[Daya and I work together, so some of this is for him]
The GPT Fault line is a change in the simulator, and other changes have been made in m5, yes, but they shouldn't affect output unless as the result of a fault injection. Daya, the warn and fatal messages sometimes show up after a fault injection - problems can propagate sometimes beyond just the internals (where we do the result check, etc), but I can't see a reason for them to show up otherwise in relation to our code. I would try this with a clean copy of m5 just to be sure to see if the benchmark still fails. -Griffin On Tue, 28 Jun 2011 18:00:06 -0500, Ali Saidi wrote: We run vortex nightly without any issues. vortex shouldn't be trying to use the socket() syscall as far as I know. Additionally, I don't know what code would print the, "GPT fault.." line as I can't find "GPT" in the source tree. Have you made any changes to the simulator? What compiler are you using?
