Hello Matheus, sorry I was a bit busy today :) For my model Ive only simulated a single core. I am intressted in the accesses of the register file to forecast its reliability.
For the parsec benchmarks you need to select a kernel that has at least the version which is provided by http://www.cs.utexas.edu/~cart/parsec_m5/ Hope this helps :) Best regards, Chris 2014-11-25 9:37 GMT+01:00 Matheus Alcântara Souza <[email protected]>: > Hello, > > How many (I mean, up to) cores did you try to simulate over this right > kernel? > > Thank you! > Matheus Alcântara Souza > > Em 24/11/2014, às 22:07, Christian List via gem5-users < > [email protected]> escreveu: > > Hello Andreas > Thank you for your fast response!
