[mpich-discuss] Comparison among OpenMPI, MPICH2 and MSPICH on Windows

[bob ilgner]

Hi Hiral,

>From several years worth of deploying openMP and MPI on platforms my 2
cents worth is :

"Use openMP for suitable applications to give quick results and
reasonably good performance on low thread count < 16. Use MPI with
more effort yet get better performance and better large end
scalability. This is all with reference to numerically intensive
apps".
