Most of the times, Mathematica gives the following error for the jobs submitted on multiple nodes in queue:
MathLink could not create temporary directory /tmp/MathLink: file exists The program may not function correctly
MathLink could not create temporary directory /tmp/MathLink: file exists The program may not function correctly
.....multiple times.
But the same program does not give this error if submitted on a single node.
Kindly help.
