detailed description

 The technical solutions in the embodiments of the present invention are clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The embodiment of the present invention can be applied to a system capable of running a virtual machine or a runtime. For example, the system shown in FIG. 1 includes: a system management module (Sy st em Manager), and a logical device. The number of logical devices is at least two or more. The functions of the system management module include: managing system hardware and dividing hardware resources of logical devices. The idle monitoring module (I dle Mon it or ) is included in the logical device, and the functions of the idle monitoring module include: The idle monitoring module in the device separately monitors the idle state of the logical device, and when the time when the logical device is in the Idle state exceeds a certain threshold or the logical device actively sleeps/sleeps, the logical device sends a pause to the management module ( Suspend) request, indicating that the logical device may suspend execution for a long time thereafter, the resources of the logical device may be released, and used for other logical devices or for other purposes.

 As shown in FIG. 1a, the idle monitoring module in a virtual machine detects the Idle process of the virtual machine. When the virtual machine is in the Idle state for more than a certain threshold, the virtual machine 1 or the virtual machine actively enters. In the sleep/hibernation state, as shown in the virtual machine 2 in the figure, the virtual machine 1 and the virtual machine 2 will release system resources such as cpu core and memory, and are managed by the system management module, and the virtual machine 1 and the virtual machine 2 are interrupted. It is also monitored by the system management module; when the virtual machine is reactivated, the system management module re-allocates the virtual machine with system resources such as cpu core and memory, and resumes execution of the virtual machine, as shown in virtual machine 3, the system management module will be interrupted. Passed to the virtual machine 3.

 For another example: As shown in Figure lb, the runtime system includes: system management module, runtime (runtime) 1, runtime 2. The runtime library code and application code are compiled into a program that causes the applications in Runtime 1 and Runtime 2 to run directly on the hardware environment. When the runtime is running for the JVM (Java Virtual Machine), the JVM can directly access the hardware resources, running the application supported by the JVM; when running LibOS (Library Operating System), the application runs directly LibOS runtime environment.

 For another example: as shown in Figure lc, a lightweight virtualization system/de-virtualization system/partition system, etc., which can allocate exclusive hardware partitions to virtual machines, including: System Management Module (Virtual System Manager), Virtual Machine (VM). The hardware is partitioned, and virtual machine 1 and virtual machine 2 have various hardware resources, and virtual machine 1 and virtual machine 2 can directly access the hardware.

 An embodiment of the present invention provides a method for managing system resources, as shown in FIG. 1d, including:

101. Determine, according to hardware resource utilization of each logical device in the system, a first type of logical device.

The logical device in the system includes a virtual machine and a runtime; the first type of logical device includes at least a sleep state, a sleep state, and an idle time greater than or equal to A valued logical device.

 In this embodiment, the system management module in the system can determine the first type of logical device according to the hardware resource utilization of each logical device in the system. For example, in each virtual machine in the system, a monitoring module is set, and the monitoring module is used to monitor parameters such as running status, idle time, and information flow of the virtual machine, which reflect hardware resource utilization. Among them, the parameters such as running status, idle time, and information flow can be weighted, and the result of the weighting calculation is taken as the hardware resource utilization rate.

 For example, the system management module can determine the process executed by each logical device in real time, or the logical device can report the process executed in the virtual machine to the system management module in real time; the system management module can identify the type of the process currently executed by the logical device, and according to Each type of process acquires the hardware resource utilization of the logical device for the occupation of hardware resources. For example, the Idle process is a process that is executed when the logical device is idle. If the idle monitoring module in the logical device detects that the logical device is running the Idle process, the logical device belongs to the first type of logical device.

 1 02. Release the hardware resources occupied by the first type of logical device.

 For example: The logical device sends a pause request to the system management module. After the system management module receives the information of the pause request, the system management module takes over the virtual machine interrupt monitoring right, and releases the hardware resources such as the cpu core and the memory of the logical device.

 1 03 , allocate the released hardware resources to the second type of logical device.

 The logical device other than the first type of logical device in the system further includes the second type of logical device. For example: In the system, there is a running logical device, but the logical device has insufficient hardware resources to achieve efficient operation, and this logical device can be used as the second type of logical device;

For another example: in the system, because the hardware resources of the hardware device such as the server, the computer, and the like that are carrying the system are limited to the system, and the logical device is waiting for the allocated hardware resources, the logical device that is waiting for the allocated hardware resources is Can be used as a second type of logical device. The specific implementation process of allocating the released hardware resources to the second type of logical device is: The system management module uses the detected re-awakened logical device and the logical device currently in the queued resource as the second type of logical device, and the system management module reassigns the recovered hardware resource according to the requirement of the logical device. Two types of logical devices.

 The method for managing a system according to the embodiment of the present invention determines, according to the hardware resource utilization of each logical device in the system, a resource such as a logical device that is in a sleep state, is in a sleep state, and has an idle time greater than or equal to a threshold value. The hardware resources occupied by the low-utilization logical devices allocate the released hardware resources to the logical devices that need hardware resources. Compared with the prior art, the present invention can release and allocate hardware resources of logical devices with low hardware resource utilization to other logical devices in the system, thereby reducing logical devices that cannot be efficiently operated or waiting for allocation due to insufficient hardware resources. The situation of resources occurs, so that the actual hardware resources in the server can support more logical devices to run at the same time, thus saving the time for the server to process data, improving the efficiency of the server processing data, and reducing the energy consumption of the server.

 In this embodiment, after the first type of logical device is determined according to the hardware resource utilization rate of each logical device, the system management module may release the hardware resource and redistribute the released resource. The system management module can determine the first type of logical device by a pause request message sent by a logical device in the system. Therefore, on the basis of the method shown in Figure Id, 01 can be implemented as 201-202 as shown in Figure 2:

 2 01. Receive a pause request sent by a logical device in the system.

 The suspend request message is sent by a logical device that has a lower hardware resource utilization condition, such as a logical device before entering the sleep state, a logical device before entering the sleep state, or a logical device with an idle time greater than or equal to the threshold. For example, as shown in FIG. 2a, when the idle monitoring module in the virtual machine 1 detects that the virtual machine 1 is ready to actively sleep or the virtual machine 1 enters an idle state and the idle time is greater than the threshold, the virtual machine 1 issues a pause to the system management module. Request message.

 2 02, the logical device that sent the pause request message is used as the first type of logical device.

For example, as shown in FIG. 2a, the virtual machine 1 issues a pause request message to the system management module, where the virtual machine 1 is a first type of logical device. 203. Release hardware resources occupied by the first type of logical device.

 204. Allocate the released hardware resources to the second type of logical device.

 The logical device other than the first type of logical device in the system further includes the second type of logical device.

 The method for managing a system according to the embodiment of the present invention determines, according to the hardware resource utilization of each logical device in the system, a resource such as a logical device that is in a sleep state, is in a sleep state, and has an idle time greater than or equal to a threshold value. The hardware resources occupied by the low-utilization logical devices allocate the released hardware resources to the logical devices that need hardware resources. Compared with the prior art, the present invention can release and allocate hardware resources of logical devices with low hardware resource utilization to other logical devices in the system, thereby reducing logical devices that cannot be efficiently operated or waiting for allocation due to insufficient hardware resources. The situation of resources occurs, so that the actual hardware resources in the server can support more logical devices to run at the same time, thus saving the time for the server to process data, improving the efficiency of the server processing data, and reducing the energy consumption of the server.

 In this embodiment, the system management module in the system may first save the running state of the first type of logical device that has released the hardware resource, so that when the first type of logical device is awake again, not only can The first type of logical device allocates hardware resources, and can also load an operating state of the first type of logical device. Therefore, on the basis of the embodiment shown in FIG. 1 d and FIG. 2, an embodiment as shown in FIG. 3 is further included:

 301. Receive a pause request sent by a logic device in the system;

 The pause request is sent by the logical device before entering the sleep state in the system, the virtual machine before entering the sleep state, and the logical device whose idle time is greater than or equal to the threshold.

 302. The logical device that sends the pause request message is used as the first type of logical device.

303. Save an operating state of the first type of logical device that has released the hardware resource. For example: the logical device sends a pause request to the system management module. After the system management module receives the information of the pause request, the system management module takes over the logical device interrupt monitoring right, and saves the current running state of the logical device, and releases the cpu core of the logical device. System resources such as memory. Its The current running state may at least include: a result calculated during the running of the program, and a progress of the running of the program.

 It should be noted that the management module can execute 301 - 302 and 303 at the same time, or can be executed in a certain order.

 After the hardware resources occupied by the first type of logical device are released, the hardware resources are allocated to the first type of logical device and the running state is loaded.

 For example, as shown in FIG. 3a, after receiving the device interrupt information of the logical device, the system management module wakes up the corresponding interrupt monitoring instance. The interrupt monitoring instance is created for the logical device after the system management module receives the interrupt request sent by the virtual machine, and may include a thread and a process. The interrupt monitoring instance may specifically include information such as a logical device identifier, a logical device state, and the like, wherein the logical device state mainly includes: the logical device has been completely suspended, the logical device is in the pause process, and the logical device has resumed operation. After that, the interrupt monitoring instance allocates hardware resources such as cpu and memory to the logical device according to the configuration information of the virtual machine, and loads the running state saved when the logical device is suspended from the disk or the memory, and restores the logical device on the newly allocated hardware resource. In the running state, the device is interrupted and delivered to the logic device that resumes execution, and the interrupt monitoring of the logical device is released.

 305. Allocate the released hardware resources to the second type of logical device.

 The logical device other than the first type of logical device in the system further includes the second type of logical device.

 It should be noted that the system management module can execute 304 and 305 at the same time, or can be executed in a certain order.

The method for managing a system according to the embodiment of the present invention determines, according to the hardware resource utilization of each logical device in the system, a resource such as a logical device that is in a sleep state, is in a sleep state, and has an idle time greater than or equal to a threshold value. The hardware resources occupied by the low-utilization logical devices allocate the released hardware resources to the logical devices that need hardware resources. Compared with the prior art, the present invention can release and allocate hardware resources of logical devices with low hardware resource utilization to other logical devices in the system, thereby reducing logical devices caused by insufficient hardware resources. The inability to run efficiently or wait for the allocation of resources occurs, so that the hardware resources actually existing in the server can support more logical devices to run at the same time, thus avoiding repeatedly releasing the hardware resources when the first type of logical devices are awake again. The previous operation saves the time for the server to process data, improves the efficiency of the server processing data, and reduces the energy consumption of the server.

 An embodiment of the present invention provides a method for managing system resources. As shown in FIG. 4, the method may be implemented by a logic device in the system shown in FIG. 1, and includes:

 401. Detect whether the first type of logical device is based on a hardware resource utilization of the logical device in the system.

 The logic device in the system includes a logic device and a runtime; the first type of logic device includes at least a logic device that is in a sleep state, is in a sleep state, and has an idle time greater than a threshold value in the system.

 402. If it is the first type of logical device, send a pause request message to the system management unit, so that the system management unit determines, according to the pause request message, that the logical device is the first type of logical device, and The hardware resources occupied by the logical device are released, and the released hardware resources are allocated to the second type of logical device.

 The logic device in the system other than the first type of logic device includes the second type of logic device. If it is not the first type of logical device, no processing is performed.

 For example, there is a logic device that sends a pause request message to the system management unit, and then the system management unit determines that the logical device is the first type of logical device according to the received pause request information, and releases the logical device occupation. Hardware resources, then re-allocate the reclaimed released hardware resources to logical devices that require hardware resources.

The method for managing a system according to the embodiment of the present invention determines, according to the hardware resource utilization of each logical device in the system, a resource such as a logical device that is in a sleep state, is in a sleep state, and has an idle time greater than or equal to a threshold value. The hardware resources occupied by the low-utilization logical devices allocate the released hardware resources to the logical devices that need hardware resources. Compared with the prior art, the present invention can release and allocate hardware resources of logical devices with low hardware resource utilization to other logical devices in the system, thereby reducing logical devices caused by insufficient hardware resources. The inability to run efficiently or wait for resource allocation occurs, so that the actual hardware resources in the server can support more logical devices to run at the same time, thus saving the time for the server to process data, improving the efficiency of the server processing data, and reducing The energy loss of the server.

 Further, in the example of the present application, after the terminal is executed 402, the first type of logical device releases the hardware resource, and the system management module recovers and allocates the released hardware resource to the second type of logical device. When the first type of logical device is awake again, the first type of logical device is restored according to an operating state when the first type of logical device releases resources. Therefore, based on the embodiment shown in FIG. 4, an embodiment as shown in FIG. 5 may also be included, which is executed by a logic device in the system as shown in FIG.

 501. Detect, according to the hardware resource utilization of the logical device, whether the first type of logical device is detected. The first type of logic device includes at least a logical device that is in a sleep state, is in a sleep state, and has an idle time greater than or equal to a threshold value in the system.

 502. If it is the first type of logical device, send a pause request message to the system management unit, so that the system management unit determines, according to the pause request message, that the logical device is the first type of logical device, and The hardware resources occupied by the logical device are released, and the released hardware resources are allocated to the second type of logical device.

 The logic device in the system other than the first type of logic device includes the second type of logic device. If it is not the first type of logical device, no processing is performed.

 503. Receive hardware resources allocated by the system management unit and sent operating state information, where the running state information records an operating state of the logical device before being released by the system management unit.

 For example, if a first type of logical device releases hardware resources, the system management module not only recovers the hardware resources released by the first type of logical devices, but also records the running state of the first type of logical devices when the hardware resources are released. The running status may include: cpu register information used by the logical device, memory information used by the logical device, and device status.

504. Load, according to the running state information, an operating state before the logical device is released by the system management unit. For example: A logical device that has been reclaimed hardware resources is awake again. At this time, the system management module not only allocates the hardware resources of the logical device, but also loads the operating state before the logical device releases the hardware resources. The operation before the first type of logic device is repeatedly awake and the hardware resources are repeatedly released is avoided, the time for processing the data by the server is saved, the efficiency of processing the data by the server is improved, and the energy loss of the server is also reduced.

 The embodiment of the present invention further provides an apparatus 60 for managing system resources. As shown in FIG. 6, the apparatus 60 includes:

 The collecting unit 61 is configured to: according to hardware resource utilization of each logical device in the system, the logical device in the system includes a virtual machine and a runtime; determining a first type of logical device, where the first type of logical device includes at least A logical device in the system that is in a sleep state, is in a sleep state, and has an idle time greater than or equal to a threshold.
