Hi,
I used:
/scratch/gpfs/yanqiz/temp/gem5/build/ALPHA/gem5.opt
--debug-flags=ExecAll,-ExecSymbol -- trace-file=trace_new.out
configs/example/fs.py --caches --l1i_size=8kB -- l1d_size=8kB
--cpu-type=detailed -n 4 -F 5000000000 --script=bodytrack_4c_simsmall.rcS
to run PARSEC multithread program with 4 threads and 4 cpus. But from the
generated trace, only cpu numbers differ, not the thread. The thread number is
always 0.
What is wrong here?
Thanks,

Hi,
I run it in FS mode. Can you tell me the correct command? For instance, I want
to run with 4 threads. Also I am curious whether the multithreading in gem5 is
deterministic...
Thanks,
Yanqi

heya,
What's your command to run the simulations? Did u run it in SE or FS? In SE
mode, u need to link the m5thread lib for multithread benchmarks like PARSEC.
In FS mode, u only need to link the lpthread (if u built the parsec pthread
version) and the OS will do all the context switches for u.
Also did u turn on any debug flags like ExecAll which prints all the
instructions including syscalls.

Hey everyone,
Has anyone ever run multithreading program in gem5, such as PARSEC? What
command should I use?
I set the cpu_num to 4, only the system cpu is different in the trace file. How
multithreading works in gem5? I cannot see any system call in the trace file,
when the threads do a context switch in gem5?
Thanks,
