[gem5-users] gem5 processes

[Parmida Vahdatnia]

Hi all
I'm trying to run some processes in various mapping ways on a XY_Mesh in
gem5, for this I'm assigning each cpu in the mesh with a selected process
but till now I've only used the basic hello world in test-progs while I
want my processes to contain mathematical and other kind of work.
are there any other processes like the hello world that I can use in gem5?
and if not and if I should use benchmarks is there a way to break
benchmarks into tasks and assign each task to separated cpus in gem5?
thank you!

Also is there a way to tell a number of cpus to do nothing? I get an error
of list index when I don't assign any process to some of them in the se
code.

Hello again
the problem is kind of solved, if anyone else ever faced this you could
just write your own processes in c and give the compiled files to cores
instead of breaking benchmarks, Also for core communication you should bind
those processes together. And for the cores that I want to do nothing I'm
just assigning a compiled c code that does nothing to them although don't
know if that's ok to do.
