Re: [gem5-users] FS-Run Multi thread application on Multi core

well, why don't you try tracing context switches happening on the CPUs? 

That can give you the clue of a thread index/context running on a cpu...

i.e., CPU index and thread index running on it.

Hi Tod
thank you very mush for help me.
No, I guess that "TO" equal with "Thread 0" . I want to trace CPU index and thread index running on it.  
thanks a lot.

Are you sure about "this T0 corresponds to 'thread 0' for your application"? I am not sure, sorry about it? lets see if somebody guides us...
I think your application should run fine. what exactly are you are trying to trace?

thank you for
because for example in short section of my trace only T0 exist for both of  cpu0 and cpu1. May i forget to do something else?

How do you know that there is only thread 0 and which trace file are you referring  to?

제목: [gem5-users] FS-Run Multi thread application on Multi core
Hi, all
I am using alpha fs mode.
I want to have an application with 2 threads running on 2 cpus. when i traced region of interest, only thread 0 exist in trace file. how can i run multi-thread application on mult-icore system?
this is my configuration that i run before got a checkpoint:

build/ALPHA/gem5.opt configs/example/fs.py --num-cpus=2 --caches --script=/home/sobhan/Desktop/gem5-script/blackscholes_2c_simsmall_ckpts.rcS

after got a checkpoint:

build/ALPHA/gem5.opt --debug-flags=Exec --debug-file=/home/sobhan/Desktop/blak.out configs/example/fs.py --cpu-type=detailed --num-cpus=2 --caches -r 1

please answer my question.
thanks
