The output command line directive must be accompanied by a comma-delimited list of case-insensitive options that control how output is generated. The full directive need not be provided — only enough characters are required to uniquely identify the directive. For example, MERGE is sufficient to represent the MERGE-STDERR-TO-STDOUT directive — while TAG can not be used to represent TAG-DETAILED (though TAG-D would suffice).

Supported values include:

  • TAG marks each output line with the [job,rank]<stream>: of the process that generated it

  • TAG-DETAILED marks each output line with a detailed annotation containing [namespace,rank][hostname:pid]<stream>: of the process that generated it

  • TAG-FULLNAME marks each output line with the [namespace,rank]<stream>: of the process that generated it

  • TAG-FULLNAME marks each output line with the [namespace,rank]<stream>: of the process that generated it

  • TIMESTAMP prefixes each output line with a [datetime]<stream>: stamp. Note that the timestamp will be the time when the line is output by the DVM and not the time when the source output it

  • XML provides all output in a pseudo-XML format MERGE-STDERR-TO-STDOUT merges stderr into stdout

  • DIR=DIRNAME redirects output from application processes into DIRNAME/job/rank/std[out,err,diag]. The provided name will be converted to an absolute path

  • FILE=FILENAME redirects output from application processes into filename.rank. The provided name will be converted to an absolute path

Supported qualifiers include NOCOPY (do not copy the output to the stdout/err streams), and RAW (do not buffer the output into complete lines, but instead output it as it is received).
