Hi gromacs users,

  I'm running a simulation but I keep getting the following errors.

rogram mdrun_mpi, VERSION 4.5.1
Source code file: gmxfio.c, line: 537

Can not open file:

"That Was Cool" (Beavis and Butthead)

Error on node 0, will try to stop all the nodes
Halting parallel program mdrun_mpi on CPU 0 out of 4
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.

gcq#182: "That Was Cool" (Beavis and Butthead)

mpirun has exited due to process rank 0 with PID 9680 on
node compute-0-10 exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

 I don't know why gromacs cannot find my taExcited.tpr file, since it does exist in my working directory. However I noticed that when gromacs makes copies of my log files, its putting it in my home directory. This leads me to believe that it must be looking into the wrong path. This problem is only recent since gromacs knows where to looking when i reference my other working files, such as when i run grompp, but mdrun does not want to open up my .tpr file. Any ideas?
