<div>Hi,</div>
<div> </div>
<div>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.
</div>
<div> </div>
<div>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?
</div>
<div> </div>
<div>or is that too difficult an answer to give since there are too many factors?</div>
<div> </div>
<div>thank you</div>
<div> </div>
<div>regards</div>
