Subject: SCF Batch News - Longer run time limits on the Katana Cluster

Dear Researchers,

In response to feedback from the BU Research Computing community, we have
increased the maximum run time limit on the Katana Cluster. An individual can
now have up to 4 processors running for a maximum of 72 hours. These
processors count toward an individual's maximum limit of 64 simultaneously
running processors.

These longer running jobs will all be running on two new nodes just added to
the Katana Cluster, katana-h01 and katana-h02. Each of these two nodes has 12
processors for a total of 24 processors. Any of the 24 may be used for the
extended run time, but only a maximum of 12 are currently permitted to run
simultaneously for the extended time. For all other processors, the 24 hour run
time limit continues to apply. The default run time limit continues to be 2
hours and longer times must be specified. Please see the Running Jobs page
(http://www.bu.edu/tech/research/computation/linux-cluster/katana-cluster/runningjobs/)
for details.

Please note that many large jobs can be split into a few smaller jobs and/or
checkpointed so they can be managed well in a shared computer environment. If
you need help with that, please don't hesitate contacting one of our
Programming Consultants, Doug Sondak (sondak@bu.edu) or Kadin Tseng
(kadin@bu.edu), for assistance. More detailed information on the systems is
available on the web in the Technical Summary at:
http://www.bu.edu/tech/research/computation/about-computation/tech-summary/ 

If for some reason your code is not able to run using the standard 
configuration, please don't hesitate to send e-mail to help@scv.bu.edu to let
us know of any problems or difficulties you have in using the systems. We will
do everything in our power to help you with your issue.

Sincerely,
