Hopper OS upgrade and new SW set to default next Wed, Feb 27
February 21, 2013 by Helen He
1) There will be a scheduled hardware and software maintenance for Hopper next Wednesday, February 27, from 7 am to 7 pm Pacific time. This is a major OS upgrade. Most applications are highly recommended to recompile (or at least relink) after the maintenance. C++ and PGAS applications are recommended to recompile and relink. Please plan your work accordingly and check the NERSC Message of the Day (MOTD) for status update: http://www.nersc.gov/live-status/motd/.
2) After the maintenance, the following software versions will be set to default on Hopper:
-- cray-mpich2/5.6.0 (xt-mpich2/5.6.0); cray-shmem/5.6.0 (xt-shmem/5.6.0)
-- cray-libsci/12.0.0 (xt-libsci/12.0.0)
-- cray-petsc/3.3.00 (xt-petsc/3.3.00); cray-petsc-complex/3.3.00 (petsc-complex/3.3.00)
-- cray-hdf5/1.8.9; cray-hdf5-parallel/1.8.9
The availability of the above software versions were announced on Dec 19 and Jan 18.
Notice Cray has changed some of the module names from "xt-xxx" to "cray-xxx", for example: xt-libsci is now cray-libsci, and xt-mpich2 is now cray-mpich2. Also some of the Cray supported modules now have a "cray-" prefix to their module names, for example: netcdf is now cray-netcdf, and petsc is now cray-petsc, etc.
