linpack测试软件安装

Linpack安装过程

Linpack安装在安装之前，我们需要做一些软件准备，相关的软件及下载地址如下。

（1）Linux平台，最新稳定内核的Linux发行版最佳，可以选择Redhat,Centos等。

（2）MPICH2，这是个并行计算的软件，可以到

http:

//www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?

s=downloads

下载最新的源码包。

（3）Gotoblas，BLAS库（BasicLinearAlgebraSubprograms）是执行向量和矩阵运算的子程序集合，这里我们选择公认性能最好的Gotoblas，最新版可到http:

//www.tacc.utexas.edu/tacc-projects/下载，需要注册。

（4）HPL，linpack测试的软件，可在lib.org/benchmark/hpl/下载最新版本。

一、Mpich2的安装过程

1、解压软件包

tarzxvfmpich2-1.1.1p1.tar.gzcdmpich2-1.1.1p1

指定目录编译

./configure--prefix=/root/linpack/mpi--with-pm=smpd--enable-f77

make

makeinstall

2、配置环境变量

vim~/.bashrc

PATH="$PATH:

/usr/local/mpi/bin"

source.bashrc3、

测试环境变量

whichsmpd

whichmpicc

whichmpiexec

whichmpirun

下面这两部据说在测试时需要输入密码，但是不知道为什么这个密码没有生效。

4、修改/root/.mpd.conf

secretword=myword

chmod600/root/.mpd.conf

5、修改/etc/mpd.conf

secretword=myword

chmod600/etc/mpd.conf

6、测试mpich2的进程smpd是否启动

[root@LG01linpack]#whichsmpd

/root/linpack/mpi/bin/smpd

[root@LG01linpack]#smpd–s

[root@LG01linpack]#ps-ef|grepsmpd

测试mpi是否启动

[root@LG01linpack]#mpiexec-n1hostname

二、Gotoblas，BLAS库（BasicLinearAlgebraSubprograms）是执行向量和矩阵运算的子程序集合，这里我们选择公认性能最好的GotoblasGotoBLAS2-1.13_bsd.tar.gz

#tar-xzvfGotoBLAS2-1.13_bsd.tar.gz

#cdGotoBLAS2

#viMakefile.rule

改四个地方，标注为（#modified）的行：

进入目录执行：

./quickbuild.64bit

若出现如下：

../kernel/x86_64/gemm_ncopy_4.S:

192:

Error:

undefinedsymbol`RPREFETCHSIZE'inoperation../kernel/x86_64/gemm_ncopy_4.S:

193:

Error:

undefinedsymbol`RPREFETCHSIZE'inoperation../kernel/x86_64/gemm_ncopy_4.S:

194:

Error:

undefinedsymbol`RPREFETCHSIZE'inoperation../kernel/x86_64/gemm_ncopy_4.S:

195:

Error:

undefinedsymbol`RPREFETCHSIZE'inoperation

则执行：

gmakeclean

makeBINARY=64TARGET=NEHALEM

出现以上错误的原因为，cpu太新，配置文件不识别，需要重新指定一下CPU类型

三、安装HPL。

进入hpl文件夹从setup文件夹下cp与自己平台相近的Make.文件，复制到hpl文件夹内，比如我们的平台为Intelxeon，所以就选择了Make.Linux_PII_FBLAS，它代表Linux操作系统、PII平台、采用FBLAS库。

tarxzvfhpl-2.0.tar.gz

viMake.Linux_PII_FBLAS
