Hi,
Thanks for reporting this. I can reproduce the segfault but don't have an
explanation other than some interference between CUDA and the IMD sockets
connection. The following config file options seem to make it go away:
noPatchesOnZero yes
noPatchesOnOne yes

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.
