Test code indeed would be helpful. You may get better warnings about context ID and/or communicator leaks if you configure a stock MPICH with "--enable-g=all". -Dave On Feb 23, 2013, at 7:05 PM CST, Jeff Hammond wrote:
It's 2048 in all MPICH2-derived implementations that I know about, including the ones used on BGP and BGQ.
Since I know what your issue is already, I think the problem has something to do with context id leaking. You should post your test code.

Hi,
What is the maximum number of communicators in the MPICH that is used on BG/P vs. that used on BG/Q?
