Hello all,
I am having trouble in running Gaussian Accelerated MD (GaMD)in AMBER 16
(CUDA). Here is the error appeared:
-- cudaMemcpy GpuBuffer::Download failed an illegal memory access was
encountered
-------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status,
thus causing
the job to be terminated. The first process to do so was:
Process name: [[62583,1],0]
Exit code: 255

It seems that after the first step of GaMD, it halted.
I am not able to figure out why this is happening. Please help.
