Hi Pushkar,
According to my experience, you should create new liveprocess for each
(same) executive file. You can first use different benchmarks to see
whether the problem (segmentation fault) is still there. If not, then
you can come back to this special simulation: create new (empty)
liveprocess in se.py and assign the same RADIX to each process so that
gem5 treat them as completely different ones. Let me know if it doesn't
work. (maybe you can attach your modified se.py)

Nilay,
If you are using the same se.py that comes with the gem5, if there is
only one workload specified, All the system.cpu[i].workload is
assigned the same process.
However if I use the same se.py specifying the -c
"splash2/codes/kernels/radix/RADIX;splash2/codes/kernels/radix/RADIX;splash2/codes/kernels/radix/RADIX;splash2/codes/kernels/radix/RADIX"
it says
fatal: Can't load object file
splash2/codes/kernels/radix/RADIX;splash2/codes/kernels/radix/RADIX;splash2/codes/kernels/radix/RADIX;splash2/codes/kernels/radix/RADIX
This is because the split using ';' occurs only for finding the num of
threads in the se.py. The
"splash2/codes/kernels/radix/RADIX;splash2/codes/kernels/radix/RADIX;splash2/codes/kernels/radix/RADIX;splash2/codes/kernels/radix/RADIX"
gets assigned as one workload for all the CPUs,
Hence I modified the file so that the command line is split with ';'
and the different workloads are assigned to different cpus. However, I
get the following at terminal
Segmentation fault (core dumped)
any insights on this??
am i missing any trick here. Let me know if you want me to attach the
modified se.py here.
Thanks,
