Hi,
someone was talking abt core 2 duo performance on os x in some previous email. it seems that due to memory issues, it's not possible to get 2x the performance. there's also some mention of amd vs intel dual core.
for computation using PETSc, is there any reason to buy one instead of the other? Also, supposed I use winxp + mpich2 + PETSc on a dual core, what sort of performance increase can we expect as compared to PETSc + nompi on the same machine?
or is that too difficult an answer to give since there are too many factors?
thank you
regards
