Dear MPI people,                                       I need a set of algorithms for calculating the same thing using different distributed (MPI) algorithms. The algorithms may need the different data distribution and their execution times are sensitive to the problem size, number of processe

Thank you! This is on my list to investigate; I'm sorry I haven't had a chance to look at it in detail yet. I hope to look at this in detail later this week. On May 21, 2012, at 4:06 PM, Orion Poplawski wrote: > On 05/15/2012 10:37 AM, Orion Poplawski wrote: >> See https://bugzilla.redhat.c

You haven't really stated what kind of algorithms you want, other than the fact that they need to be parallel. :-) Your best bet is Google. There's lots of high-quality MPI-based middleware out there such that you might not need re-invent the wheel. Good luck. On May 21, 2012, at 3:02 PM, M
