GNU Scientific Library upgraded to version 1.11

The GNU Scientific Library has been upgraded to version 1.11 and is now the default version of GSL on the Hoffman2 Cluster. Point your browser at: GNU Sciencetific Library for information on how to run GSL on the Hoffman2 Cluster.

The old version 1.9 will remain available for a brief period.

OpenMPI 1.2.5 becomes the default MPI library

OpenMPI version 1.2.5 is now the default MPI library on the Hoffman2 Cluster, installed at: /u/local/mpi/openmpi/current

Like before, the default MPI compilers (mpiCC, mpic++, mpicc, mpicxx, mpif77, mpif90) are based on the corresponding Intel compilers (icc, icpc, ifort). The mpi.q script will use OpenMPI. The mvapich2.q script will access the former default.

Hoffman2 Cluster Outage - Monday Apr 14, 2008

Hoffman2 Cluster will be down for several hours on Monday April 14th. You will be unable to login or access the cluster during this period. This outage is to upgrade the firmware on the BlueArc file server.

All jobs running under the Sun Grid Engine, for example jobs you submitted through UCLA Grid, or with a command-line queue script, will be terminated at that time. You will need to resubmit your jobs when the cluster comes back.

Announcing the Research Computing Forum

ATS Research Computing Technologies and IDRE would like to introduce you to a new support tool for your research. The Research Computing Forum, http://forum.idre.ucla.edu/ is available for you to join us and others in the UCLA High Performance Computing community to ask questions, get answers and share your knowledge and successes in your HPC endeavors.

In addition to becoming a virtual gathering spot for the UCLA HPC community, the forum is a place to collect experience and solutions to common problems faced by our community as a whole as well as even more domain specific issues. The ATS staff you have been interacting with through atshpc@ucla.edu encourages you to check the forum for up to date system announcements and answers to commonly asked questions and issues with ATS managed systems. Of course, if you need to contact us for an issue you feel is not appropriate for the forum, please do use atshpc@ucla.edu and we will do our best to help you.
