Hi Nilay,
Thanks for your answer. I was able to successfully run queens benchmark by
using se.py under examples. My command was;
-----------------------------------------------------------------------------------------------------
./build/X86/gem5.opt --debug-flags=Cache --trace-file=my_trace.out
configs/example/se.py -c tests/testprogs/queens/bin/x86/linux/queens -o "-c
8" --caches --l2cache \--cpu-type=timing
-----------------------------------------------------------------------------------------------------
Now I have modified common/Options.py and se.py to have 2 processors. I
have manually added 2 processes. In se.py, I have modified benchmarks part
like this;
-----------------------------------------------------------------------------------------------------
if options.benchmark:
workload1 = "tests/test-progs/queens/bin/x86/linux/queens"
workload1_args = "-c 8"
workload2 = "tests/test-progs/hello/bin/x86/linux/hello"
process1 = LiveProcess()
process1.executable = workload1
process1.cmd = [workload1] + workload1_args.split()
process1.output = "m5out/p1.txt"
print "process1.cmd: ", process1.cmd
process2 = LiveProcess()
process2.executable = workload2
process2.cmd = [workload2]
process2.output = "m5out/p2.txt"
multiprocesses.append(process1)
multiprocesses.append(process2)
-----------------------------------------------------------------------------------------------------
When I run 2 queens benchmark with different parameters, it's ok. But when
I run 1 queens and 1 hello as above, I cannot see queens finishing in
output files. But hello does before simulation terminates. Is there
something I am missing?
Console;
-----------------------------------------------------------------------------------------------------
./build/X86/gem5.opt --debug-flags=Cache --trace-file=my_trace.out
configs/example/WithOptionParser.py -b --caches --l2cache \--cpu-type=timing
-----------------------------------------------------------------------------------------------------
In output I normally have only 2 unimplemented instruction warning because
of queens benchmark. But it gives 4 when I run hello and queens together.
Why does this happen ?
Output;
