Re: [gem5-users] Changing the "inParallelMode"
Hi, This work was started in past You can the progress information and steps required in this link http://www.m5sim.org/Parallel_M5 For now seeing the mailing I do not see anyone continuing this work, but there were people who had started working on this On Sun, Mar 1, 2020 at 2:25 AM YUCHEN ZHOU wrote: > Hi all, > > > > Recently I tried to parallelize the gem5's simulation engine to run on > shared-memory multicore systems.

[gem5-users] Changing the "inParallelMode"
Hi all, Recently I tried to parallelize the gem5's simulation engine to run on shared-memory multicore systems. I changed the value of "inParallelMode" to "true" in eventq.cc which I thought could be used to change the execution mode of gem5 and I changed the main.py, event.mainq = event.getEventQueue(0)--> event.mainq = event.getEventQueue(1) in order to generate two threads. Then I used gem5 to simultaneously two programs on a multi-core system, then I got a "core dump”. And I found in gem5/src/sim eventq_ impl:96 assert(!inParallelMode || this == curEventQueue()) failed. Might I know if there is something wrong with the way I changed the mode or the work about Parallelizing M5 is not fully completed? It would be appreciated if you could reply at your earliest convenience. Thank you!
