I've seen this error message in some old posts in the list archives, but
the solutions do not seem to work for me. When trying to run NAMD on a
NVIDIA Quadro 600 in a single machine (running Red Hat Enterprise Linux
6.4), with the command "./namd2 +p2 +idlepoll production.conf >
production.log" I get the following error:
=======================================================
------------- Processor 6 Exiting: Called CmiAbort ------------
Reason: FATAL ERROR: CUDA error on Pe 1 (server device 0): All CUDA devices
are in prohibited mode, of compute capability 1.0, or otherwise unusable.
Segmentation fault (core dumped)
=======================================================
Running "nvidia-smi -q" returns that Compute Mode is Default, and the
model has compute capability 2.1, so I really don't know what may be wrong.
I tried running some of those sample programs at
/usr/local/cuda-5.5/samples/ and they seem to be working fine. "matrixMul"
for example returns:
===============================================
[Matrix Multiply Using CUDA] - Starting...
GPU Device 0: "Quadro 600" with compute capability 2.1
MatrixA(320,320), MatrixB(640,320)
Computing result using CUDA Kernel...
done
Performance= 26.76 GFlop/s, Time= 4.899 msec, Size= 131072000 Ops,
WorkgroupSize= 1024 threads/block
Checking computed result for correctness: Result = PASS
Note: For peak performance, please refer to the matrixMulCUBLAS example.
===============================================
So it seems the system recognizes the card and can run programs on it, but
something is preventing NAMD to do it. What may be wrong?
