Hi,
I am fairly new to gem5 as well but I managed to get this done by
reading through this thread
(http://www.digipedia.pl/usenet/thread/11778/1757/). You'll have to
change the se.py script to run different workloads in different cpu. I
am not sure what you mean by mesh technology though. Here is what I
did, I added an option in Options.py (config/common/) and then added
this code below the elif options.cmd case in se.py:
elif options.cmd:
process = LiveProcess()
process.executable = options.cmd
process.cmd = [options.cmd] + options.options.split()
multiprocesses.append(process)
elif options.multiprogram:
executable = ["hello", "dealII", "bzip2", "mcf"]
cmd_list = [["hello"], ["dealII"], ["bzip2", "bzip-input.gif"],
["mcf", "mcf.in" ]]
for num in xrange(4):
proc = LiveProcess()
proc.executable = executable[num]
proc.cmd = cmd_list[num]
multiprocesses.append(proc)
Quoting Tianyi Wang <[email protected]>:
Hi, all
I am new to gem5. Currently I want to do some experiments such that
a task-graph like application running on a multi-core platform. I
have read the latest tutorial and I am able to run some examples
shown in the video.
Using one example to be specific: hello world.
I run the script:
build/ALPHA/gem5.opt configs/example/se.py -c
tests/test-progs/hello/bin/alpha/linux/hello, and I got the result
with no problem.
My questions is if I want to run four "hello world" instances on
four different cores with mesh topology, how can I do that? I try to
use option --topology=Mesh, however, it seems that se.py didn't
support this option. Do I need to use some other scripts? Can anyone
help me with this problem or any suggestion/advice would be
appreciated?
Thanks,
Tianyi
