Hi,
Is there a way in PETSc 2.3.3-p15 to force the order of operations in parallel so results do not vary from run to run on more than two processors? I did look in the archives and saw -vecscatter_reproduce but it was not clear to me if this is the only place where out of order operations can occur due to communications. For example can it happen during matrix assembly if 16 processors add to the same rows in the matrix? Thanks for your help, Harun Bayraktar -------------- next part -------------- An HTML attachment was scrubbed...
