Basic Linear Algebra Subprograms testbench

Primary LanguageC

BLAS-testbench

A testbench of Basic Linear Algebra Subprograms.

Construction

  • HPL(The High Performance Linpack)
    • HPL.dat: the config file of HPL
    • Make.test: the makefile config to compile HPL
  • single_operator_test
    • Level-1.c: the level-1 testbench of BLAS
    • Level-2.c: the level-2 testbench of BLAS
    • Level-3.c: the level-3 testbench of BLAS

How to use

  • HPL

    1. Download and compile: Openmpi, gcc, gfortran

    2. Download and compile HPL

      • move make.test to HPL files

      • specify the path of make.test ((your optimized OpenBLAS / OpenMPI / HPL path) in make.test

      • bash:

        make arch=test

      • cd HPL/test/bin: config the HPL.dat and run

        mpirun -allow-run-as-root  -np 4 ./xhpl > result.txt

  • Single_operator_test

    1. Specify the dynamic link path of cblas.h (your optimized OpenBLAS) in every C code.

      #include "/root/openblas/pre_openblas/include/cblas.h"

    2. run the code
