===== GENERAL INFORMATION (as of 14:30 Wed Jul 29, 2015)
============================================================================
Breaking News:
--------------
The NCCS Discover System Administrators have upgraded the operating system
on more than 200 of the 16-core IBM "Sandy Bridge" nodes to SLES 11/SP3.
Please consult the NCCS Web-site for additional details for accessing these
nodes or for alternative job submission options to avoid these nodes at the
following URL:

     http://www.nccs.nasa.gov/images/SandSP1-Web-0727.pdf

Starting Monday, July 27, 2015, in the absence of any submission constraints
your job may be directed to these nodes.  N.B. SGI MPT is unsupported on
the upgraded IBM nodes.  With the reduction in available Sandy Bridge SP1
nodes, the NCCS will attempt to conserve SP1 nodes for jobs that explicitly
request--constraint=sp1.  This change to the node allocation order may
result in jobs that don┬┐t specify any constraints being directed to
Haswell nodes.
----------------------------------------------------------------------------
Discover Users: When creating a ticket to report a Discover job crashing, if
possible please include the job ID.  This will greatly enhance our ability
to diagnose the problem.  Thank you.
----------------------------------------------------------------------------
The MATLAB licenses on discover are in high demand.  If you are not
currently actively using MATLAB on the dali nodes, please exit your session
so that other users may use the local licenses.
