Hi, I've been trying to simulate Parsec benchmarks in smt (multiple threads in each core). Referencing this: https://www.mail-archive.com/search?l=gem5-users@gem5.org&q=subject:%22%5C%5Bgem5%5C-users%5C%5D+Running+full+system+with+SMT%22&o=newest , in the file src/cpu/BaseCpu.py, I modified the line: numThreads = Param.Unsigned(1, "number of HW thread contexts") to have 3 threads. numThreads = Param.Unsigned(3, "number of HW thread contexts")
command line: ./build/X86/gem5.opt configs/example/fs.py --cpu-type=DerivO3CPU --caches --smt --disk-image=$M5_PATH/disks/linux-bigswap2.img --kernel=$M5_PATH/binaries/x86_64-vmlinux-2.6.28.4-smp --script=/home/user/boot/hellotest.rcS But I get--> fatal: fatal condition interrupts.size() != numThreads occurred: CPU system.cpu has 3 interrupt controllers, but is expecting one per thread (1) This indicates numThreads=1. Is this the right way to configure system for smt? Where else do I need to modify to get smt working in full system? Thanks
