I think "-bpwarm:cores" is the number of cores per bpwarm unit, which should be "1" all the time. As suggested in
FLEXUS_INSTANTIATE_COMPONENT_ARRAY( BPWarm, theBPWarmCfg, theBPWarm, SCALE_WITH_SYSTEM_WIDTH, MULTIPLY, 1); There is one bpwarm unit for each core. To change the number of cores, you may need to change $num_cpus in prepare-benchmark-arch.simics for trace simulation. For timing simulation, you will have to change more, including L2, nic, net-mapper, etc. All these are based on my experience. Since I am not an expert in this, please double check these...
