It seems that simulation is started, can you check what is printed in logfile?
Also regarding bzip.cfg file, dont specify simpoint information when you want to run simulations. If you want to run simulations from a checkpoint use something like below: -machine single_core -logfile sc.log -stats stats.txt -run -kill-after-run - Avadh On Fri, Sep 7, 2012 at 1:49 PM, Ankita (Garg) Goel <[email protected]>wrote: > Even running bzip2 without checkpoints, the simulation seems to freeze: > > $ ./start_sim ; <bzip2 with params> ; ./stop_sim ; > > The freeze occurs at: > > Completed 2726000 cycles, 1960176 commits: 482598 Hz, > 355575 insns/sec: rip ffffffff812a1825spec_init > Completed 67921000 cycles, 83616859 commits: 284637 Hz, > 359909 insns/sec: rip ffffffff8114e969 > > The stats do not seem to increase after this.
