I think I'm not running out of memory as i could run 16 total benchmarks too, like 16 core 1 thread.I get problem when number of threads increase like 2 core 8 threads, 4 core 4 threads, .... > > > On Wed, Jul 29, 2009 at 1:14 AM, Devraj Chapagain<[email protected]> > wrote: > > Hi, > > I am testing simulations using SPEC CPU 2006 benchmarks in newly updated > M5 > > (using hg clone http://repo.m5sim.org/m5 newm5 ) in SE mode.
