Dear Discovery Users:

I wish to reiterate the following usage guidelines:

1) Please add the following to all "bsub" interactive command line directives and batch job bash shell submit scripts:

"-R span[ptile=<>]"

where <> is the number below based on the queue you are using:

interactive-10g      <>= 16 
ht-10g                   <>= 32
interactive-ib         <>= 16
parallel-ib              <>= 16
ser-par-10g           <>= 16 
ser-par-10g-2        <>= 40
ser-par-10g-3        <>= 40
par-gpu                 <>= 32
hadoop-10g           <>= 40
largemem-10g       <>= 32

For obtaining interactive nodes the bsub directive would read for any queue that is interactive:

>>bsub -Is -XF -n <> -q <queue_name> -R span[ptile=<>] /bin/bash

And when you are done please logout from the interactive node and kill the interactive job using "bkill <job_id>". NOTE above -n and ptile have the same <>.

For batch job the summit script must have one more #BSUB directive without exception:

#BSUB -R "span[ptile= <>]"

Make sure that you do this all the time for any queue you use as you will ensure that you lock the nodes in and no one else can use those nodes and resources in there like GPU's. LSF will close the nodes allocated to you from other users.

2) Please do not run jobs on the login nodes "discovery2" or "discovery4". Get an interactive node for this as shown above.

3) Please monitor your /scratch/<myneu_id> folder usage. If you are using more than 200-300GB over a period longer than 2-3 weeks remove the data using "rsync" to your local folder or email us on how long you expect to use the space over what is recommended. /scratch is not for your long term storage needs.

Thank you again for your patience and consideration in this matter. 

If you have any further questions, require more clarification on usage policy, or need any more assistance in any matter, email us at [log in to unmask] or stop by our office - we are in 2 Ell Hall behind the NEU bookstore.

Best
Nilay
