The XLF12 compiler has become the default on bluefire. A bug has been identified when users use the -qarch=pwr6 option, and this is being worked on with IBM.
The normal recommended -qarch option is -qarch=auto. Users are strongly cautioned that they should change any compilation scripts that use pwr6 (or older pwr5 and pwr4) to auto. Failure to do this may cause node failures requiring significant repairs.
Lightning users are being notified that the system will be decommissioned on Tuesday, December 1.
Home directories will be backed up to the Mass Storage System shortly before the system is turned off.
Users are advised to begin moving their work onto one of the other CISL production platforms, including bluefire or the data analysis and visualization cluster. The latter system is a Linux cluster. For further information on the DASG cluster, see: http://www.cisl.ucar.edu/hss/dasg.

An announcement was made last month about the decommissioning of the NCAR MSS and the transition to a new HPSS archival system. For the announcement text see:
http://www.cisl.ucar.edu/news/09/0909.hpss.jsp
As an initial step in this transition effort, the msread/mswrite interface to the legacy NCAR MSS is being phased out by Dec 31, 2009. This is the first of several intermediate steps that will be taken to ensure a more manageable final transition from the NCAR MSS to HPSS. For further specific information on how to transition away from msread/mswrite to DCS for the legacy MSS see

Users are also strongly encouraged to visit the MSS/HPSS transition website at
http://www.mss.ucar.edu/transition
for general information on the MSS->HPSS transition, and for pointers on issues to be considering in developing your own personalized transition strategies.
The xlf 12.1 compiler upgrade took place on October 17, 2009. A PowerPoint presentation showing differences from xlf 11 is available at:
http://www.cisl.ucar.edu/hss/csg/presentations/xlf12-xlf11_diffs.ppt
Note that the Visual Age C/C++ compiler was also upgraded to v. 10.1.
CISL installed Totalview 8.7 under the default path of /usr/local/bin on October 5.Procedures for memory leak debugging are simplified using the new MemoryScape component. Please see instructions in the bluefire user guide:
