2.8 Scratch Space

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
