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. Please do let me know if I am missing something. I am currently evaluating marss86 to see if I can use it for my research. So I am just playing around with the different features. Thanks for your help! Regards, Ankita On Fri, Sep 7, 2012 at 11:20 AM, Ankita (Garg) Goel <[email protected]>wrote: > Hi, > > I am new to marss86.
