Description

Memory stress testing method, system and related components without operating system support

technical field

The present invention relates to the technical field of computers, in particular to a memory stress testing method, system and related components without the support of an operating system.

Background technique

With the rapid development of science and technology, artificial intelligence, Internet of Things and other technologies are becoming more and more common in people's lives. The application of big data requires high-end servers to support. The memory is an important part of the server. The operation data of the processor and the data exchanged by the external memory are temporarily stored in the memory. Therefore, the stress test of the memory is one of the important test indicators for the stability of the server.

At present, when performing memory stress testing, memory testing tools are usually run under the Linux system, such as the memtester tool and the stressapptest tool running under the Linux system. Taking the memtester tool as an example, the current memory stress testing solution is to first install the memtester tool in the system disk under the Linux system, and then compile, install, and run it. Specifically, after the memtester tool is installed, the BIOS (Basic Input Output System) will perform self-check and obtain the first boot device according to the BIOS settings, thereby reading the MBR (Master Boot Record, MBR) of the first boot device. Master Boot Record). Then load the OS (Operating System, operating system), including loading the kernel kernel, then call the init process to obtain the run level information, then execute the rc.sysinit file, start various services in the kernel, and finally execute /etc/rc.d /rc.local file. After the OS is loaded, run the memtester tool through the OS to perform a memory stress test. For example, a 48-hour memory stress test is usually performed.

During the whole process of the memory stress test, such as the 48-hour memory stress test described above, since the test is performed by running the memtester tool through the OS, the system disk cannot be taken away for other purposes. However, in the case of server development, there are often cases where staff need to take away the system disk for other project purposes. The long-term occupation of the system disk by the memory stress test reduces development efficiency.

To sum up, how to effectively reduce the occupation time of the system disk during the memory stress test is a technical problem that those skilled in the art urgently need to solve.

Detailed ways

The core of the present invention is to provide a memory pressure testing method without the support of an operating system, which is beneficial to reduce the occupation time of the system disk during the memory pressure testing, and provides convenience for the development process of the staff.

In order to make those skilled in the art better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to FIG. 1. FIG. 1 is an implementation flow chart of a memory stress testing method without operating system support in the present invention. The memory stress testing method without operating system support may include the following steps:

Step S101: Install a preset memory stress testing tool in a non-system disk of the host to be tested.

Specifically, a memory pressure test tool can usually be installed under the Linux system, and the specific type of the memory pressure test tool can be set and adjusted according to actual needs. For example, in a specific embodiment of the present invention, the memory pressure test tool can be selected For more extensive application, memtest86+ with more complete functions.

Of course, in addition to installing the memory stress test tool under the Linux system, you can also install it under other systems. For example, you can install memtest86+ in the Legacy mode of the RHEL system. And it should be emphasized that the memory stress testing method without operating system support described in this application refers to that when the memory stress testing is specifically performed in step S103, the memory stress testing tool can run directly on the hard disk without the support of the operating system, However, when installing the memory pressure test tool described in step S101, the system disk still needs to be used.

And it can be understood that, since the solution of the present application needs to support the memory pressure test in step S103, the system disk can be taken away for other project purposes. In the non-system disk of the host being tested.

Step S102: After the host restarts and the BIOS reads the MBR boot of the system disk, compiles the boot item of the memory stress test tool.

After the memory stress test tool is installed in the non-system disk of the host to be tested, the host needs to be restarted. After the host is restarted, the BIOS usually performs a self-check, and obtains the first boot device according to the settings of the BIOS itself, and the first boot device is usually a system disk by default. After obtaining the system disk, the BIOS will read the MBR of the system disk to boot.

In the traditional solution, after the BIOS reads the boot of the MBR of the system disk, it will execute the subsequent OS startup process. In the solution of the present application, the boot item of the memory stress test tool is compiled, so that the memory stress test Tools can be run directly on the hard drive.

Further, in order to determine whether the memory stress test tool is installed correctly, the kernel version can also be judged after the host restarts and the BIOS reads the MBR boot of the system disk, and before compiling the boot item of the memory stress test tool.

Specifically, when it is judged that the kernel version of the host is inconsistent with the kernel version generated by the memory stress test tool, it means that the memory stress test tool may be installed incorrectly, and this implementation of the present application will exit the memory stress test process and output the first A prompt message enables the staff to detect the abnormal situation in time.

In addition, in addition to judging the kernel version, in another embodiment of the present invention, the initrd file is also judged, that is, after the host restarts and the BIOS reads the MBR boot of the system disk, the boot of the memory stress test tool is compiled. Before items, also include:

When it is determined that the initrd file of the host is inconsistent with the initrd file generated by the memory stress test tool, the process of memory stress test is exited and a second prompt message is output.

The specific content and form of the first prompt information and the second prompt information can be set and adjusted as required, and, in practical applications, the judgment of the kernel version and the order of judgment of the initrd file can be set as required. The setting and adjustment can also be performed at the same time. For example, in the embodiment disclosed in the following code, it is based on the bootprefix program in the memory pressure test tool, and at the same time, the kernel version and the initrd file are judged right and wrong. When the kernel version or the initrd file is wrong, the memory pressure of the application will be terminated. testing process.

Further, in a specific embodiment of the present invention, it is considered that the GRUB (GRand Unified Bootloader) configuration file and the LILO (Linux Loader, a Linux bootloader) configuration file are also the runtime of the memory stress test tool. Therefore, in order to ensure that the memory stress test can be performed correctly in the future, in this implementation, it is determined that the kernel version of the host is consistent with the kernel version generated by the memory stress test tool, and the initrd file of the host is determined. After it is consistent with the initrd file generated by the memory stress test tool, before compiling the boot items of the memory stress test tool, the GRUB configuration file and the LILO configuration file are also judged right or wrong. specifically:

Determine whether the GRUB configuration file of the host is consistent with the GRUB configuration file generated by the memory stress test tool, and determine whether the LILO configuration file of the host is consistent with the LILO configuration file generated by the memory stress test tool;

If the two items are consistent, that is, when it is determined that the GRUB configuration file of the host is consistent with the GRUB configuration file generated by the memory stress test tool, and the LILO configuration file of the host is determined to be consistent with the LILO configuration file generated by the memory stress test tool, you can Perform subsequent operations of compiling the boot items of the memory stress test tool.

Correspondingly, if at least one of the two items is inconsistent, exit the memory stress test process and output a third prompt message.

In a specific implementation manner, the code for judging right and wrong for the GRUB configuration file and the LILO configuration file may be as follows:

During specific implementation, the boot entry of the memory stress test tool is usually compiled after the kernel version, initrd file, GRUB configuration file, and LILO configuration file are all correct. For example, when the memory stress test tool is memtest86+, the boot item for compiling the memory stress test tool can be specifically: compile the initrd file to generate the boot item memtest86+grub.

The code in a specific embodiment can be expressed as:

Step S103: Run the memory stress testing tool based on the boot item of the memory stress testing tool to perform the memory stress test.

Since the boot item of the memory stress test tool is compiled, without the support of the operating system, the memory stress test tool can be run directly based on the boot item of the memory stress test tool to perform the memory stress test, that is, the memory stress can be directly run on the hard disk test tools.

When a memory stress test tool performs a memory stress test, it is usually based on the way of reading memory and writing memory. Of course, the specific test items can refer to the traditional memory pressure test items, and the test items can also be adjusted as needed, that is, in a specific implementation of the present invention, it can also include:

Receive the memory stress test item adjustment instruction, and adjust the test items in the memory stress test tool according to the memory stress test item adjustment instruction.

By adjusting the test items in the memory stress testing tool, it is beneficial to improve the flexibility of memory stress testing.

By applying the technical solutions provided by the embodiments of the present invention, the memory pressure test tool can be directly run on the hard disk, that is, the memory pressure test without the support of the operating system is realized. Specifically, the present application installs the memory stress testing tool in the non-system disk of the host to be tested, so that when the memory stress testing tool is subsequently used for memory stress testing, removing the system disk does not affect the operation of the memory stress testing tool. At the same time, the present application needs to make the memory stress test tool not need to run based on the operating system. The specific method is to compile the boot item of the memory stress test tool after the host restarts and the BIOS reads the MBR boot of the system disk, so that the solution of the present application is When running the memory pressure test tool, it is run based on the compiled boot items of the memory pressure test tool, and does not need to be run based on the operating system, so the application can directly run the memory pressure test tool on the hard disk. Since the application directly runs the memory stress test tool on the hard disk without the support of the operating system, the system disk can be taken away for other project purposes during the memory stress test, that is, the solution of the application is conducive to reducing memory The time occupied by the system disk during the stress test provides convenience for the development process of the staff.
