the storage cluster node via the switch. The subnet manager includes a master service node and a slave service node in the master-slave mode. In such a large-scale cluster based on an IB network, if one or more switches fail and the master-slave switch of the subnet manager occurs at the same time, the network connection between the computing node and the storage cluster node is disconnected. In order to provide services as soon as possible after the network is restored, each node starts to perform detection operations, such as ICMP detection. Due to the master-slave switch of the subnet manager, the path information cache is invalid. The IPoIB (Internet Protocol over IB, running the IP protocol on the IB network) driver of each storage cluster node in the network cluster will send a PathRecord request to the subnet manager to query the path information.

[0003] Taking two IB subnets as an example, during ICMP detection, if 2000+ computing nodes send ICMP detection packets to 200 storage nodes, each link (each computing node corresponds to 2 IP addresses stored, a total of 2 links) once per minute, the detection frequency is about 2000*200*2, about 13,000 times per second. For each ICMP detection, in the event of a network failure, the path query will be retried 10 times, then the path query is about 130K / s. If it is a larger-scale storage cluster, more nodes will be affected, and the instantaneous request volume will be even greater. This high-frequency ICMP message detection increases the CPU load of the subnet manager, which may cause the subnet manager process to overload or freeze, thereby paralyzing the entire network system.

[0004] The existing IB subnet management technology cannot automatically control the load of the subnet manager, and the subnet manager itself does not have a mechanism to limit this high load. When the above scenario occurs, the entire network system is paralyzed, and the storage system's external services are interrupted, which will seriously affect the stability of the storage system. The current recovery method is to manually reduce the instantaneous load of the subnet manager by restarting the computing nodes in batches, so that the subnet manager can provide services normally and ensure that the cluster network returns to normal. The operating efficiency of the subnet manager of the network cluster is low. Therefore, how to improve the operating efficiency of the subnet manager of the network cluster is of great practical significance. Summary of the invention

[0005] The embodiments of the present application provide a load control method, device, medium and electronic device for a subnet manager, which can improve the operating efficiency of the subnet manager of a network cluster.

[0020] If the result of the judgment is that the authorization queue is full, the first computing node is refused to be added to the authorization queue, and the authorization blocking time of the first computing node is set; the authorization blocking time is used to prohibit the first computing node from sending a detection request again before the authorization organization time is reached.

[0067] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0068] It should be noted that the terms "including" and "having" and their variations involved in the documents of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0069] The following are explanations of some of the terms that appear in the text:

[0070] (1) Infiniband (IB): Infiniband is an open standard network interconnection technology with high bandwidth, low latency and high reliability. This technology is defined by IBTA (InfiniBand Trade Association) and has been widely used in the field of supercomputer clusters.

[0071] (2) Open Subnet Manager (opensm): The subnet manager is used for configuration and management such as IB network discovery and maintenance.

[0072] (3) Stor Master: Stor Master refers to the main service node of the storage cluster; it can also be regarded as the main service for load monitoring and control, running on the storage cluster node. Stor Master is responsible for collecting, recording and analyzing the load information reported by Stor SM Agent, and making detection actions based on the load information.

[0073] (4) Stor Master backup: Stor Master backup refers to the storage cluster's main service backup node; it can also be seen as a load monitoring and control main backup service, running on the storage cluster node. When the main service node Stor Master fails, it automatically switches to the main service backup node Stor Master backup to provide services. In some embodiments, when the Stor Master service fails, the remaining cluster nodes Stor Master backup will elect a node's StorMaster backup to run as the Stor Master.

[0074] (5) Stor Client Agent: Stor Client Agent is a storage computing node agent service. It is an agent service running on the storage computing node (client node) and is used to execute instructions issued by the Stor Master, report client information and requests, etc.

[0075] (6) Stor SM Agent: Stor SM Agent refers to the agent service running on the subnet manager (including OpenSM Master and OpenSM Slave). Stor SM Agent can be regarded as the IB subnet management node agent service, which is responsible for monitoring and reporting the OpenSM load to the Stor Master. The OpenSM Master and the corresponding OpenSM Slave constitute a service group; a service group is only responsible for monitoring and reporting the load of an IB subnet.

[0076] (7) ICMP (Internet Control Message Protocol): ICMP is a sub-protocol of the TCP / IP protocol suite, used to transmit control messages between IP hosts and routers.

[0077] IB subnet technology has been increasingly widely used in the field of supercomputer clusters. The performance of network clusters using IB subnet technology has received increasing attention. A network cluster includes a subnet manager, a switch, a storage cluster node, and a computing node. The subnet manager controls the communication between the computing node and the storage cluster node via the switch. The subnet manager includes a master service node and a slave service node in the master-slave mode. In such a large-scale cluster based on an IB network, if one or more switches fail and the master-slave switch of the subnet manager occurs at the same time, the network connection between the computing node and the storage cluster node is disconnected. In order to provide services as soon as possible after the network is restored, each node starts to perform detection operations, such as ICMP detection. Due to the master-slave switch of the subnet manager, the path information cache is invalid. The IPoIB (Internet Protocol over IB, running the IP protocol on the IB network) driver of each storage cluster node in the network cluster will send a PathRecord request to the subnet manager to query the path information.

[0078] Taking two IB subnets as an example, during ICMP detection, if 2000+ computing nodes send ICMP detection packets to 200 storage nodes, each link (each computing node corresponds to 2 IP addresses stored, a total of 2 links) once per minute, the detection frequency is about 2000*200*2, about 13,000 times per second. For each ICMP detection, in the event of a network failure, the path query will be retried 10 times, then the path query is about 130K / s. If it is a larger-scale storage cluster, more nodes will be affected, and the instantaneous request volume will be even greater. This high-frequency ICMP message detection increases the CPU load of the subnet manager, which may cause the subnet manager process to overload or freeze, thereby paralyzing the entire network system.

[0079] The existing IB subnet management technology cannot automatically control the load of the subnet manager, and the subnet manager itself does not have a mechanism to limit this high load. When the above scenario occurs, the entire network system is paralyzed, and the storage system's external services are interrupted, which will seriously affect the stability of the storage system. The current recovery method is to manually reduce the instantaneous load of the subnet manager by restarting the computing nodes in batches, so that the subnet manager can provide services normally and ensure that the cluster network returns to normal. The operating efficiency of the subnet manager of the network cluster is low. Therefore, how to improve the operating efficiency of the subnet manager of the network cluster is of great practical significance.

[0080] To solve the existing technical problems, the embodiments of the present application provide a load control method, device, medium and electronic device for a subnet manager, which are applied to a storage cluster node of a network cluster based on an infinite bandwidth network; the network cluster includes a subnet manager, a storage cluster node and a computing node; the method includes: generating load record information of the subnet manager according to CPU load information; the load record information includes the received CPU load information of the subnet manager; the CPU load information includes the first CPU load information periodically sent by the subnet manager to the storage cluster node; determining the target operation mode of the subnet manager according to the load record information and a preset load threshold; and sending detection management information to the computing node according to the target operation mode, so that the computing node limits the detection operation on the subnet manager according to the detection management information. The method generates load record information by storing the CPU load information of the subnet manager received by the cluster node; determines the target operation mode of the subnet manager according to the load record information and a preset load threshold; sends detection management information to the computing node according to the target operation mode, so that the computing node limits the detection operation for the subnet manager according to the detection management information, and provides a load control mechanism for the subnet manager of a network cluster, which can efficiently adjust the CPU load of the subnet manager, reduce the high load of the CPU of the subnet manager, and improve the operation efficiency of the subnet manager of the network cluster.

[0081] In order to make the invention purpose, technical scheme and advantages of the embodiments of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0082] The technical solution provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0083] The load control method of the subnet manager provided in the embodiment of the present application can be applied to a server or a terminal device. The following embodiments of the present application are described by taking the load control method of the subnet manager applied to a terminal device as an example.

[0084] The present application embodiment provides a load control method for a subnet manager, which is applied to a storage cluster node of a network cluster based on an infinite bandwidth network; the network cluster includes a subnet manager, a storage cluster node and a computing node; Figure 1 As shown, the following steps are included:

[0085] Step S101: Generate load record information of the subnet manager according to CPU load information.

[0086] The load record information includes the received CPU load information of the subnet manager; the CPU load information is sent by the subnet manager to the storage cluster node.

[0087] In specific implementation, the storage cluster node generates the load record information of the subnet manager according to the CPU load information; the load record information includes the received CPU load information of the subnet manager; the CPU load information is sent by the subnet manager to the storage cluster node.

[0088] In some embodiments of the present application, the CPU load information includes first CPU load information periodically sent by the subnet manager to the storage cluster node.

[0090] In some optional embodiments, the CPU load information further includes: second CPU load information of the subnet manager fed back to the storage cluster node when the subnet manager receives a load query request sent by the storage cluster node.

[0091] In some embodiments of the present application, if the Stor Master of a storage cluster node does not receive a report from the Stor SMAgent for a long time, the Stor Master proactively queries the Stor SM Agent for the CPU load of the opensm process of the node where it is located.

[0092] In some embodiments of the present application, in order to ensure smooth mode switching, during the target operation mode of the subnet manager, the load record information is determined by using a sampling average value combined with a second-order recursive filter.

[0093] A typical second-order recursive filter can be expressed as:

[0094] F i =α×L i +β×F i-1 +γ×F i-2 ,

[0095] in:

[0096] F i is the estimated value after the i-th filtering;

[0097] L i is the load measurement value at the ith time;

[0098] F i-1 and F i-2 are the first two filtering estimation values ​​respectively;

[0099] α, β, and γ are filter coefficients, and their sum is 1. If you need the output to quickly reflect the most recent changes, you can increase α. If you want the output to change smoothly without rapid fluctuations, you can increase β and γ.

[0100] In some embodiments of the present application, the load record information includes CPU load information and filter parameters, wherein the filter parameters are determined by using a sampling average value combined with a second-order recursive filter; and the filter parameters represent the estimated value after filtering.

[0101] In some embodiments of the present application, the sampled average value may be the load measurement value of the aforementioned embodiment.

[0102] In some embodiments, the filter parameters are obtained as follows:

[0103] The average value is calculated for every N sample values, which is used as the L of the second-order filtering algorithm. i ; The value of N can be adjusted by configuring parameters; α determines the weight of this sampling, and β and γ determine the weight of the historical estimation value;

[0104] The estimated value F is calculated based on the previous two estimated values. i , as the filter parameters.

[0105] In some embodiments of the present application, the sampling value is taken from CPU load information.

[0106] Step S102: determining a target operation mode of the subnet manager according to the load record information and a preset load threshold.

[0107] During specific implementation, the storage cluster node determines the target operation mode of the subnet manager according to the load record information and the preset load threshold.

[0108] In some embodiments of the present application, Stor Master decides that the corresponding IB subnet runs different working modes according to the changes in opensm load, and notifies all Stor Client Agent nodes.

[0109] In some embodiments of the present application, a preset working mode is set according to whether to perform a detection operation corresponding to the IB subnet; the working modes include: normal mode and silent mode. In the normal mode, the computing nodes (external clients) in the characterization system can send detection operations corresponding to the IB subnet at any time according to their own needs, such as sending ICMP messages; the silent mode indicates that if the computing node needs to send ICMP messages to the corresponding IB subnet to detect the link status, it needs to send a message to the Stor Master to apply for detection operation authorization.

[0110] In some embodiments of the present application, in silent mode, if the computing node is authorized, the corresponding IB subnet can send a message to apply for detection operation authorization as needed within the timeout period; if the computing node's application for authorization is rejected or the authorization has expired (exceeded the validity period), the corresponding IB subnet cannot send a message to apply for detection operation authorization.

[0111] In some embodiments of the present application, if the computing node's application for authorization is rejected or the authorization has expired (exceeded the validity period), the computing node needs to send a message to the Stor Master again to apply for authorization after a period of time.

[0112] In some embodiments of the present application, the Stor SM Agent of the subnet manager monitors the CPU utilization of the opensm process of the node, and periodically reports the average load and role information over a period of time to the Stor Master of the cluster node; after receiving the load information, the Stor Master records the load information and decides whether to switch the operating mode of the corresponding IB subnet based on the reported load records; if the Stor SM Agent does not report for a long time, the Stor Master actively queries the Stor SM Agent for the CPU load information of the opensm process of the corresponding node.

[0113] In some embodiments, the decision process for determining the target operating mode of the subnet manager includes:

[0114] The estimated value F is calculated based on the previous two estimated values. i If the actual CPU load is significantly different from the actual CPU load, indicating large fluctuations, wait for several reporting cycles before switching the working mode.

[0115] When the number of times the load is continuously higher or lower than the load threshold reaches the control cycle threshold, the storage cluster node determines whether to allow the switching of the working mode; wherein the control cycle threshold is determined based on the reporting cycle and the expected system fault recovery time; the control cycle threshold can be a configuration parameter.

[0116] In some embodiments, when determining whether to allow switching of the working mode, if the load is higher than a threshold, the Stor Master determines to set the corresponding IB subnet to silent mode; if the load is lower than the threshold, the Stor Master determines to set the corresponding IB subnet to normal mode.

[0117] In some optional embodiments, the target operation mode includes a normal mode and a silent mode; in the above step S102, the process of determining the target operation mode of the subnet manager according to the load record information and the preset load threshold is as follows: Figure 2 As shown, this can be achieved by following the steps below:

[0118] Step S201: judging whether the CPU load information of the control cycle threshold as of the current moment is less than the load threshold according to the load record information and the preset load threshold.

[0119] Step S202: If it is monitored that the CPU load information of the control cycle threshold as of the current moment is all less than the load threshold, the target operation mode of the subnet manager is the normal mode.

[0120] Step S203: If it is monitored that the CPU load information of the control cycle threshold as of the current moment is greater than the load threshold, the target operation mode of the subnet manager is the silent mode.

[0121] The method of this embodiment, the target operation mode, includes normal mode and silent mode; according to the load record information and the preset load threshold, the target operation mode of the subnet manager is determined, including: according to the load record information and the preset load threshold, judging whether the control cycle threshold CPU load information as of the current moment is less than the load threshold; if it is monitored that the control cycle threshold CPU load information as of the current moment is less than the load threshold, then the target operation mode of the subnet manager is normal mode; if it is monitored that the control cycle threshold CPU load information as of the current moment is greater than the load threshold, then the target operation mode of the subnet manager is silent mode, and the target operation mode can be accurately set to normal mode and silent mode, the normal mode characterization allows detection operations on the subnet manager, and the silent mode characterization does not allow detection operations on the subnet manager, so as to further achieve more accurate adjustment of the CPU load of the subnet manager based on the normal mode and the silent mode, reduce the high load of the CPU of the subnet manager, and improve the operation efficiency of the subnet manager of the network cluster.

[0122] Step S103: sending detection management information to the computing node according to the target operation mode, so that the computing node limits the detection operation for the subnet manager according to the detection management information.

[0123] In some embodiments of the present application, when it is determined that the switching of the working mode is allowed, if the load is higher than the threshold, the Stor Master notifies all computing nodes corresponding to the IB subnet to enter silent mode by sending detection management information.

[0124] For example, if the load of either Opensm Master or Opensm Slave exceeds the threshold, Stor Master notifies all computing nodes corresponding to the IB subnet to enter silent mode.

[0125] After receiving the message, the Stor Client Agent calls the tool to shut down the detection of the IB subnet corresponding to this node. If the notification fails, the Stor Master will retry multiple times. After the shutdown is successful, it will record the IB subnet detection status of each computing node.

[0126] In some optional embodiments, according to the target operation mode, sending the detection management information to the computing node so that the computing node limits the detection operation for the subnet manager according to the detection management information includes:

[0127] If the target operation mode is the normal mode, sending the first detection management information to the computing node, so that the computing node is allowed to perform the detection operation for the subnet manager according to the first detection management information;

[0128] If the target operation mode is the silent mode, the second detection management information is sent to the computing node, so that the computing node prohibits the execution of the detection operation for the subnet manager according to the second detection management information.

[0129] The method of this embodiment can further achieve more efficient adjustment of the CPU load of the subnet manager based on the normal mode and the silent mode, reduce the high load of the CPU of the subnet manager, and improve the operating efficiency of the subnet manager of the network cluster.

[0130] In some optional embodiments, the load control method of the subnet manager, such as Figure 3 As shown, the following steps are also included:

[0131] Step S301: If the target operation mode is the silent mode and a detection request sent by the first computing node is received, it is determined whether the authorization queue is full.

[0132] In some embodiments of the present application, the Stor Master of the storage cluster node maintains an authorization queue, the length of which can be adjusted by parameters, and upon receiving an application, it first checks whether the authorization queue is full.

[0133] In specific implementation, when the IB subnet corresponding to the first computing node is in silent mode and there is a detection demand, the Stor Client Agent of the first computing node will initiate a detection request for the corresponding IB subnet. When the storage cluster node receives the detection request sent by the first computing node, it determines whether the authorization queue is full.

[0134] Step S302, if the result of the judgment is that the authorization queue is not full, the first computing node is added to the authorization queue, and the authorization control time of the first computing node is set; the authorization control time is used to remove the first computing node from the authorization queue after the authorization control time is reached to terminate the authorization of the first computing node.

[0135] In specific implementation, if the authorization queue is not full, the corresponding computing node will be added to the authorization queue and the authorization time will be recorded. After the Stor Client Agent obtains the authorization, it will start the detection operation of the corresponding IB subnet. If the corresponding IB subnet connection is restored, the Stor Master will be notified to release the authorization. The Stor Master will remove the node from the authorization queue and record its connection recovery status. If the authorization is not released within the timeout period (which can be adjusted by parameters), the Stor Master will also remove the node from the authorization queue, and the Stor Client Agent will automatically close the detection operation of the corresponding computing node IB subnet after the timeout period.

[0136] Step S303, if the result of the judgment is that the authorization queue is full, the first computing node is refused to be added to the authorization queue, and the authorization blocking time of the first computing node is set; the authorization blocking time is used to prohibit the first computing node from sending a detection request again before the authorization organization time is reached.

[0137] In specific implementation, if the authorization queue is full, authorization will be rejected and the Stor Client Agent will wait for a period of time t before reapplying for authorization; t increases randomly with the number of failed authorization applications to prevent frequent requests to the Stor Master from causing high load on the Stor Master.

[0138] In some embodiments of the present application, it also includes: the storage cluster node records the recovery status of the IB subnets corresponding to all computing nodes; when the recorded recovery status of the IB subnets corresponding to all computing nodes is recovery, and the load is lower than the threshold for several consecutive times, the storage cluster node batch notifies the IB subnets corresponding to all computing nodes to recover from silent mode to normal mode; after receiving the request, the computing node will turn on the detection operation of the IB subnet corresponding to the node and return the result. After all computing nodes respond, it indicates that the corresponding IB subnet has successfully recovered to normal mode; if during the recovery process of the IB subnet from silent mode to normal mode, it is monitored that the load exceeds the threshold again, the target operation mode of the subnet manager is re-determined to be silent mode.

[0139] Exemplarily, when the recovery status of the IB subnets corresponding to all computing nodes recorded by Stor Master is recovery, and the load is lower than the threshold for several consecutive times (wherein the loads of Opensm Master and Opensm Slave are both lower than the threshold), Stor Master will batch notify all Stor Client Agents to restore the corresponding IB subnets from silent mode to normal mode. After receiving the request, Stor Client Agent will turn on the detection operation of the IB subnet corresponding to this node and return the result. After all computing nodes respond, it means that the corresponding IB subnet has successfully recovered to normal mode. If the load exceeds the threshold again during the recovery process, it will re-enter silent mode.

[0140] In some embodiments of the present application, the detection operation is specifically ICMP detection.

[0141] In the method of this embodiment, a control mechanism for computing nodes to initiate detection requests in silent mode is provided, which can further achieve more fine-grained adjustment of the CPU load of the subnet manager based on normal mode and silent mode, reduce the high load of the CPU of the subnet manager, while taking into account the performance stability of the network cluster, and improving the operating efficiency of the subnet manager of the network cluster.

[0142] The present application embodiment provides a load control method for a subnet manager, which is applied to a subnet manager of a network cluster based on an infinite bandwidth network; the network cluster includes a subnet manager, a storage cluster node and a computing node; Figure 4 As shown, the following steps are included:

[0143] Step S401, monitoring the CPU load information of the subnet manager.

[0146] During specific implementation, the subnet manager sends the CPU load information of the subnet manager to the storage cluster node, so that the storage cluster node generates the load record information of the subnet manager based on the CPU load information, and determines the target operation mode of the subnet manager based on the load record information of the subnet manager and a preset load threshold, and sends detection management information to the computing node according to the target operation mode; the detection management information is used by the computing node to limit the detection operation on the subnet manager; the load record information includes the received CPU load information of the subnet manager.

[0147] In some optional embodiments, the CPU load information includes first CPU load information periodically sent by the subnet manager to the storage cluster node.

[0148] In some optional embodiments, the CPU load information further includes second CPU load information; the second CPU load information is fed back to the storage cluster node by the subnet manager in response to receiving a load query request sent by the storage cluster node.

[0149] The method of this embodiment monitors the CPU load information of the subnet manager through the subnet manager; sends the CPU load information of the subnet manager to the storage cluster node, so that the storage cluster node generates the load record information of the subnet manager according to the CPU load information, and determines the target operation mode of the subnet manager according to the load record information of the subnet manager and a preset load threshold, and sends detection management information to the computing node according to the target operation mode; the detection management information is used for the computing node to limit the detection operation on the subnet manager, and provides a load control mechanism for the subnet manager of the network cluster, which can efficiently adjust the CPU load of the subnet manager, reduce the high load of the CPU of the subnet manager, and improve the operation efficiency of the subnet manager of the network cluster.

[0152] Step S502: If the detection management information is received, the detection operation on the subnet manager is restricted according to the received detection management information.

[0153] In some embodiments of the present application, the target operation mode includes a normal mode and a silent mode; the detection management information includes a first detection management information and a second detection management information; in step S502, according to the received detection management information, the process of limiting the detection operation for the subnet manager, such as Figure 6 As shown, this can be achieved through the following process:

[0154] Step S601: If the detection management information is the first detection management information, the detection operation for the subnet manager is allowed to be performed; the first detection management information is sent by the storage cluster node to the computing node when the target operation mode is the normal mode.

[0155] Step S602: If the detection management information is the second detection management information, the detection operation on the subnet manager is prohibited; the second detection management information is sent by the storage cluster node to the computing node when the target operation mode is the silent mode.

[0156] The method of this embodiment, by setting the target operating mode to normal mode and silent mode, the normal mode characterization allows detection operations on the subnet manager, and the silent mode characterization does not allow detection operations on the subnet manager, thereby being able to further achieve more accurate adjustment of the CPU load of the subnet manager based on the normal mode and the silent mode, reduce the high load of the CPU of the subnet manager, and improve the operating efficiency of the subnet manager of the network cluster.
