Hi all,

Apologies for cross-posting, but I'm not quite sure where this problem lies. When running an IMD simulation using NAMD 2.10-CUDA (GTX970M card, for what it's worth), I find that if I use too many CPU cores (5-6 out of 8 total available) the simulation will inevitably crash after a few hundred steps with no error message. If I reduce the number of cores to 2-3 it runs stably.
