gem5中运行spec2006

问题来源：为了模拟和测试cpu架构的性能，故摸索了下gem5下如何运行spec2006的。

步骤一 (编译spec2006)：
1. 购买或下载spec2006源码；
2. 参考Docs/install-guide-unix.html中的方法安装，进入spec2006目录，执行 ./install.sh，然后选择y执行；
3. 执行 . ./shrc (注意是点，空格，点，斜杠shrc。此为bash编译系统)；
4. 测试是否安装成功。runspec –config=macosx-ia32-iccifortv91.cfg –action=build –tune=base bzip2；
5. 看到提示成功信息即可，现在可在benchspec/CPU2006/401.bzip2/目录下看到生成的文件；

为了使spec在alpha架构下运行，需要进行交叉编译(已经预编译好的交叉工具链gcc-4.3.2,glibc-2.6.1(NPTL,x86/32),gcc-4.3.2, glibc-2.6.1 (NPTL,x86/64))：
1.在spec/configs/下复制一份副本cp linux32-i386-gcc42.cfg my-alpha.cfg
2.修改编译环境：

For example:CC =  /home/mjwu/crosstool/gcc-4.1.0-glibc-2.3.6/alpha/bin/alpha-gcc CXX = /home/mjwu/crosstool/gcc-4.1.0-glibc-2.3.6/alpha/bin/alpha-g++ FC =  /home/mjwu/crosstool/gcc-4.1.0-glibc-2.3.6/alpha/bin/alpha-gfortran# gem5下运行spec需要静态编译的，而默认是动态编译需加上static
default=base=default=default:
COPTIMIZE     = -O2 -static
CXXOPTIMIZE  = -O2 -static
FOPTIMIZE    = -O2 -static

3.生成二进制文件：

runspec --config=my-alpha.cfg --size=ref --noreportable --tune=base --iterations=1 bzip2

4.基于alpha体系结构的测试集就准备好了，下一步就是在gem5中运行。

步骤二(gem5中运行spec2006)：
说明：通常在gem5中以se模式运行spec2006，基本上已经足够运行，很少有人在fs模式下运行。因为spec2006是单线程，cpu内存密集型测试集。参考：mailing list的说明

以下步骤参考：tutorial-easily-running-spec-cpu2006-benchmarks-in-the-gem5-simulator
1.在gem5/configs/example/目录下复制se.py；

cp se.py spec06_se.py

2.在spec2006.py第一行中加入：

import spec06_benchmarks

3.增加benchmark的选项：

parser = optparse.OptionParser()
Options.addCommonOptions(parser)
Options.addSEOptions(parser)#在后面加入下面几行选项
parser.add_option("-b", "--benchmark", type="string", default="", help="The SPEC benchmark to be loaded.")
parser.add_option("--benchmark_stdout", type="string", default="", help="Absolute path for stdout redirection for the benchmark.")
parser.add_option("--benchmark_stderr", type="string", default="", help="Absolute path for stderr redirection for the benchmark.")

4.找到multiprocesses = []将其注释掉，当作单线执行，因为spec2006的所有测试集都是单线程的应用程序。

# multiprocesses = []
numThreads = 1

5.在numThreads = 1下加入如下内容：

#增加如下选项信息
if options.benchmark:print 'Selected SPEC_CPU2006 benchmark'if options.benchmark == 'perlbench':print '--> perlbench'process = spec06_benchmarks.perlbenchelif options.benchmark == 'bzip2':print '--> bzip2'process = spec06_benchmarks.bzip2elif options.benchmark == 'gcc':print '--> gcc'process = spec06_benchmarks.gccelif options.benchmark == 'bwaves':print '--> bwaves' process = spec06_benchmarks.bwaveselif options.benchmark == 'gamess':print '--> gamess' process = spec06_benchmarks.gamesselif options.benchmark == 'mcf':print '--> mcf' process = spec06_benchmarks.mcfelif options.benchmark == 'milc':print '--> milc' process = spec06_benchmarks.milcelif options.benchmark == 'zeusmp':print '--> zeusmp' process = spec06_benchmarks.zeusmpelif options.benchmark == 'gromacs':print '--> gromacs' process = spec06_benchmarks.gromacselif options.benchmark == 'cactusADM':print '--> cactusADM' process = spec06_benchmarks.cactusADMelif options.benchmark == 'leslie3d':print '--> leslie3d' process = spec06_benchmarks.leslie3delif options.benchmark == 'namd':print '--> namd' process = spec06_benchmarks.namdelif options.benchmark == 'gobmk':print '--> gobmk' process = spec06_benchmarks.gobmkelif options.benchmark == 'dealII':print '--> dealII' process = spec06_benchmarks.dealIIelif options.benchmark == 'soplex':print '--> soplex' process = spec06_benchmarks.soplexelif options.benchmark == 'povray':print '--> povray' process = spec06_benchmarks.povrayelif options.benchmark == 'calculix':print '--> calculix' process = spec06_benchmarks.calculixelif options.benchmark == 'hmmer':print '--> hmmer' process = spec06_benchmarks.hmmerelif options.benchmark == 'sjeng':print '--> sjeng' process = spec06_benchmarks.sjengelif options.benchmark == 'GemsFDTD':print '--> GemsFDTD' process = spec06_benchmarks.GemsFDTDelif options.benchmark == 'libquantum':print '--> libquantum' process = spec06_benchmarks.libquantumelif options.benchmark == 'h264ref':print '--> h264ref' process = spec06_benchmarks.h264refelif options.benchmark == 'tonto':print '--> tonto'process = spec06_benchmarks.tontoelif options.benchmark == 'lbm':print '--> lbm'process = spec06_benchmarks.lbmelif options.benchmark == 'omnetpp':print '--> omnetpp'process = spec06_benchmarks.omnetppelif options.benchmark == 'astar':print '--> astar'process = spec06_benchmarks.astarelif options.benchmark == 'wrf':print '--> wrf'process = spec06_benchmarks.wrfelif options.benchmark == 'sphinx3':print '--> sphinx3'process = spec06_benchmarks.sphinx3elif options.benchmark == 'xalancbmk':print '--> xalancbmk'process = spec06_benchmarks.xalancbmkelif options.benchmark == 'specrand_i':print '--> specrand_i'process = spec06_benchmarks.specrand_ielif options.benchmark == 'specrand_f':print '--> specrand_f'process = spec06_benchmarks.specrand_felse:print "No recognized SPEC2006 benchmark selected! Exiting."sys.exit(1)
else:print >> sys.stderr, "Need --benchmark switch to specify SPEC CPU2006 workload. Exiting!\n"sys.exit(1)# Set process stdout/stderr
if options.benchmark_stdout:process.output = options.benchmark_stdoutprint "Process stdout file: " + process.output
if options.benchmark_stderr:process.errout = options.benchmark_stderrprint "Process stderr file: " + process.errout

6.注释掉gem5自带的benchmark；

#自带的测试集
# if options.bench:
#     apps = options.bench.split("-")
#     if len(apps) != options.num_cpus:
#         print "number of benchmarks not equal to set num_cpus!"
#         sys.exit(1)
#
#     for app in apps:
#         try:
#             if buildEnv['TARGET_ISA'] == 'alpha':
#                 exec("workload = %s('alpha', 'tru64', '%s')" % (
#                         app, options.spec_input))
#             elif buildEnv['TARGET_ISA'] == 'arm':
#                 exec("workload = %s('arm_%s', 'linux', '%s')" % (
#                         app, options.arm_iset, options.spec_input))
#             else:
#                 exec("workload = %s(buildEnv['TARGET_ISA', 'linux', '%s')" % (
#                         app, options.spec_input))
#             multiprocesses.append(workload.makeLiveProcess())
#         except:
#             print >>sys.stderr, "Unable to find workload for %s: %s" % (
#                     buildEnv['TARGET_ISA'], app)
#             sys.exit(1)
# elif options.cmd:
#     multiprocesses, numThreads = get_processes(options)
# else:
#     print >> sys.stderr, "No workload specified. Exiting!\n"
#     sys.exit(1)############ 同时注释掉如下内容，因为是单线程：############
# for i in xrange(np):
#     if options.smt:
#         system.cpu[i].workload = multiprocesses
#     elif len(multiprocesses) == 1:
#         system.cpu[i].workload = multiprocesses[0]
#     else:
#         system.cpu[i].workload = multiprocesses[i]
#
#     if options.fastmem:
#         system.cpu[i].fastmem = True
#
#     if options.simpoint_profile:
#         system.cpu[i].simpoint_profile = True
#         system.cpu[i].simpoint_interval = options.simpoint_interval
#
#     if options.checker:
#         system.cpu[i].addCheckerCpu()
#
#     system.cpu[i].createThreads()

7.在上面注释后面添加如下内容：

#因为是单线程的,直接将该测试集给处理器就可以了
for i in xrange(np): system.cpu[i].workload = process print process.cmd

8.到此为止，spec06_se.py修改完成。

接下来创建spec06_benchmarks.py文件：
1.创建该文件：

touch gem5/configs/example/spec06_benchmarks.py

2.将如下代码复制到该文件中，如下文件采取了一个benchmark一个input，且都使用了第一个 reference input，如果有不同的需求，那么请根据自己的情况修改对应的内容。

3.到目前为止， gem5不知道spec二进制文件和input在哪里，那么现在通过下面的脚本配置运行环境。先建立脚本文件：

cd gem5
touch run_gem5_alpha_spec06_benchmark.sh

将如下内容粘贴到上面的脚本中：

#!/bin/bash
#
# run_gem5_alpha_spec06_benchmark.sh

4.根据自己的需求修改好上述文件后，只需执行下面的代码即可在gem5中运行spec。

cd gem5
./run_gem5_alpha_spec06_benchmark.sh <BENCHMARK_NAME> <FULL_PATH_TO_OUTPUT_DIRECTORY>

5.修改完成，开始测试。

测试：
1.为了验证和调试上面代码的有效性，使用如下命令测试：

build/ALPHA/gem5.opt --outdir=m5out/spec/ configs/example/spec06_se.py --benchmark=bzip2 --benchmark_stdout=m5out/spec/bzip2.out --benchmark_stderr=m5out/spec/bzip2.err --caches --l1i_size=32kB --l1d_size=32kB --l2cache --l2_size=4MB

通过上述命令测试可以调试spec06_benchmark.py和run_gem5_alpha_spec06_benchmark.sh中路径配置及测试集名称是否正确等。上述运行成功并有统计结果stats.txt即可。
