[mpich-discuss] Hypre solvers and MPICH

[Ryan Crocker]

Hi all, 

I had posted a thread before about getting a "too many communicators" error after a long run.   After going through with totalview i didn't see any problems.  I am using Hypre in MPI as a Poission solver.  I think this is probably causing the error because i need to create and destroy multiple Hypre solver constructs during my run (at almost every iteration) .  Does anyone know enough about Hypre coupled with MPICH to know if Hypre frees all the communicators when it destroys the constructs?  I looked over the hypre message board but it's pretty dead, i was wondering if i'll have better luck here.
