Abstract

A System for collecting execution information of hyper-threading in different states comprises a collection module, a setting interface, a storage module, and a state judgment module. The Hyper-Threading Testing System operates on a computing device that includes a central processing unit (CPU). The CPU can be in either a hyper-threading enabled state or a hyper-threading disabled state. The collection module collects operating information in the enabled state and operating information in the disabled state and stores it in an information storage unit of the storage module. The setting interface sets a hyper-threading switch parameter to an enabled state parameter or a disabled state parameter and stores it in a configuration file storage unit of the storage module. The state judgment module reads the hyper-threading switch parameter and sends a hyper-threading enabled signal or a hyper-threading disabled signal to put the CPU into a hyper-threading enabled state or a hyper-threading disabled state.

Description

System and method for collecting operation information of hyperthreads in different states

The present invention relates to a system and method for collecting operation information, and more particularly to a system and method for collecting operation information of a hyperthread in different states.

A thread is the smallest unit for scheduling operations in an operating system and runs in a processor core. In the prior art, since each processor core only contains one thread, a second thread cannot be executed simultaneously before the first instruction is completed.

However, not all instructions will occupy the processor's computing resources, so Intel proposed the hyper-threading (HT) technology. After the central processing unit (CPU) enters the hyper-threading state, each processor core can provide two parallel processing threads to execute more instructions when computing resources are sufficient.

System manufacturers often need to purchase a large number of CPUs and apply them to their own products. After the purchase, they also need to spend a lot of time collecting operating information. First, they need to confirm whether the CPU can correctly switch between the hyperthreading on state and the hyperthreading off state, that is, to confirm whether the CPU is faulty and needs to be replaced. Second, they need to confirm whether the operation of their own products meets expectations when the CPU is in the hyperthreading on state and the hyperthreading off state.

However, in the prior art, there is a lack of a system for collecting operating information while the central processing unit is switching between the hyperthreaded on state and the hyperthreaded off state. In other words, the operator needs to operate the central processing unit to enter the hyperthreaded on state or the hyperthreaded off state while collecting the operating information of the corresponding state, which not only requires a large number of steps, but also takes a lot of time.

In view of the fact that it generally takes a lot of time to collect operation information in the prior art, the main purpose of the present invention is to provide a system and method for collecting operation information of a hyperthread in different states, which is to set the hyperthread switch parameter so that the state judgment module sends a hyperthread on signal or a hyperthread off signal to the central processing unit, so that the central processing unit enters the hyperthread on state or the hyperthread off state, and then use the collection module and the storage module to collect the on state operation information or the off state operation information and store it, thereby shortening the operation information collection process and solving the above problem.

Accordingly, the first necessary technical means adopted by the present invention to solve the problems of the prior art is to provide a system for collecting operation information of hyperthreads in different states (hereinafter referred to as "operation information collection system"), which is operated on a computing device. The computing device includes a central processing unit (CPU). The central processing unit is operated to switch between a hyperthread on state and a hyperthread off state.

The operation information collection system includes a collection module, a setting interface, a storage module and a state judgment module. The collection module is used to collect the operation information of the central processing unit in the open state when the hyperthread is in the open state, and is used to collect the operation information of the central processing unit in the closed state when the hyperthread is in the closed state.

The setting interface is operated to set a hyperthread switch parameter to an on state parameter or a off state parameter. The storage module includes an information storage unit and a configuration file storage unit.

The information storage unit receives and stores the on-state operation information when the hyperthread is in the on-state, and receives and stores the off-state operation information when the hyperthread is in the off-state. The configuration file storage unit stores a configuration file, and the configuration file stores the hyperthread switch parameters set through the configuration interface.

The state judgment module reads the hyperthread switch parameter from the configuration file, and when the hyperthread switch parameter is an on state parameter, sends a hyperthread on signal to the central processing unit, so that the central processing unit enters the hyperthread on state, and when the hyperthread switch parameter is an off state parameter, sends a hyperthread off signal to the central processing unit, so that the central processing unit enters the hyperthread off state.

Based on the above necessary technical means, the following additional technical means can be derived. Preferably, the computing device can be a desktop computer, a laptop computer, an industrial computer, a tablet computer, a server or a mobile phone. Preferably, the status judgment module can be a Basic Input/Output System (BIOS) or a Unified Extensible Firmware Interface (UEFI).

Preferably, both the on-state operation information and the off-state operation information may include the number of operating cores, the operating frequency and the manufacturer name. Preferably, the configuration file may be encrypted, and the operation information collection system may further include a decryption determination module, which, when determining that the configuration file is encrypted, transmits a decryption signal to the configuration file storage unit to decrypt the configuration file, so that the state determination module can determine the hyperthread switch parameter in the decrypted configuration file.

Preferably, the operation information collection system may further include a restart determination module for determining whether to restart the computing device, and when it is determined that the computing device is to be restarted, a restart signal is sent to the central processing unit to restart the computing device.

Another necessary technical means adopted by the present invention to solve the problems of the prior art is to provide a method for collecting operation information of a hyperthread in different states (hereinafter referred to as "operation information collection method"), which is implemented using the above-mentioned operation information collection system and includes steps (a) to (c).

First, step (a) is to start the computing device and use the state determination module to determine whether the hyperthread switch parameter is an on state parameter or a off state parameter.

Next, in step (b), when it is determined in step (a) that the hyperthread switch parameter is an on-state parameter, the state determination module is used to send a hyperthread on-signal to the central processing unit, so that the central processing unit enters the hyperthread on-state, and the collection module is used to collect the on-state operation information of the central processing unit, and the on-state operation information is stored in the information storage unit.

Finally, in step (c), when it is determined in step (a) that the hyperthread switch parameter is a closed state parameter, the state determination module is used to send a hyperthread closed signal to the central processing unit, so that the central processing unit enters the hyperthread closed state, and the collection module is used to collect the closed state operation information of the central processing unit, and the closed state operation information is stored in the information storage unit.

Based on the above necessary technical means, the following subsidiary technical means can be derived. Preferably, step (a) can include a step (a1), which is when the decryption judgment module of the operation information collection system determines that the configuration file is encrypted, the decryption judgment module transmits a decryption signal to the configuration file storage unit to decrypt the configuration file for the state judgment module to determine the hyperthread switch parameters in the decrypted configuration file.

As mentioned above, step (a) may further include a step (a2), which is to use a setting interface to set the hyperthread switch parameter to an on state parameter and a off state parameter.

Preferably, the operation information collection method further includes a step (d) after step (b) or step (c), wherein when the restart determination module of the operation information collection system determines to restart the computing device, the restart determination module transmits a restart signal to the central processing unit, so that the computing device restarts and returns to step (a) and when the restart determination module determines not to restart the computing device, the step (d) is terminated.

In summary, the system and method for collecting operation information of a hyperthread in different states provided by the present invention is to set the hyperthread switch parameter so that the state judgment module sends a hyperthread on signal or a hyperthread off signal to the central processing unit, so that the central processing unit enters the hyperthread on state or the hyperthread off state, and then uses the collection module and the storage module to collect the on state operation information or the off state operation information and store it, thereby shortening the operation information collection process and solving the above-mentioned problem.

The specific implementation examples adopted in this creation will be further explained through the following implementation examples and drawings.

Since the system and method for collecting operation information of hyperthreads in different states provided by the present invention can be widely used in various computing devices, they will not be described one by one here. Only a preferred embodiment is listed for specific explanation, and this embodiment is only used to conveniently and clearly assist in explaining the purpose and effect of the embodiment of the present invention.

Please refer to the first figure, which is a system block diagram of the hyperthread operation information collection system provided by the present invention in different states. As shown in the first figure, a hyperthread operation information collection system in different states (hereinafter referred to as "operation information collection system") 100 is running on a computing device 200.

In the present invention, the computing device 200 may be a desktop computer, a laptop computer, an industrial computer, a tablet computer, a server or a mobile phone. The computing device 200 includes a central processing unit (CPU) 201. The CPU 201 is operated to switch between a hyperthreading-on state and a hyperthreading-off state.

Hyper-threading (HT) technology was proposed by Intel Corporation, which enables one physical computing core to provide two threads for parallel processing of instructions, making full use of the computing resources of the computing core, and can also be regarded as two virtual computing cores. In mainland China, it is also called hyperthreading technology. The detailed structure and working principle of hyperthreading technology are prior arts and will not be elaborated in this embodiment.

The operation information collection system 100 includes a collection module 1, a setting interface 2, a storage module 3, a state judgment module 4, a decryption judgment module 5 and a restart judgment module 6. The collection module 1 is used to collect an on-state operation information of the central processing unit 201 with a collection signal S1 when the hyperthread is on, and is used to collect a off-state operation information of the central processing unit 201 with a collection signal S1 when the hyperthread is off.

Both the on-state running information and the off-state running information include the number of running cores, the running frequency, and the vendor name. When the hyperthreading is on, since one physical computing core includes two virtual computing cores, the number of running cores of the CPU 201 when the hyperthreading is on is twice the number of running cores of the CPU 201 when the hyperthreading is off.

In addition, if a heavy-load computing instruction is issued to the central processing unit 201, the operating frequency of the central processing unit 201 when the hyperthreading is turned on will be significantly lower than the operating frequency of the central processing unit 201 when the hyperthreading is turned off.

On the other hand, if a lightly loaded computing instruction is issued to the central processing unit 201, the operating frequency can be kept fixed. In other embodiments, the on-state operating information and the off-state operating information can include other parameters related to the central processing unit 201. The setting interface 2 is operated to set a hyperthread switch parameter to an on-state parameter or a off-state parameter. In practice, the on-state parameter or the off-state parameter can be defined as 1 and 0, respectively, representing an on-state and a off-state, respectively. In addition, in the present invention, the setting interface 2 can be a manual setting interface or an automatic setting interface. When the setting interface 2 is a manual setting interface, an operator can manually set the hyperthread switch parameters. Usually, the manual setting interface is a user interface displayed on the screen. When the setting interface 2 is an automatic setting interface, the hyperthread switch parameters can be automatically set through a program script.

The storage module 3 includes an information storage unit 31 and a configuration file storage unit 32. The information storage unit 31 receives the operation information of the open state with a storage signal S2 when the hyperthread is in the open state and stores it, and receives the operation information of the closed state with a storage signal S2 when the hyperthread is in the closed state and stores it. In the present invention, the information storage unit 31 is a data folder in the hard disk, and can be stored in data folders with different names corresponding to different operation information.

The configuration file storage unit 32 stores a configuration file, and the configuration file stores the hyperthreading switch parameters set by the configuration interface 2. In the present invention, the configuration file storage unit 32 is a memory chip of the motherboard.

The state judgment module 4 reads the hyperthread switch parameter from the configuration file, and when the hyperthread switch parameter is an on state parameter, sends a hyperthread on signal S3 to the central processing unit 201, so that the central processing unit 201 enters the hyperthread on state, and when the hyperthread switch parameter is a off state parameter, sends a hyperthread off signal S4 to the central processing unit, so that the central processing unit 201 enters the hyperthread off state.

In the present invention, the state determination module 4 can be a Basic Input/Output System (BIOS) or a Unified Extensible Firmware Interface (UEFI). The Basic Input/Output System and the Unified Extensible Firmware Interface are two types of motherboard firmware, which define how the computing device 200 boots and from which hard disk it boots, and are both prior arts, and will not be described in detail in this embodiment.

When the decryption judgment module 5 judges that the configuration file is encrypted, it transmits a decryption signal S5 to the configuration file storage unit 32 to decrypt the configuration file. The configuration file stores various parameters that can affect the performance of the central processing unit 201, not only the switch of the hyperthreading, but also the operation of the central processing unit 201. Therefore, in most cases, the configuration file will be encrypted and protected, and the decryption signal S5 is the corresponding password for decryption.

The restart determination module 6 is used to determine whether to restart the computing device 200, and when it is determined that the computing device 200 is to be restarted, a restart signal S6 is sent to the central processing unit 201 to restart the computing device 200.

Please refer to FIG. 2, which is a flowchart showing the steps of the method for collecting operation information of a hyperthread in different states provided by the present invention, and please refer to FIG. 1 together. As shown in FIG. 2, the method for collecting operation information of a hyperthread in different states (hereinafter referred to as "the method for collecting operation information") is implemented using the operation information collection system 100, and includes steps S110 to S220.

First, step S110 is to start the computing device 200. Then, step S120 is to use the decryption determination module 5 to determine whether the configuration file is encrypted. Please refer to the description of the decryption determination module 5 above for whether the configuration file is encrypted. If the configuration file is encrypted, step S130 is to use the decryption determination module 5 to transmit the decryption signal S5 to the configuration file storage unit 32 and decrypt the configuration file.

If the file is not encrypted or has been decrypted, step S140 is to set the hyperthread switch parameter to an on state parameter or a off state parameter using the setting interface 2. Then, step S150 is to use the state determination module 4 to determine whether the hyperthread switch parameter is an on state parameter.

When the hyperthread switch parameter is determined to be an on state parameter in step S150, step S160 utilizes the state determination module 4 to send the hyperthread on signal S3 to the central processing unit 201, so that the central processing unit 201 enters the hyperthread on state.

Then, step S170 is to utilize the collection module 1 to collect the opening state operation information of the central processing unit 201, and store the opening state operation information in the information storage unit 31.

Finally, step S180 utilizes the restart determination module 6 to determine whether to restart the computing device 200. If yes, the restart determination module 6 sends a restart signal S6 to the central processing unit 201 to restart the computing device and return to step S110. If no, step S180 ends.

Returning to step S150, when step S150 determines that the hyperthread switch parameter is not an on state parameter, that is, the hyperthread switch parameter is a off state parameter at this time, the process proceeds to step S190. Step S190 utilizes the state determination module 4 to send the hyperthread off signal S4 to the central processing unit 201, so that the central processing unit 201 enters the hyperthread off state.

Next, step S200 utilizes the collection module 1 to collect the shutdown state operation information of the central processing unit 201, and stores the shutdown state operation information in the information storage unit 31.

Finally, step S210 utilizes the restart determination module 6 to determine whether to restart the computing device 200. If yes, the restart determination module 6 sends a restart signal S6 to the central processing unit 201 to restart the computing device and return to step S110. If no, step S210 ends.

In step S170 and step S200, in order to prevent confusion, each time the operation information (including the open state operation information and the closed state operation information) is stored, the information storage unit 31 may be cleared first (in this embodiment, the data folder is cleared). In addition, since the information storage unit 31 is a data folder in this embodiment, the operation information collection system 100 may further include a data folder detection module (not shown) for creating a data folder for storing the open state operation information or the closed state operation information when it is detected that the data folder has not been created.

In step S180 and step S210, the restart determination module 6 can manually or automatically determine whether to restart the computing device 200. When manually determining, the operator can determine whether the currently collected operation information meets the operation information collection requirements. For example, if only the on-state operation information is collected in the current operation information collection process (step S110 to step S180), the operator can decide to restart the computing device 200 and use the setting interface 2 to set the hyperthread switch parameter to the off-state parameter in the next round of operation information collection process and then collect the off-state operation information.

When automatically determining, the number of executions can be set in the program script. For example, when executing to step S180 or step S210, and the restart determination module 6 determines that the number of executions has not yet met the number of executions set in the program script, a restart signal S6 is sent to the central processing unit 201 to restart the computing device 200 and return to step S110. In this way, the required number of operation information can be automatically collected and a lot of time can be saved.

In addition, the types of operation information that need to be collected can also be set in the program script. For example, when executing to step S180, and the restart determination module 6 determines that only the open state operation information is currently collected, the restart signal S6 is sent to the central processing unit 201 to restart the computing device 200 and return to step S110. At step S140, the hyperthread switch parameter is set to the closed state parameter through the setting interface 2 to collect the closed state operation information. In this way, the required types of operation information can be collected automatically and a lot of time can be saved.

In summary, the system and method for collecting operation information of a hyperthread in different states provided by the present invention sets the hyperthread switch parameter so that the state judgment module 4 sends the hyperthread on signal S3 or the hyperthread off signal S4 to the central processing unit 201, thereby causing the central processing unit 201 to enter the hyperthread on state or the hyperthread off state, and then utilizes the collection module 1 and the storage module 3 to collect and store the on state operation information or the off state operation information, thereby shortening the operation information collection process and solving the above-mentioned problem.

The above detailed description of the preferred specific embodiments is intended to more clearly describe the features and spirit of the present invention, but is not intended to limit the scope of the present invention by the preferred specific embodiments disclosed above. On the contrary, the purpose is to cover various changes and arrangements with equivalents within the scope of the patent application for the present invention.
