运行 HPL¶
编译 BLAS/CBLAS¶
BLAS 为 fortran 接口的库，CBLAS 为 C 语言接口的库
tar zxf blas-3.8.0.tgz
tar zxf cblas.tgz
cd BLAS-3.8.0
make #生成blas_LINUX.a
cp blas_LINUX.a ../CBLAS
cd ../CBLAS
vi Makefile.in
#修改
# BLLIB = ../blas_LINUX.a
make #在lib/下生成cblas_LINUX.a
编译 HPL¶
tar zxf hpl-2.3.tar.gz
cd hpl-2.3
cp setup/Make.Linux_PII_CBLAS ./Make.<arch> #在top-level 文件夹下
vi Make.<arch> #修改
make <arch> #在bin/<arch>/下生成HPL.dat xhpl
Make.示例¶
OpenMPI+CBLAS¶
ARCH = <arch>
TOPdir = /home/mpiuser/hpl-2.3
MPdir = /path/to/OpenMPI
MPinc = -I$(MPdir)/include
MPlib = $(MPdir)/lib/libmpi.so
LAdir =
LAinc =
LAlib = path/to/cblas_LINUX.a path/to/blas_LINUX.a #顺序不能改变，cblas依赖blas
HPL_OPTS = -DHPL_CALL_CBLAS
CC = mpicc
LINKER = mpif77
HPL 优化¶
配置参数¶
计算次数：
\[
\#Ns \times \#NBs \times \#(Ps, Qs) \times \#PFACTs \times \#NBMINs \times \#BCASTs \times \#DEPTHs
