                Changes to Job Submission Commands
                         January 18, 2007

NCSA made changes in the job submission commands (qsub, bsub and llsubmit)
on all its HEC systems.  This may require you to change the way you
submit batch jobs.

- The new commands require a valid account. (Now, the commands
  automatically pick a valid account for you if the one you
  specify is invalid.)

- The new commands will no longer allow you to use a account that
  is expired or overused, even if that account is still active.

- The new commands will no longer allow you to use a Courtesy
  TeraGrid Roaming account for batch jobs.

- If you have more than one account that can be used for a
  batch job, you will need to either specify the account or
  set a default.

Starting today, you will be automatically prompted for a default
account during the login process if you have more than one account
available for batch jobs. If you run jobs primarily using Globus,
please log into the systems to ensure that you have a default account.

There are a couple of new commands available.  The "batch_accts"
command lists all your accounts on the current system and shows
which are available for batch jobs.  The "defacct" command allows
you to set a default account at any time. For more information
about these commands, please see the man pages.

This is how to specify an account for a batch job on NCSA systems
(where "acct" is the name of the account in the form xxx or TG-XXXXXXXXX):

System       command-line     batch script
------       ------------     ------------
Tungsten     bsub -P acct     #BSUB -P acct
Cobalt       qsub -A acct     #PBS -A acct
Mercury      qsub -A acct     #PBS -A acct
Copper         [none]         #@ account_no = acct
