Description

Technical Field

[0001] The present invention relates to the field of memory recycling, and particularly to an adaptive memory recycling control method, device, terminal and storage medium. Background Art

[0002] With the development of data centers and cloud computing services, making services efficient, stable and fast has always been the pursued goal. For different services and peak and trough situations of services, there are always differences in memory requirements. Currently, there are mainly two memory recycling paths under the Linux operating system: asynchronous recycling and direct recycling. The trigger of memory recycling is related to the memory waterline. Currently, the waterlines in the Linux system are divided into the minimum waterline (WMARK_MIN), the low waterline (WMARK_LOW), and the high waterline (WMARK_HIGH).

[0003] The existing memory recycling mechanism of the operating system is strongly related to the memory allocation process. The trigger of memory recycling starts when the memory allocation is insufficient. In this case, the trigger condition for asynchronous memory recycling is that the current available memory has dropped to the low waterline, the memory is slightly insufficient, and the asynchronous recycling thread is awakened to perform memory recycling; the trigger condition for direct recycling is that the current available memory has dropped to the minimum waterline, the system memory is severely insufficient, and the current process needs to wait for the memory release of other processes to be allocated memory, which will cause process delay and damage the isolation between processes.

[0004] Currently, some researchers monitor the state of memory pages, and at the same time add some low-speed memory devices on physical devices to migrate the cold memory pages in the system, and reserve the high-speed memory resources for the processes being allocated by the system. However, this only adds physical devices and does not optimize the mechanism from the perspective of technical control.

[0005] It can be seen that the current memory recycling mechanism is controlled by the allocation process. In this case, the utilization rate of system memory resources may usually be in a relatively high state, but at the same time, the high-utilization memory state brings some problems to various services in the application layer. For example, when the recycling efficiency is lower than the allocation efficiency, the system runs in a high-memory usage state for a long time. When there is a short-term large batch of memory usage requirements, it causes slow response of service states, process jams, etc., and even causes serious service interruptions. Therefore, in view of these problems, it is necessary to optimize the existing mechanism or create a new recycling mechanism to ensure that the system can provide a large-capacity memory reserve for services for a long time under the condition of a fixed memory capacity, reserve a buffer for sudden high-load and high-capacity needs, and ensure the stable operation of service states. Summary of the Invention

[0006] To solve the above problems, the present invention provides an adaptive memory recycling control method, apparatus, terminal and storage medium, which dynamically adjusts and controls memory recycling according to the real-time business's demand for memory resources. By monitoring the direct recycling behavior occurring in the system, asynchronous recycling is started in advance and the asynchronous recycling time is increased; by dynamically adjusting the memory waterline difference parameter, the difference between the low waterline and the high waterline is adjusted to reserve more buffer for asynchronous recycling and recycle more memory; through these two measures, the system memory recycling start point and recycling time are adjusted to give more buffer to the memory recycling behavior and avoid direct recycling triggered by a large batch of memory applications at one time.

[0016] S33, judge whether the current memory waterline difference is consistent with the found memory waterline difference adjustment parameter;

[0017] S34, if they are consistent, do nothing; if they are inconsistent, adjust the memory waterline difference according to the found memory waterline difference adjustment parameter.

[0018] Further, the memory waterline difference step adjustment parameters corresponding to the ratio of the memory consumption rate to the recycling rate configured in step S0 specifically include:

[0021] The ratio of the memory consumption rate to the recycling rate ≥ 1.2, and the memory waterline difference is 80.

[0022] Furthermore, the method further includes the following steps:

[0024] S5. If a direct recycling operation occurs, continuously execute step S3;

[0025] S6. If there is no direct recycling operation again, determine whether the ratio of the memory consumption rate to the recycling rate is less than 1, and whether the current available memory of the system has been recycled to the high waterline state;

[0026] S7. If so, put the asynchronous recycling process into sleep; otherwise, continuously execute step S3.

[0027] Furthermore, step S0 further includes: pre-configuring a preset time interval.

[0028] Furthermore, step S1 monitors whether a direct recycling operation occurs within a preset time interval, specifically including:

[0029] S11. Detect whether the direct recycling count increases within a preset time interval;

[0030] S12. If it increases, it indicates that a direct recycling operation occurs.

[0047] In order to enable those skilled in the art to better understand the solutions of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0048] The core of the present invention is to provide an adaptive memory recycling control method, which can be applied to the Linux system. An adaptive kswapd wake-up mechanism is designed. According to the count of direct recycling in the kernel under the current Linux system, the kswapd recycling thread is woken up in advance, without waiting for the available memory of the current system to drop to the low watermark before starting the process. Without affecting the memory application of the process, active memory recycling actions are carried out in advance; an adaptive watermark_scale_factor parameter adjustment mechanism is designed. By increasing the watermark_scale_factor parameter, the difference between the waterlines in the memory is controlled, and the difference between the low watermark and the high watermark is increased, reserving a larger buffer space for kswapd, so that the kswapd thread can recycle as much memory value as possible in one recycling, avoiding the situation where the speed of large batch memory applications is greater than the kswapd recycling speed in a short time, thereby avoiding triggering direct recycling.

[0049] Embodiment 1

[0050] The first embodiment of the present invention provides an adaptive memory recycling control method. Figure 1 It is a schematic diagram of the architecture principle of this method. Figure 2 It is a schematic diagram of the process principle of this method. This method specifically includes the following steps.

[0051] S1. Monitor whether a direct recycling operation occurs within a preset time interval.

[0052] S2. If a direct recycling operation occurs, start an asynchronous recycling process.

[0053] It should be noted that if a direct recycling operation does not occur, step S1 is continuously executed.

[0054] S3. In the asynchronous recycling process, adjust the memory waterline difference according to the ratio of the memory consumption rate to the recycling rate.

[0055] The larger the ratio of the memory consumption rate to the recycling rate, the larger the memory waterline difference; where the memory waterline difference refers to the difference between the high waterline and the low waterline.

[0056] Such as Figure 1 and 2 shown, create a monitoring service to monitor whether direct recycling behavior occurs in the kernel under the current system, monitor the memory recycling efficiency and the memory waterline difference in the asynchronous recycling process. If direct recycling behavior is detected within a certain time α, wake up the asynchronous recycling process and start abnormal recycling in advance, otherwise continue to monitor the direct recycling behavior. During the asynchronous recycling process, the monitoring service continues to be responsible for judging the possible changes in the memory of the current system, that is, dynamically perceiving the ratio of the memory consumption rate to the recycling rate. If the ratio of the memory consumption rate to the recycling rate is large, increase the memory waterline difference to win more time for the abnormal recycling process to recycle. If the ratio of the memory consumption rate to the recycling rate is small, reduce the memory waterline difference, reduce the running time of the asynchronous recycling process, and reduce the system resource occupancy.

[0057] Embodiment 2

[0058] Figure 3 is a schematic flowchart of an adaptive memory recycling control method provided by Embodiment 2 of the present invention. Such as Figure 3 shown, the method includes the following steps.

[0059] S0. Pre-configure the memory waterline difference step adjustment parameters corresponding to the ratio of the memory consumption rate to the recycling rate; pre-configure the preset time interval.

[0060] For example, configure the preset time interval α to be 30 seconds.

[0061] For example, configure the memory waterline difference step adjustment parameters corresponding to the ratio of the memory consumption rate to the recycling rate, specifically:

[0062] The ratio of the memory consumption rate to the recycling rate < 1, the memory waterline difference is 10;

[0063] 1 ≤ the ratio of the memory consumption rate to the recycling rate < 1.2, the memory waterline difference is 30;

[0064] The ratio of the memory consumption rate to the recycling rate ≥ 1.2, the memory waterline difference is 80.

[0065] The memory waterline difference step adjustment parameter is a multi-level configuration adjustment, which can be customized according to the service status, adjusting the number of parameter steps, as well as the trigger conditions and control strengths in each step.

[0066] S1, monitor whether a direct recycling operation occurs within a preset time interval.

[0067] Specifically, it is judged whether a direct recycling operation occurs by monitoring the change of the direct recycling count.

[0068] The monitoring service monitors the change of the direct recycling count. If the direct recycling count changes within the preset time interval of 30 seconds (in one system operation state, the value of the direct recycling count can only increase, so monitoring the change state is to monitor the increase of the direct recycling count), it means that a direct recycling operation occurs. At this time, the asynchronous recycling process is awakened for memory recycling.

[0069] S2, if a direct recycling operation occurs, start the asynchronous recycling process; otherwise, continuously execute step S1.

[0070] If a direct recycling operation occurs, it indicates that the system memory has not reached a serious shortage, and the asynchronous recycling is started in advance.

[0071] S3, in the asynchronous recycling process, adjust the memory waterline difference according to the ratio of the memory consumption rate to the recycling rate, specifically including:

[0072] S31, detect the ratio of the memory consumption rate to the recycling rate;

[0073] S32, in the pre-configured step adjustment parameters, find the memory waterline difference adjustment parameter corresponding to the ratio of the currently detected memory consumption rate to the recycling rate;

[0074] S33, judge whether the current memory waterline difference is consistent with the found memory waterline difference adjustment parameter;

[0075] S34, if they are consistent, do nothing; if they are inconsistent, adjust the memory waterline difference according to the found memory waterline difference adjustment parameter.

[0076] If the system sends a direct recycling within a certain period of time, it is necessary to set the memory waterline difference in the current environment based on the ratio of the memory consumption rate to the recycling rate and the step adjustment parameter, and adjust it up or down. At this time, the memory occasionally shows a serious shortage, and the memory recycling rate is lower than the memory consumption rate. It is necessary to increase the recycling time and enthusiasm of the asynchronous recycling process, and probably adjust the memory waterline difference upward.

[0077] Specifically, if the ratio < 1, set the memory waterline difference in the current environment to 10. At this time, the difference between the high waterline and the low waterline is small, and the execution time of the asynchronous recycling process is shortened.

[0078] If 1 <= ratio < 1.2, set the memory waterline difference in the current environment to 30. At this time, the difference between the high waterline and the low waterline is medium, and the execution time of the asynchronous recycling process is medium.

[0079] If 1.2 <= ratio, set the memory waterline difference in the current environment to 80. At this time, the difference between the high waterline and the low waterline is large, and the execution time of the asynchronous recycling process is long.

[0080] If the current ratio exactly corresponds to the current memory waterline difference parameter, there is no need to adjust the memory waterline difference parameter.

[0081] S4. Monitor whether a direct recycling operation has not occurred again within a preset time interval.

[0082] S5. If a direct recycling operation occurs, continuously execute step S3.

[0083] S6. If a direct recycling operation has not occurred again, determine whether the ratio of the memory consumption rate to the recycling rate is less than 1, and the currently available memory of the system has been recycled to the high waterline state.

[0084] S7. If so, put the asynchronous recycling process into sleep; otherwise, continuously execute step S3.

[0085] If the direct recycling count does not increase within a period of time, and the ratio of the memory consumption rate to the recycling rate is less than 1, and the currently available memory of the system has been recycled to the high waterline state, then put the asynchronous recycling process into sleep to reduce resource consumption; the monitoring service enters the daemon state. Further, if the direct recycling count increases, repeat steps S2 - S7.

[0086] Embodiment III

[0087] In the above, the embodiments of an adaptive memory recycling control method have been described in detail. Based on the adaptive memory recycling control method described in the above embodiments, the embodiments of the present invention also provide an adaptive memory recycling control device corresponding to this method.

[0088] Figure 4 is a schematic block diagram of the structure of an adaptive memory recycling control device provided by Embodiment III of the present invention. As Figure 4 shown, the device includes a pre - configuration module, a monitoring module, an asynchronous recycling start - stop module, and an asynchronous recycling control module.

[0090] Monitoring module: Monitor whether a direct recycling operation occurs within a preset time interval.

[0091] Asynchronous recycling start-stop module: If a direct recycling operation occurs, start the asynchronous recycling process.

[0092] Asynchronous recycling control module: In the asynchronous recycling process, adjust the memory waterline difference according to the ratio of the memory consumption rate to the recycling rate, and the greater the ratio of the memory consumption rate to the recycling rate, the greater the memory waterline difference; where the memory waterline difference refers to the difference between the high waterline and the low waterline.

[0093] Among them, after the asynchronous recycling process is started, the monitoring module is also used to monitor whether a direct recycling operation has occurred within a preset time interval. If a direct recycling operation occurs, continuously run the asynchronous recycling control module; if no direct recycling operation has occurred again, monitor and determine whether the ratio of the memory consumption rate to the recycling rate is less than 1, and the current available memory of the system has been recycled to the high waterline state; if so, notify the recycling start-stop module to put the asynchronous recycling process into sleep; otherwise, continuously run the asynchronous recycling control module.

Therefore, the specific implementation in this device can be seen in the embodiment part of the adaptive memory recycling control method in the previous text.
