Embodiment Construction

[0027] Implementation

[0028] 1) Prepare Linux test platform (including test host platform and install Linux operating system on the test host);

[0029] 2) Power on the test host, enter the operating system, and log in as the root user;

[0030] 3) Copy the auto_run script and mpich tool to the Linux system desktop;

[0031] 4) Run the terminal program under the Linux system, and perform the following operations under terminal:

[0032] #cd / root / Desktop Enter

[0033] # . / auto_run Enter

[0034] Terminal is silent;

[0035] 5) View the process

[0036] #top

[0037] Display the xphl program corresponding to the number of threads, and the CPU occupancy rate reaches more than 90%;

[0038] 6) At this time, an int_res.csv file of recording time will appear in the / root / Desktop / result folder;

[0039] 7) The test machine continues to run the floating-point calculation performance test;

[0040] 8) After the CPU floating-point calculation performance test is completed, check the int_res.csv file ...

Abstract

The invention provides a method for automatically testing floating point calculation performance of a CPU (Central Processing Unit), belonging to the field of testing of floating point calculation performance of the CPU. The whole test is based on a linux operating system, and is suitable for various processor platforms in the industry; HPL.dat parameter input documents are automatically set by using CPU information grabbed under a system, and floating point calculation test parameters are automatically set by using hostname information and IP (Internet Protocol) addresses. 1_mpi and 1_commpxe toolkits do not need to be manually installed. At the beginning of operating a script, the information is grabbed; simple, time-saving, easily-operating and automatic testing is realized through the information, and a performance result is automatically stored.

Description

technical field [0001] The invention relates to the field of performance testing of CPU floating-point operations, in particular to an automatic testing method for testing the performance of CPU floating-point operations applicable to various processor platforms. Background technique [0002] At present, in the CPU floating-point operation performance test, the industry mostly uses the manual installation Spec CPU and linpack test toolkit provided by Intel to examine the CPU floating-point operation test performance of each processor platform, but according to different configurations of different processor platforms, manual installation is required. l_mpi and l_commpxe toolkit, set test parameters. This increases the time, increases the cost of using human resources, and is extremely inefficient. Contents of the invention [0003] The present invention provides a method for automatically testing the performance of CPU floating-point operations, which is used to realize...
