Thanks for answering so quickly.
I am currently running the debug like you suggested but it is taking a
while. I wont know for some time, but the other reason it was not making sense
is that it will not run in detailed mode when i run both benchmarks, so i
cannot get IPC or any other info either; basically just about 30 lines of
non-essential stats versus about 600+. Not to mention --caches and --l2cache
missing as well. If i can manage to run each program on a different core it
would only be beneficial if the stats file is also right.
Thanks for the help,Dean

to run each
Also, if you want to make sure this is what happens, you can specify
"--debug-flag=Exec" before se.py to see the flow of instructions and you should
be able to see two different cpu in the output debug file. Then you can compare
this against running each benchmark alone on one core and see if the flow of
instructions matches.

I believe the se.py script is already setup such that the first program runs on
the first core while the second program run on the second core. Someone please
correct me if I'm wrong!!
If you look at se.py:
for i in xrange(np): if options.smt: system.cpu[i].workload =
multiprocesses elif len(multiprocesses) == 1: system.cpu[i].workload
= multiprocesses[0] else: system.cpu[i].workload = multiprocesses[i]
The last line should be the one that is invoked assuming you're not using SMT.
Basically the workload for cpu[i] gets assigned to multiprocess[i], where
multiprocess is a list which equals to [.../basicmath_small, ../search_small].

I have been in a research program for a few weeks, and am so close to
making a real breakthrough in my topic but ran into a few major issues. They
seemed simple at first. Here is what command I am running, most of it is just
the defaults but just to show it all stays constant when i add cores.
build/X86/gem5.opt configs/example/se.py -c
../benchmarks/automotive/basicmath/basicmath_small;../benchmarks/office/stringsearch/search_small
--clock=2GHz --num-cpus=2 --caches --l2cache --cpu-type=detailed
--l1d_size=64kB --l1i_size=32kB --l2_size=2MB --l3_size=16MB --l1d_assoc=2
--l1i_assoc=2 --l2_assoc=8 --l3_assoc=16 --num-dirs=1 --num-l2caches=1
--num-l3caches=1
The most important issue I have, put simply, is how to specify basicmath_small
to run on the first core, and search_small to run on the second. When I run
this it just runs them both successively on the first core, and stats output is
very limited. Definitely not the usual stats.txt ran in detailed mode. Once I
am passed this point, the next two weeks after should be very fulfilling and
productive. I look forward to your response.
Thank you,Dean_______________________________________________
