[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. 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 this application.

[0048] At present, in the application scenarios based on containerized intensive computing, there is a problem of high CPU and memory latency. Therefore, how to reduce the memory access latency of containerized intensive computing and avoid performance degradation is a problem that needs to be solved. To this end, this application provides a container creation solution that can reduce the memory access latency of containerized intensive computing, thereby avoiding performance degradation.

[0049] See also Figure 1 As shown, the embodiment of the present application discloses a container creation method, including:

[0050] Step S11: Obtain a container creation request; wherein the container creation request includes the required number of CPU cores and the required memory size for starting the container.

[0051] Step S12: Acquire the topological structure of the CPU and memory and the current resource usage information of the CPU and memory.

[0052] In a specific implementation, the step S12 may specifically include:

[0053] Step 121: for any CPU Socket, if the number of available CPU cores on any CPU die on the CPU Socket is greater than or equal to the required number of CPU cores, and the available memory of the memory closest to the CPU Socket is greater than or equal to the required memory size, then the CPU die is determined as a candidate CPU die, and the memory is determined as a candidate memory corresponding to the CPU die;

[0054] Step 122: determining a first candidate node based on the candidate CPU dies and the candidate memories corresponding to all the CPU Sockets, determining a first target node from all the first candidate nodes, and obtaining a target CPU resource and a target memory resource;

[0055] The first candidate node includes the number of CPU cores required on the same candidate CPU die and the memory resources of the required memory size in the candidate memory corresponding to the candidate CPU die. Specifically, the first candidate node also includes the CPU core, the topological structure of the memory and the location information.

[0056] For example, the required number of cores is 4, the required memory is 16G, the number of available CPU cores in CPU die1 and die3 in CPU Socket1 is equal to 4, which are core1, core2, core3, core4 in their respective dies, and the available memory of memory1 closest to Socket1 is greater than 16G, then candidate node 1 (core1, core2, core3, core4 in die1, memory1(16G)) and candidate node 2 (core1, core2, core3, core4 in die3, memory1(16G)) are listed.

[0057] In a specific implementation, the first target node can be determined from all the first candidate nodes according to the CPU die utilization rate and the memory utilization rate to obtain the target CPU resources and the target memory resources.

[0058] Specifically, the first candidate node with the highest CPU die utilization and memory utilization can be determined as the first target node. If the CPU die utilization and memory utilization are the same, they are randomly selected. In this way, the same task can be executed on the same CPU die and memory as much as possible.

[0059] That is, the present application first determines the target CPU resources and the target memory resources based on the principle of selecting a CPU core from the same CPU die and the closest memory to the CPUSocket where the current CPU die is located meeting the memory size requirement, thereby avoiding the CPU core from crossing the CPU die.

[0060] Step 123: If the number of available CPU cores on any CPU die in any CPU Socket is less than the required number of CPU cores, the number of available CPU cores in the CPU Socket is greater than or equal to the required number of CPU cores, and the available memory of the memory closest to the CPU Socket is greater than or equal to the required memory size, then the CPU Socket is determined as a candidate CPU Socket, and the memory is determined as a candidate memory corresponding to the CPU Socket;

[0061] Step 124: determining a second candidate node based on all the CPU Sockets and the candidate memories, determining a second target node from all the second candidate nodes, and obtaining a target CPU resource and a target memory resource;

[0062] The second candidate node includes the required number of CPU cores on the same candidate CPU Socket and memory resources of the required memory size in the candidate memory corresponding to the candidate CPU Socket.

[0063] In a specific implementation manner, the second candidate node with the highest CPU Socket usage rate and memory usage rate may be determined as the second target node. If the CPU Socket usage rate and the memory usage rate are the same, a random selection is performed.

[0064] That is, when the CPU core cannot be selected from the same CPU die, the target CPU resources and the target memory resources are determined based on the principle of selecting the CPU core from the same CPU Socket and the memory closest to the current CPU Socket meets the memory size requirement, thereby avoiding the CPU core from crossing the CPU Socket.

[0065] Step 125: If the number of available CPU cores in any CPU Socket is less than the required number of CPU cores, and / or the available memory of the memory closest to the CPU Socket is less than the required memory size, determine the target CPU resources and the target memory resources according to a first preset condition;

[0066] The first preset condition is that the number of CPU Sockets used is the least, and the number of available CPU cores in the CPU Socket and the available memory size of the memory closest to the CPU Socket meet a preset ratio relationship.

[0067] Specifically, the third candidate node can be determined according to the first preset condition, and then the third candidate node with the highest CPU Socket usage and memory usage can be determined as the third target node. If the CPU Socket usage and memory usage are the same, a random selection is performed. The concept of the third candidate node can refer to the first candidate node and the second candidate node mentioned above.

[0068] For example, the requested number of CPU cores is 8, the memory is 32G, the total resources of each Socket are 16Cores, 32GMemory, and the remaining resources are Socket1: 4Cores, 4G Memory; Socket2: 6Cores, 28G Memory; Socket3: 4Cores, 16G Memory; Socket4: 2Cores, 10G Memory; the preset ratio is the requested number of CPU cores: memory size is 1:4G; Socket1 does not meet the ratio, and the alternative nodes can be determined by Socket2+Socket3 and Socket2+Socket4. Because the CPU memory usage of Socket2+Socket4 is greater than that of Socket2+Socket3, the container will be scheduled to the alternative node determined based on Socket2+Socket4.

[0069] Step 126: If the target CPU resource and the target memory resource cannot be determined according to the first preset condition, determine the target CPU resource and the target memory resource according to the second preset condition;

[0070] The second preset condition is that the sum of the number of used CPU Sockets and the number of memories to be bound that are not the closest to the corresponding CPU Sockets is the smallest. If the sum is the same, then the number is determined randomly.

[0071] Step S13: Determine the target CPU resources and target memory resources required to start the container based on the container creation request using the topology structure and the resource usage information.

[0072] Step S14: Bind the container with the target CPU resources and the target memory resources and start them.

[0073] For example, see Figure 2 As shown, Figure 2A specific CPU and memory topology diagram disclosed in an embodiment of the present application. Among them, CPU Core: CPU core, the task processing unit of the CPU. CPU Die: a single CPU chip, usually each CPU Die contains multiple CPU Cores, and the CPU Dies are interconnected through an off-chip bus (Infinity Fabric), and the CPU cores on different CPU Dies cannot share the CPU cache. CPU Socket: a single CPU in a CPU slot, each CPU Socket has one or more Dies. Memory: refers to the memory installed on the physical server. Due to the server topology architecture, the delay of Socket accessing the memory closest to the non-current Socket is greater than the delay of Socket accessing the current Socket, that is, the delay of Socket1 accessing Memory2 is greater than the delay of Socket2 accessing Memory2; and because of the cache sharing mechanism in the CPU, the delay of Core data sharing in Die1 is lower than the delay of Core data sharing in Die1 and Die2. The Core communication between cross-Sockets needs to pass through Memory, and the delay will be more serious. Therefore, the aforementioned method based on the present application determines the target CPU resources and the target memory resources based on the topological structure of the CPU and memory, which can reduce the delay.

[0074] In addition, considering the SMT (Simulate MultiThreading) technology, which refers to the simultaneous execution of multiple threads on a CPU core, intensive computing tasks will be assigned to the same physical core, resulting in performance degradation when switching threads. SMT will be turned off by default during initialization, that is, before resource allocation and scheduling, SMT will be turned off, so that only physical cores will be allocated during resource allocation and scheduling.

[0075] It can be seen that the embodiment of the present application first obtains a container creation request, wherein the container creation request includes the required number of CPU cores and the required memory size for starting the container, then obtains the topological structure of the CPU and memory and the resource usage information of the current CPU and memory, and then determines the target CPU resources and target memory resources required to start the container based on the container creation request using the topological structure and the resource usage information, and finally binds the container to the target CPU resources and the target memory resources and starts it. That is, the embodiment of the present application takes into account the topological structure of the CPU and memory in the process of determining the target CPU resources and the target memory resources corresponding to the container, so that the determined target CPU resources and the target memory resources can reduce the memory access delay of containerized intensive computing, thereby avoiding performance degradation.

[0076] See also Figure 3As shown, the embodiment of the present application discloses a container creation method, including:

[0077] Step S21: Obtain a container creation request; wherein the container creation request includes the required number of CPU cores and required memory size for starting the container;

[0078] Step S22: Determine whether there is a preset resource information file locally. If not, create the resource information file and add the topological structure of the CPU and memory and the resource usage information of the current CPU and memory to the resource information file; if it exists, verify the resource usage information and update the resource usage information based on the verification result.

[0079] It should be noted that when creating the resource information file, the resource usage information added to the resource information file is that all CPUs and memories are available. Specifically, verifying the resource usage information includes: reading the resource usage information in the preset resource information file, judging whether the container previously bound to the CPU and memory exists based on the resource usage information, and if not, updating the resource usage information and marking the corresponding CPU resources and memory resources as available.

[0080] Step S23: Acquire the topological structure of the CPU and memory and the resource usage information of the current CPU and memory from the preset resource information file.

[0081] In a specific implementation, it is determined based on the resource usage information whether the current available CPU resources and available memory resources meet the requirements. If they do, step 24 is started; otherwise, information indicating insufficient resources and scheduling failure is returned.

[0082] Step S24: Determine the target CPU resources and target memory resources required to start the container based on the container creation request using the topology structure and the resource usage information;

[0083] Step S25: Bind the container to the target CPU resources and the target memory resources and start them.

[0084] If the startup is successful, the preset resource information file is updated based on the target CPU resources and the target memory resources, and the target CPU resources and the target memory resources are marked as unavailable; otherwise, failure log information is output.

[0085] Furthermore, the embodiment of the present application writes the corresponding Numa (i.e., Non Uniform Memory Access) controller, Numa scheduler, and Numa launcher based on the aforementioned method, obtains the container creation request through the Numa controller, obtains the topological structure of the CPU and memory and the resource usage information of the current CPU and memory through the Numa scheduler; based on the container creation request, determines the target CPU resources and target memory resources required to start the container using the topological structure and the resource usage information; binds the container to the target CPU resources and the target memory resources through the Numa launcher and starts it.

[0086] For example, see Figure 4 As shown, an embodiment of the present application discloses a specific flow chart of a container creation method.

[0087] 1) After receiving the container creation request, the Numa controller determines whether there is a NumaList file. If there is no NumaList file, it creates a NumaList file, turns off hyperthreading (i.e., SMT technology), and writes the CPU memory topology and whether it can be called into the file. By default, all CPUs and memories can be called. If a NumaList file exists, the CPU and memory information is checked to determine whether the container previously bound to the CPU exists, and the available CPU and memory information is updated. Finally, the startup information, including the required number of CPU cores and the required memory size for starting the container, is passed to the Numa scheduler.

[0088] 2) After receiving the startup information, the Numa scheduler queries the available resources in NumaList. If the CPU and memory resources can meet the startup requirements, the CPU resources and memory resources of the startup container are determined through the scheduling priority algorithm, that is, the method for determining the target CPU resources and target memory resources disclosed in the aforementioned embodiment, and the corresponding information is passed to the Numa launcher; if any of the CPU and memory resources cannot meet the startup requirements, the startup fails and returns insufficient resource information;

[0089] 3) After receiving the information sent by the Numa scheduler, the Numa launcher binds the container with the target CPU resources and target memory resources and starts it. If the container can be started, the successful startup information is returned to the Numa controller; if the startup fails, the log information is output.

[0090] 4) After receiving the successful startup information of the Numa launcher, the Numa controller updates the NumaList file, sets the CPU resources and memory resources used for startup to unavailable, and updates the CPU and memory information.

[0095] The container startup module 14 is used to bind the container with the target CPU resources and the target memory resources and start them.

[0096] It can be seen that the embodiment of the present application first obtains a container creation request, wherein the container creation request includes the required number of CPU cores and the required memory size for starting the container, then obtains the topological structure of the CPU and memory and the resource usage information of the current CPU and memory, and then determines the target CPU resources and target memory resources required to start the container based on the container creation request using the topological structure and the resource usage information, and finally binds the container to the target CPU resources and the target memory resources and starts it. That is, the embodiment of the present application takes into account the topological structure of the CPU and memory in the process of determining the target CPU resources and the target memory resources corresponding to the container, so that the determined target CPU resources and the target memory resources can reduce the memory access delay of containerized intensive computing, thereby avoiding performance degradation.

[0097] Among them, the resource determination module 13 is specifically used to, for any CPU Socket, if the number of available CPU cores on any CPU die on the CPU Socket is greater than or equal to the required number of CPU cores, and the available memory of the memory closest to the CPU Socket is greater than or equal to the required memory size, then the CPU die is determined as an alternative CPU die, and the memory is determined as the alternative memory corresponding to the CPU die; a first alternative node is determined based on the alternative CPU die and the alternative memory corresponding to all the CPU Sockets, and a first target node is determined from all the first alternative nodes to obtain target CPU resources and target memory resources; wherein the first alternative node includes the required number of CPU cores on the same alternative CPU die and memory resources of the required memory size in the alternative memory corresponding to the alternative CPU die.

[0099] If the number of available CPU cores in any CPU Socket is less than the required number of CPU cores, and / or the available memory of the memory closest to the CPU Socket is less than the required memory size, the target CPU resources and the target memory resources are determined according to a first preset condition; wherein the first preset condition is that the number of CPU Sockets used is the least, and the number of available CPU cores in the CPU Socket used and the available memory size of the memory closest to the CPU Socket satisfy a preset proportional relationship.

[0100] If the target CPU resources and the target memory resources cannot be determined according to the first preset condition, the target CPU resources and the target memory resources are determined according to the second preset condition; wherein the second preset condition is that the sum of the number of CPU Sockets used and the number of memories to be bound that are not closest to the corresponding CPU Socket is the smallest.

[0101] In a specific implementation, the resource determination module 13 is specifically used to determine the first target node from all the first candidate nodes according to the CPU die utilization rate and the memory utilization rate, and obtain the target CPU resources and the target memory resources.

[0102] Furthermore, when the request acquisition module 11 obtains the container creation request, it determines whether there is a preset resource information file locally. If not, it creates the resource information file and adds the topological structure of the CPU and memory and the resource usage information of the current CPU and memory to the resource information file; if it exists, it verifies the resource usage information and updates the resource usage information based on the verification result;
