Previously i tried to execute NAMD on C870 card but it didn't work, it gives error "Charm++ fatal error:
FATAL ERROR: CUDA error allocating force table: feature is not yet implemented"
Now, I am using Tesla supercomputer desktop system with 4 Tesla C1060 card. And the motherboard is having nForce780a SLI graphics card. And i am not confirmed whether it is cuda enabled or not but my application i.e NAMD detect nForce 780a card and instead of running only on four C1060 cards it goes to nForce too.And when i tried to execute with one card it only goes to nForce780.
The command i give is like this:

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
mpirun has exited due to process rank 0 with PID 8486 on
node samir-desktop exiting without calling “finalize”. This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
And with two threads it detect one Tesla C1060 and nForce card…and give same error.
I want to know whether there is problem of memory with nForce card or it is not supporting CUDA or some other problem is there?
If anybody has done NAMD on any GPU card, let me know about that.
Thanks in advance.
