STDOUT/STDERR

The STDOUT and STDERR fields cause a user process to redirect stdout and stderr of the batch processes to the directory or file specified. The default is to create a file in the users home area with the following form:
FBS_sectionid.logical_pid.[(out|err)]
logical_pid is a unique integer from 1 to NUMPROC assigned by FBSNG to each process in the section. sectionid is the unique section identifier.

If STDOUT/STDERR is specified, FBSNG interprets the string according to the following rules:

• If the string does not start with a '/', the users home area is prepended to the string.
• If the string ends with a '/', the string is interpreted as a directory where the files sectionid.logical_pid.[(out|err)] will be created.
• If the string does not end with a '/', the string is interpreted as the filename that will be created.
• If the string contains `%j', it will be expanded with sectionid
• If the string contains '%n', it will be expanded with the logical_pid of the process.
• If the string contains '%J', it will be expanded with jobid.
• If the string contains '%S', it will be expanded with sectionname.

When a batch process starts on a farm node, it will have the environment variables FBS_PROC_STDOUT and FBS_PROC_STDERR will have the names of stdout and stderr files to respectively.
