Hi,

I'm using an "ibverbs" version of charmrun to initiate parallel execution of NAMD. Charmrun aborts for more than 1024 processes. I have set ++batch 8. When I set ++batch 16, charmrun aborts for any number of processes. I have tried ++maxrsh 16 and ++maxrsh 32, as well as ++timeout 2, with no effect.

Any ideas how I can initiate parallel execution for more than 1024 processes?

Thanks,

Russ Brown
