Can you provide a short test that reproduces the issue you are seeing? I will add a Trac ticket for it.

Hi,

I noticed that MPICH's MPI_Dims_create() fails with a floating point exception, if the number of processes is larger than 10^6. Apparently the reason is that the prime factors are hard coded into the code and are limited to 1000 (or sqrt(10^6)). Open MPI's implementation has no such limitation.
