Hello All:
Please help me out here.
I am able to run bzip2 on a single core, but when I use -n 4 option to enable 4
core run with multiple copies of bzip2 in different cores, the stats are taking
CPU0-3 but nothing gets printed on CPU1 - 3. Could anyone help here on what the
issue is? The example run below has got -n 2
Here is my command: & the results:
/home/sasethur/gem5/gem5/build/ALPHA/gem5.opt
--outdir=/home/sasethur/gem5/gem5/out
/home/sasethur/gem5/gem5/configs/example/spec06_config.py -n 2 --caches
--cpu-type=detailed --mem-size=16GB --mem-type=dramsim2 -b bzip2-bzip2
--benchmark_stdout=/home/sasethur/gem5/gem5/out/bzip2.out
--benchmark_stderr=/home/sasethur/gem5/gem5/out/bzip2.err --l2cache
--l1d_size=32kB --l1i_size=32kB --l1d_assoc=8 --l1i_assoc=8 --l2_size=2MB
--l2_assoc=16 --l3_size=8MB -I 10000000 --warmup-insts=50000
-b bzip2-bzip2 -- if I give this way for multiple copies its not recognizing
the workload.
hence i just gave -b bzip2 that works, but no output in cpu1-3.
Here is the result:
Selected SPEC_CPU2006 benchmark

Please let me know how to resolve this issue to get the bzip2 running on the
second core?
