Hi Sasha,
I can report very similar experience on our system:
SuperMicro SYS-7046GT-TRF, single Intel Xeon X5650, 12GB RAM,
3x *NVIDIA GTX 470* from MSI (N470GTX M2D12),
CentOS 5.2 x86_64, gfortran 4.1.2-42,
nvcc 3.1, V0.2.1221, NVIDIA Driver 256.40,
Amber11 with bugfixes 1 to 7 applied, compiled with './configure -cuda
gnu' (SPDP by default).
I've been running the JAC NPT simulation using the inpcrd, prmtop, mdin
files provided by Ross in his September 8 post.
The jobs are repeatedly stopping, respectively after 95,000 steps (196
ps), 421,000 steps (848 ps), 53,000 steps (112 ps), 43,000 steps (92 ps)
with the same error message: "Error: the launch timed out and was
terminated launching kernel kPMEGetGridWeights".
