Hi,

I've had the same problem when submitting to grid-engine.

The fix is that you have to make sure that you are exporting the 
LD_LIBRARY_PATH environment correctly and that the libraries are 
available on the slave nodes in your cluster. Our master node exports 
some folders to the workers so in grid-engine I usually have to do 
something like.

export LD_LIBRARY_PATH <path to libs>:$LD_LIBRARY_PATH
./runjob

You can also use the -V flag (I think) in pbs to export paths.

If the folder that the libraries are in is not exported you'll either 
need to make sure that they are installed on the slave nodes or 
re-compile gromacs statically with the -static flag. This builds the 
libraries into the executable so they are not required to be loaded at 
runtime.

Hope this helps,

Campbell
