Hello All,
I am attempting to do some SMT experiments with multiple benchmarks in SE mode,
but am having some trouble passing options to the binaries. I have no problem
running multiple binaries that take no arguments (hello world), or a single
binary with an argument (SPEC gzip). But if I try to pass arguments with the -o
(options) flag to multiple binaries, both will run but the second binary does
not get its input.
I have tried several iterations of the syntax (quotes, no quotes, etc. ), and
also tried passing them with the -i (input) flag.
An example of what I am trying to do:
#!/bin/sh
build/X86/gem5.opt \
configs/example/se.py \
-I 10000000 \
-c ./SPECs/401.bzip2/src/benchmark;./SPECs/429.mcf/src/benchmark \
-o ./SPECs/401.bzip2/data/input.program;./SPECs/429.mcf/data/inp.in \
--cpu-type=DerivO3CPU --l1d_size=64kB --l1i_size=16kB --caches --smt
Based on the contents of se.py, it seems like the -c (options.cmd) flag and
the -o (options.options) flag evaluate together in the same manner:
workloads = options.cmd.split(';')
if options.input != "":
inputs = options.input.split(';')
if options.output != "":
outputs = options.output.split(';')
if options.errout != "":
errouts = options.errout.split(';')
if options.options != "":
pargs = options.options.split(';')
There is then a loop that pairs the arguments with the benchmarks.
Does anyone know the proper way to pass input data to multiple benchmark
binaries for SMT runs? I have failed to find example code for this. If there is
an alternative method for running SPECS with SMT, I would very much appreciate
your guidance.
Thank you for your time and help!
-Ryan
