Hello all, I have tried to simulate single core ALPHA processor with SMT via SE mode. I would like to use fast-forward because SPEC is too long. However, it seems not to properly work with SMT.
When running the simulation, the error occurs like below. ------------------------------------------------------------------------------------------------------------------------------------------------ $] ./build/ALPHA/gem5.debug configs/example/se.py --num-cpus=1 --smt --cpu-type=detailed --caches -c 'bzip2;bzip2' --option="input.source 280;input.source 280" --maxinsts=10000000 --warmup-insts=1000000 --fast-forward=10000000 gem5 Simulator System. http://gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 compiled Nov 1 2013 18:28:12 gem5 started Nov 1 2013 21:56:01 gem5 executing on Arboretum command line: ./build/ALPHA/gem5.debug configs/example/se.py --num-cpus=1 --smt --cpu-type=detailed --caches -c bzip2;bzip2 --option=input.source 280;input.source 280 --maxinsts=10000000 --warmup-insts=1000000 --fast-forward=10000000 2GHz Global frequency set at 1000000000000 ticks per second *fatal: Workload Size (2) > Max Supported Threads (1) on This CPU* @ cycle 0 [create:build/ALPHA/cpu/o3/deriv.cc, line 46] Memory Usage: 623832 KBytes ------------------------------------------------------------------------------------------------------------------------------------------------ When I omit the fast-forward option, the simulation works well. Sure, the number of threads is two. I searched the issue in mailing list, but I could not find the solution. Is there anyone who has experience the related problem? Thank you ! - Jeongseob
