Embodiments of the invention

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention.

Cgroup (Control group) is a mechanism provided by the Linux kernel that can limit the resources used by a single or multiple processes, and can achieve fine-grained control over resources such as processors and memory. In order to improve the performance of the processor in the server and improve the user experience, this application uses the processor points method to add parameters to the cgroup, thereby controlling points and adjusting the performance of the processor.

According to an embodiment of the present invention, an embodiment of a processor performance adjustment method is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and, Although a logical sequence is shown in the flowcharts, in some cases the steps shown or described may be performed in a sequence different from that herein.

This embodiment provides a processor performance adjustment method, which can be used in terminals such as mobile phones, tablets, computers, etc. Figure 1 is a flow chart of a processor performance adjustment method according to an embodiment of the present invention, as shown in Figure 1 , the process includes the following steps:

S11. In response to the point recharge instruction, determine the current points of the processor.

Enable the points function for the created cloud host and configure its information. The configuration information includes the point configuration of the processor in the cloud host. The point configuration of the processor includes the upper point threshold of the processor, that is, the points that the processor can accumulate. Maximum points value.

Modify the points recharge instruction under the cgroup of the virtual machine and set parameters in the points recharge instruction to recharge points for the processor. When the cloud host is turned on, there may still be points in the processor itself. When recharging points, the current points of the processor can be determined by adding the recharged points with the existing points.

S12: Obtain the current operating performance of the processor, compare the current operating performance with the preset computing power threshold, and obtain the comparison result.

The preset computing power threshold is set in advance based on the processor's own specifications and performance, which is the baseline performance. When the cloud host is running, it may run in a mode that is lower than the preset computing power threshold, or it may run in a mode that exceeds the preset computing power threshold. The comparison result is obtained by comparing the current operating performance with the preset computing power threshold.

S13: According to the comparison result, adjust the current points of the processor to adjust the performance of the processor.

When the current operating performance is less than the preset computing power threshold, that is, when the cloud host is running in a mode lower than the baseline performance, the current points of the processor will increase with the passage of time, that is, the accumulated current points will not exceed the preset Set the upper limit of points threshold. When the current operating performance is greater than the preset computing power threshold, that is, when the cloud host is running in a mode higher than the baseline performance, and the processor usage reaches the quota, you can use the accumulated current points to additionally use the processor computing power. Until the points are consumed, the processor's computing power will fall back to the quota value until points are accumulated again or points are recharged.

The processor performance adjustment method provided by the embodiment of the present invention recharges points through a point recharge instruction to determine the current points of the processor. When the processor is running, it determines the operating performance of the processor and the size of the preset computing power threshold, and performs The accumulation or consumption of points means adjusting the current points of the processor, so that when the processor is running higher than the preset computing power threshold, it can improve the performance of the processor by consuming the accumulated points. This method can flexibly adjust the processing server performance and improve user experience.

This embodiment provides a method for determining the current points of the processor, which can be used for terminals such as mobile phones, tablets, computers, etc. Figure 2 is a flow chart of the method of determining the current points of the processor according to this embodiment, as shown in Figure 2 As shown, the process includes the following steps:

S21. In response to the creation instruction of the control group, create a control group of the processor, and the control group corresponds to the processor one-to-one.

S22. In response to the points recharge instruction, set points parameters in the control group of the processor to determine the current points of the processor.

You can limit the overall utilization of a virtual machine by modifying the processor parameters under the virtual machine control group (cgroup). The limit for virtual processor threads is to create a cgroup for each virtual processor and set it in the virtual processor's cgroup. Set processor parameters in . That is, the parameters are set in the control group of the processor through the point recharge instruction to determine the current points of the processor. Specifically, determining the current points also includes the following steps:

(1) In response to the points recharge instruction, set the points parameters in the control group of the processor to determine the recharge points of the processor.

The points value is written into the parameters of the point recharge instruction, that is, the points are recharged to the processor, thereby determining the recharge points to the processor.

(2) Obtain the current points of the processor and add the recharge points to the current points to determine the current points of the processor.

Obtain the current points of the processor and add the value of the recharge points to the current points value. If the accumulated current points value exceeds the preset points upper limit threshold, the current points value is set to the points upper limit threshold.

In one embodiment, before comparing the current running performance with the preset computing power threshold and obtaining the comparison result, the method further includes: obtaining the performance of the processor, and responding to the performance threshold configuration instruction for the processor, based on the performance of the processor Determine the preset computing power threshold.

Among them, the preset computing power threshold is the baseline performance.

This embodiment provides a method for adjusting processor performance, which can be used for terminals such as mobile phones, tablets, computers, etc. Figure 3 is a flow chart of the method for adjusting processor performance according to this embodiment, as shown in Figure 3. The process includes the following steps:

S31, when the current running performance exceeds the preset computing power threshold, current points are consumed.

S32: When the current running performance does not reach the preset computing power threshold, current points are accumulated to increase the computing power of the processor.

Specifically, it includes the following steps:

(1) When the current operating performance does not reach the preset computing power threshold, the current points are accumulated and the current points are obtained.

When the current operating performance is less than the preset computing power threshold, that is, when the cloud host is running in a mode lower than the baseline performance, the current points of the processor will increase over time, that is, the current points will be accumulated.

(2) In response to the integral upper limit instruction, determine the integral upper limit threshold of the processor.

After the points function is enabled on the created cloud host, you can configure its information. You can use the points upper limit command to configure the processor points and set the processor's points upper limit threshold.

(3) Compare the current points with the points upper limit threshold. When the current points exceed the points upper limit threshold, adjust the current points to the points upper limit threshold.

Compare the accumulated current points with the upper limit threshold of points. Since the accumulated current points do not exceed the preset upper limit threshold of points, when the current points exceed the upper limit threshold of points, the current points value is set to the upper limit threshold of points, that is to say, the current points The maximum value of the points is the points upper limit threshold.

When the current operating performance is greater than the preset computing power threshold, that is, when the cloud host is running in a mode higher than the baseline performance, and the processor usage reaches the quota, you can use the accumulated current points to additionally use the processor computing power. Until the points are consumed, the processor's computing power will fall back to the quota value until points are accumulated or recharged again.

This embodiment provides a specific embodiment of a processor performance adjustment method, as shown in Figure 4.

In this embodiment, the integration of the processor is controlled by adding three parameters to the cgroup. The parameters are as follows:

cpu.cfs_burst_ns: Indicates the maximum points that can be accumulated, that is, the upper limit threshold of points. The parameter can be read and written. 0 (default value) means that the processor credit mechanism is not enabled. Setting other parameters means that the credit mechanism is enabled.

cpu.cfs_remain_time: Indicates the currently available processor points, that is, the current points of the processor. The parameter is read-only.

cpu.cfs_recharge_time: Indicates the processor points recharge parameters, that is, recharge points. The parameters can be read and written. Writing a number to this interface indicates recharging processor points.

Os (OpenStack) will monitor the resume event of the cloud host, and libvirt (virtualization management software) will report this event after the virtual machine starts, migrates, restarts, and changes configuration normally. The OS calls the interface of libvirt to configure the processor points. When the points function is enabled for the created cloud host, its configuration information includes the points configuration of the processor, such as:

<global_period>100000</global_period>

<global_quota>50000</global_quota>

</cputune>

.....

</domain>

Among them, global_burst is the upper limit threshold of points for the processor. This configuration in the xml indicates that the cloud host has enabled the points mechanism. When the cloud host is turned on, the remaining points of the cloud host will be restored by calling the recharge interface of libvirt.

libvirt supports limiting the overall processor usage of the virtual machine process (global_period/global_quota), the processor usage of the vcpu (virtual processor) thread (period/quota), and the processor usage of other QEMU threads (such as io threads), etc. wait.

libvirt limits the overall utilization of the virtual machine by modifying the processor parameters under the virtual machine cgroup. The restriction on vcpu threads is to create a cgroup (called vcpu cgroup) for each vcpu and set the processor parameters in the vcpu group. .

Since processor points are limited for the entire virtual machine process, when implementing the libvirt control processor points function, you only need to modify the cpu.cfs_burst_ns and cpu.cfs_recharge_time parameters under the virtual machine cgroup.

The processor points mechanism can be turned on by modifying the cpu.cfs_burst_ns parameter. When the process is idle, the CPU points slowly accumulate until the points reach the upper limit of cpu.cfs_burst_ns and stop accumulating. The process is busy, and when the processor usage reaches the quota, you can use the accumulated points to use additional processor computing power. When the points are consumed, the processor usage will fall back to the quota value until there are more points available. .

When recharging processor points for a process, you can directly write the point value into the cpu.cfs_recharge_time parameter. At this time, cgroup will accumulate the value of cpu.cfs_recharge_time to cpu.cfs_remain_time. If the accumulated value of cpu.cfs_remain_time exceeds the cpu.cfs_burst_ns limit, Then set the cpu.cfs_remain_time value to cpu.cfs_burst_ns.

When the cloud host is shut down, the processor points need to be reported, that is, the remaining points of the cloud host will be retained after the shutdown, so that the saved points can be continued to be used the next time it is turned on. The implementation logic is as follows:

After the cloud host shuts down, the corresponding QEMU process will be terminated. When libvirt detects the QEMU process termination event, it obtains the remaining points in the cgroup of the virtual machine, and then reports the remaining points to the OS through the VIR_DOMAIN_EVENT_ID_TUNABLE event.

For example, the data reported by the event received by the OS is as follows:

{'cputune.global_remain_time':15563169L,'cputune.global_burst':36000000000L}

The OS listens to this event and persists the remaining points in the event processing interface.

In one implementation, when the virtual machine migrates data to the target virtual machine, the current score of the processor in the virtual machine is obtained, the current score is saved, and the current score is added to the target virtual machine.

If the points function is enabled on the cloud host before migration and there are remaining points, then after the migration, the points function must be enabled on the target cloud host and the remaining points restored to ensure that the migration operation does not affect the points of the virtual machine.

The cloud host migration operation is initiated by the OS. If it is a live migration, the migration process is mainly controlled by libvirt. In the case of cold migration, the migration process is mainly controlled by the OS. No matter which party controls it, the remaining points need to be saved first. After the target cloud host is started, the remaining points are recharged to the target cloud host. The target cloud host is the target virtual machine.

Specifically, after the OS initiates migration, the cloud host configuration information in libvirt's memory records the global_burst configuration that enables processor credits. Therefore, libvirt automatically sets the cgroup to enable the credits function when creating the target cloud host. During live migration, libvirt migrates the cloud host's data (memory data, device status, etc.) according to normal logic. After the migration is completed, libvirt immediately pauses the cloud host, obtains the remaining points of the processor in the virtual machine, that is, the current points, and adds The remaining points are recharged to the destination cloud host. After the points recharge is completed, restore the target cloud host. During cold migration, the cloud host persists the remaining points into the database when it shuts down. When it is turned on again after the migration, the OS listens to the resume event and recharges the remaining points to the target virtual machine.

The processor performance adjustment method provided by this application can accumulate the computing power of the cloud host through points when it is idle, and consume the accumulated processor points during the period when sudden performance is required to achieve excess use of the processor computing power. When the accumulated points are exhausted, the processor computing power can be limited to restore it to the baseline performance range. In addition to accumulating points during low-performance work, it can also be recharged through points, allowing users to recharge points according to actual needs. In addition, cloud host configuration, migration or power-on/off will not affect the processor points. It reduces the user's usage costs to a certain extent. There is no need to upgrade cloud hosts or purchase high-specification cloud hosts for occasional high processor usage services, improve resource utilization, and more flexibly configure and limit processor usage. performance, improving user experience.
