I am running a parallel MPI program running on
a Beowulf cluster system which writes some large files opened using STATUS=SCRATCH.
I wish to arrange that these are stored in a filesystem local to the node, such as /tmp, rather than an NFS-mounted file system for reasons of efficiency.
Where do STATUS=SCRATCH files get written by default? I could not find this information in any of the documentation. Second, is it possible to specify a location at compile- or run-time?
