SPEC CPU2006的编译和运行

SPEC，全称Standard Performance Evaluation Corporation。官网为https://www.spec.org

前期准备

安装编译器

安装本地编译器gcc-4.9、g++-4.9以及gfortran-4.9

1 2	# 逗号左右不能有空格 apt install -y {gcc,g++,gfortran}-4.9

查看gcc的安装位置：

[root@hgs ~]# which {gcc,g++,gfortran}-4.9
/usr/bin/gcc-4.9
/usr/bin/g++-4.9
/usr/bin/gfortran-4.9

也可以使用源码安装，具体参看通过源码安装GCC。

安装交叉编译工具

1	apt install -y {gcc,g++,gfortran}-4.9-aarch64-linux-gnu

查看安装位置：

[root@hgs ~]# which aarch64-linux-gnu-{gcc,g++,gfortran}-4.9
/usr/bin/aarch64-linux-gnu-gcc-4.9
/usr/bin/aarch64-linux-gnu-g++-4.9
/usr/bin/aarch64-linux-gnu-gfortran-4.9

注意安装时和使用时的区别：安装时gcc在库名的开头，使用时gcc在命令的结尾。

SPEC CPU2006环境

1.下载SPEC CPU2006（目前，SPEC CPU2006需要付费下载）

2.解压

[root@hgs ~]# mkdir spec2006
[root@hgs ~]# tar -jxf cpu2006.tar.bz2 -C spec2006
[root@hgs ~]# cd spec2006

3.执行安装脚本

[root@hgs spec2006]# ./install.sh

SPEC CPU2006 Installation

Top of the CPU2006 tree is '/home/spec2006'

These appear to be valid toolsets:

linux-suse101-i386            For 32-bit i386 Linux systems.
tail: cannot open '+2' for reading: No such file or directory
==> /home/spec2006/tools/bin/linux-suse101-i386/description <==
For 32-bit i386 Linux systems.
                              Built on SuSE Linux 10.1 with 
                              gcc V4.1.0 (SUSE Linux)

linux-suse101-AMD64           For 64-bit AMD64 Linux systems.
tail: cannot open '+2' for reading: No such file or directory
==> /home/spec2006/tools/bin/linux-suse101-AMD64/description <==
For 64-bit AMD64 Linux systems.
                              Built on SuSE Linux 10.1 with 
                              gcc V4.1.0 (SUSE Linux)
                              Should also be usable on 64 bit EM64T systems

linux-redhat62-ia32           For x86-based Linux systems with GLIBC 2.1.3+
tail: cannot open '+2' for reading: No such file or directory
==> /home/spec2006/tools/bin/linux-redhat62-ia32/description <==
For x86-based Linux systems with GLIBC 2.1.3+
                              Built on RedHat 6.2 with gcc 2.95.3


Enter the architecture you are using:

这里输入linux-suse101-i386：

linux-suse101-i386


Checking the integrity of your source tree...


Checksums are all okay.
Removing previous tools installation
Unpacking binary tools for linux-suse101-i386...
Checking the integrity of your binary tools...

Checksums are all okay.
Top of SPEC benchmark tree is '/home/spec2006'
Everything looks okay.  cd to /home/spec2006,
source the shrc file and have at it!

修改配置文件

1 2	[root@hgs spec2006]# cd config/ [root@hgs config]# cp linux32-i386-gcc42.cfg qemurio-x86.cfg

4.设置环境变量

1	[root@hgs spec2006]# source shrc

之后，就可以使用SPEC提供的各种工具了，比如runspec等。

Integer Benchmark

整数测试

本地编译

1	[root@hgs spec2006]# runspec -a build -c qemurio-x86.cfg -i ref --tuning=base int

运行结果：

Build errors: 483.xalancbmk(base)
Build successes: 400.perlbench(base), 401.bzip2(base), 403.gcc(base), 429.mcf(base), 445.gobmk(base), 456.hmmer(base), 458.sjeng(base), 462.libquantum(base), 464.h264ref(base), 471.omnetpp(base), 473.astar(base), 999.specrand(base)

查看错误信息：

FormatterToHTML.cpp:139:42: error: 'memset' was not declared in this scope
  memset(m_charsMap, 0, sizeof(m_charsMap));
                                          ^
specmake: *** [FormatterToHTML.o] Error 1
Error with make 'specmake build': check file '/home/spec2006/benchspec/CPU2006/483.xalancbmk/run/build_base_qemurio.0000/make.err'
  Error with make!
*** Error building 483.xalancbmk

原因分析：FormatterToHTML.cpp使用了string.h中的memset函数，但是在编译时找不到“memset”。因此，需要在g++中添加编译参数-include cstring。

1 2	CC = /usr/bin/gcc-4.9 CXX = /usr/bin/g++-4.9 -include cstring

运行

1	[root@hgs spec2006]# runspec -a run -c qemurio-x86.cfg -i ref --tuning=base int

使用ARM64交叉编译

修改配置文件中的编译器CC

1	CC = /usr/bin/aarch64-linux-gnu-gcc-4.9

错误分析：

410、416、434、435、436、437、454的问题为

1	specmake: /usr/local/gcc42-0715-32/bin/gfortran: Command not found

3

[root@hgs spec2006]# apt install -y gfortran-4.9
[root@hgs spec2006]# which gfortran-4.9

并修改配置文件中的FC值：

1 2	# FC = /usr/local/gcc42-0715-32/bin/gfortran FC = /usr/bin/gfortran-4.9
