26 May, 08:30 is planned time for Hexagon software upgrade. It will be upgraded from UNICOS/lc 2.0 to CLE 2.1UP02. It is an major software upgrade and will take from several hours to several days. We will use our bests to minimize the downtime.
Lustre FS is going to be upgraded from version 1.4 to 1.6 which will need /work filesystem check for several hours. We kindly ask hexagon users to remove all unused files from /work filesystem, this will result in shortening downtime.
ALL programs which are going to be used after software upgrade MUST be recompiled! This is very important! Running application compiled for current OS release (2.0) can create unexpected results after upgrade.

Update: Upgrade time moved to 26.05.2009 08:30. Therefore hexagon reserved from 08:30, 26th of May. Long jobs which are not able to complete before the downtime will not start.

Update: May 27th 00:00: The upgrade will continue tomorrow. The machine will be unavailable until the upgrade is finished.

Update: May 27th 16:00: We have started recompiling software on Hexagon.

Update: May 27th 21:30 Software upgrade finished. Hexagon is back online.

As it was mentioned before this is MAJOR software upgrade. Now hexagon is running CLE 2.1UP02, with Lustre 1.6 filesystem

hdf5
hdf5-parallel
all netcdf:
netCDF (for version 3.6.2)

* The libraries like:
zlib

are available by default without modules

* Module name: changed program name and version number structure, like:
%ProgramName/%Version
eg. nwchem-cnl/5.1.1
netCDF/3.6.2
While loading modules, users are advised to use as much as possible only the program name, the optimal version will be loaded by default:
module load nwchem

* Please update your PBS scripts as well as environment to load correct modules.
