     236=== Working Area on Torque WNs ===
     237
     238By default, QWG templates configure Torque client on WNs to define environment variable `TMPDIR` and location of `stdin`, `stdout` and `stderr` to a directory local to the worker node (`/var/spool/pbs/tmpdir`) and define environment variable `EDG_WL_SCRATCH` to `TMPDIR` (except for jobs requiring several WNs, e.g. MPI). This configuration is particularly adapted to shared home directories but works well with non shared home directories too.
     239
     240The main requirement is to appropriatly size `/var` on the WNs as jobs sometimes require an important scratch area. On the other hand, `/home` is not required to be very large, as it should not store very large file for a long period. It is strongly recommended to use shared home directories, served through NFS or another distributed file system, as it optimizes `/home` usage and allows to dedicate local disk space on WNs to `/var`.
     241
     242If your configuration cannot be set as recommended or if you current configuration has a large space in /home and a limited space in /var, you can define the following property in your WN profiles :
     243{{{
     244"/software/components/pbsclient/tmpdir" = /home/pbs/tmpdir";
     245}}}
