Detailed Explanation

There are many combination to compile High Performance LINPACK (HPL) with different configurations such as different compiler, different basic linear algebra subprograms (BLAS), massage passing interface (MPI) libraries: for example

  • Which compiler + HPL + which Blas (OpenBLAS / Intel MKL / CuBLAS) + which MPI (OpenMPI, MPICH, Intel MPI)

In this post, we are going to use GNU compiler, OpenBLAS, OpenMPI for HPL-GPU

  • The build system is Intel Skylake CPU, 128GB Memory, Nvidia GPUs on Ubuntu 20.04
  • NVIDIA driver is ready and CUDA 12.0 has been installed and library can be found at /usr/local/cuda
  • We are using OpenMPI, OpenBlas and hpl-2.0_FERMI_v15 as a ingredient, gcc version 10, g++ version 10 and gfortran version 10
_version=v0.3.23
FILE=$_version.tar.gz 
wget http://github.com/xianyi/OpenBLAS/archive/$FILE
tar -xzvf $FILE
cd OpenBLAS-0.3.23
# OpenBLAS does not support f77, GCC or Intel are supported
# type make to detect the CPU automatically. or type make TARGET=xxx to set target CPU, e.g. make TARGET=NEHALEM. The full target list is in file TargetList.txt.
make 
# To install the library, you can run "make PREFIX=/path/to/your/installation install".
mkdir -p /opt/hpcmate/home/lib/OpenBLAS-0.3.23
make PREFIX=/opt/hpcmate/home/lib/OpenBLAS-0.3.23 install 
ls ~/lib/OpenBLAS-0.3.23/lib

now, compiled OpenBLAS's library and header file is available ~/lib/OpenBLAS-0.3.23


Best Practices

  • 최신 버전 사용 권장
  • 공식 문서 참고
  • 테스트 환경에서 먼저 검증
