结果实例： 一个cpu的parsec结果

简介

限于篇幅限制，很多教程和论文只展示部分结果。我们这里展示非常细节的结果，包括输出的许多命令行结果。

运行命令行 的shell窗口

yzzzz42Checkpointing simulation…

yzzzzzz47oading old script…
#!/bin/sh

This is YZ’s modifed version of hack_back_ckpt.rcs originaly by Joel Hestness, hestness@cs.utexas.edu.

#I modified it to be able to run with new different script after restoring from a checkpoint.
#The key idea is to “m5read file” twice and “bash” rather than “exec” the script

Demo econd new script: cd /home/gem5/parsec-benchmark; source env.sh; parsecmgmt -a run -p blackscholes -c gcc-hooks -i simsmall -n 2; sleep 5; m5 exit;

You should observe via m5term 3456: First: old script, showing the content of this scipt. Second: new script, show the contents of cd /home/gem5/parsec-benchmark; source env.sh; parsecmgmt -a run -p blackscholes -c gcc-hooks -i simsmall -n 2; sleep 5; m5 exit;

分析：

概况

stats.txt里是4570s，也就是76分钟，用的cputype是timing simple。如果用kvm只需要几秒。

分析窗口 1

在命令行窗口 1 里 显示了“ Entering event queue @ 11769812739000. Starting simulation…”，这里意味着checkpoint （在这里是11769812739000 ticks）之前的仿真被跳过。
Exiting @ tick 143338763627000 because m5_exit instruction encountered 代表 143338763627000时收到了 m5 exit 命令，仿真结束。

分析窗口2

自带的开头

下面是我的脚本内容。我的脚本script会读取m5readfile 两次，下面是第一次的脚本内容

yzzzz42Checkpointing simulation...
yzzzz44CheckpointingDone
yzzzzzz47oading old script...
。。。。跳过一些
sleep 3; 
/sbin/m5 exit

下面是第二次的内容，第二次的内容是我–script指定的，与checkpoint时指定不同的脚本文件，内容如下/

yzzzzzz54oading second new script...
cd /home/gem5/parsec-benchmark; source env.sh;  echo " YZZZ source done ";  parsecmgmt -a run -p blackscholes  -c gcc-hooks -i simsmall  -n 1; sleep 5; m5 exit; 

我的脚本会cat这两个内容，还是执行(bash) 这个新的脚本文件的内容。
也就是说，我的脚本会让gem5运行一个bash，跳入 /home/gem5/parsec-benchmark路径，这个路径是disk自带的。然后source当前路径下的一个文件，env .sh,这也是disk自带的。 然后shell print一个我自定义的字符串，是为了检查这个脚本有在运行。然后是运行这个disk自带的benchmark，运行完后等待一会，退出。

下面可以看出，我的echo " YZZZ source done "有成功运行，接下来的漫长等待（1小时）就不担心了。

然后是 parsecmgmt -a run -p blackscholes -c gcc-hooks -i simsmall -n 1的结果。
这个很慢，地球时间需要一些时间。运行完成后的结果是：

至此，两个命令行窗口的全部结果都显示完了。
