How to use PIMProcess #14

Open m1chaelyeung opened 4 years ago

m1chaelyeung commented 4 years ago

I see PIMProcess is declared in pseudo_inst.cc, so how can I use this function in my program. Should I run my program in fs mode?

I have a similar question that there are two functions called "PIMProcess" and "HostProcess" in pseudo_inst.cc. Do you know how can I use them?

I have read the source code of PIMProcess and HostProcess. I only add PIMProcess into my own cpp code and compile it as kernel. Then I set up the parameters of my system and run gem5. But I got a segmentation fault during the runtime and I haven't solved it. parameters: ./build/X86/gem5.opt --debug-flags=PIM configs/example/se.py --cpu-type=TimingSimpleCPU --cpu-clock=1GHz --caches --l2cache --l1d_size=32kB --l1i_size=32kB --l2_size=2MB --l1d_assoc=4 --l1i_assoc=4 --l2_assoc=8 --enable-pim --pim-type=cpu --num-pim-processors=1 --coherence-granularity=64B -c ./tests/test-progs/pim-hello/hellopim running output: (pim_test.cpp) : Use PIM to calculate the sum of a and b 8329928000: system.cpu: Encountering PIMProcess command, use PIM processor [0] takeOverFrom-1 8329928000: system.cpu: SuspendContext 0 8329928000: system.pim_cpu: ActivateContext 0 warn: ClockedObject: Already in the requested power state, request ignored 8329978000: system.pim_cpu: inst is 1135751896167858944 gem5 has encountered a segmentation fault!
