ecaccess-queue-list - List available queues
SYNOPSIS
ecaccess-queue-list -version|-help|-manual
ecaccess-queue-list [-debug] [queue-name]
DESCRIPTION
Two different types of queues are in use with ECaccess:
1 - The ECaccess batch queues, which correspond to one system at ECMWF with its specific batch environment, e.g. ecgate will be the
ECaccess queue, which will redirect jobs to ecgate at ECMWF, running LoadLeveler. This ECaccess queue will be given as argument when
submitting a batch job.
2 - The batch queues (or classes) on the systems at ECMWF will be given in the batch job with #@ class = for LoadLeveler.
The names of the ECaccess queues and associated batch queues at ECMWF can be seen with this command. When an ECaccess queue-name is
specified then the details for this queue are displayed (including the list of classes).
The first ECaccess batch queue in the list is the default queue when submitting a batch job with the ecaccess-job-submit command.
ARGUMENTS
queue-name (optional)
The name of the ECaccess queue to retrieve the details.
OPTIONS -version

-help Print a brief help message and exits.
-manual Prints the manual page and exits.

EXAMPLES
ecaccess-queue-list
