TACC Lonestar


Cluster details

This cluster runs LSF as the default job manager/scheduler. You can run urgent jobs on these resources using either the 'spruce_sub' or the Globus extensions.

Policy

TACC Lonestar policy map is as follows -

red - 'next-to-run'
orange - 'next-to-run'
yellow - 'next-to-run'

Initial Setup

  • 1) Login to the machine- ssh -A username@tg-login.tacc.teragrid.org
  • 2) Check if the variable $TG_COMMUNITY is set. This will be the base of the SPRUCE community space you would need to access. If not set, please set it to /projects/tg or contact us for further instructions.
  • 3) Compile your codes and have them handy in your home directory tree.

spruce_sub

Invoke the spruce_sub command with the urgency and job script specified. The script can be found here -

$TG_COMMUNITY/spruce/bin

More about running jobs using spruce_sub can be found here.

Globus submissions

SPRUCE jobs can be submitted as any other Globus job. An additional urgency parameter and the right contact string are all that needed.

NOTE: On Lonestar SPRUCE is a part of the default job manager rather than a new component, so you will need to contact the lsf job manager itself.

The urgency level can take three values -
(urgency=yellow/orange/red)
and
the contact string is -
tg-login.tacc.teragrid.org/jobmanager-lsf

More about running jobs using Globus interface can be found here.
