Subject: [OMPI users] MPI_TYPE_MAX

Hi All,

I keep getting an error about running out of MPI_TYPE_MAX and needing to set the environment variable higher. What is this, and why is it happening? All of the types and groups, etc that I create during my programs run are freed at the appropriate times. Making this number 10x bigger gets me about 10x more iterations..and I heard someone say to just set it to a huge number, but I hate doing stuff like that blindly.
