Hi all, We have got a fix, but for now I will commit a change that turns it into a warning instead of a fatal. I don't want Amin to have to rebase his patch (again) :-)

I have got that panic error a few times so far when the running application is memory-intensive with low temporal locality. I could not figure out why this panics, but I don't think they consider only first and last activations. A list of past X activations is kept, where X is the maximum number of allowed activations in a rolling window. The size of actTicks is always X. Anyway, I agree with you that this should be fixed, but if I understand you right, your solution does not work.

There is recordActivate (Tick act_tick) module In simple_dram.cc. In that module, gem5 did sanity check. It is true that in same DRAM device, it can't activate X times in tXAW. But gem5 do not care the number of activate operations, only consider first and last activation time. I think, it need to check the number of activation operations too. Like this, void SimpleDRAM::recordActivate(Tick act_tick) { ... // sanity check if ( actTick.size() == activationLimit-1) { if (actTicks.back() && (act_tick - actTicks.back()) < tXAW) { panic("Got %d activates in window %d (%d - %d) which is smaller " "than %d\n", activationLimit, act_tick - actTicks.back(), act_tick, actTicks.back(), tXAW); } } ... } Please help me. _______________________________________________ gem5-users mailing list gem5-users@gem5.org<mailto:gem5-users@gem5.org> http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users -- IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
