2.8 Scratch Space (parallel version)

You may skip this section if you have installed the serial version of the ADF package.

All processes (the main process started by you and the child processes) will write to disk, often a significant amount of data. You will have to make sure that the scratch space used by all these tasks is both big and fast enough. Use the environment variables SCM_TMPDIR and SCM_USETMPDIR to tell the ADF programs where to create their scratch directories.

In the next few sections we will explain exactly what these variables do.

→ Set the SCM_TMPDIR and SCM_USETMPDIR environment variables.

Example:

SCM_TMPDIR=/local/scratch/$USER
export SCM_TMPDIR
SCM_USETMPDIR=yes
export SCM_USETMPDIR
