We are turning the Spear system off from 5-8pm on Friday, May 1 for a planned power outage.

UPDATE Apr 21 - We are still working our Lustre issues. Spear and Lustre are still unavailable. Yesterday (Sunday, April 19), the data center in Dirac suffered a brief power outage. Most systems are back online now, but there are lingering issues with the Lustre filesystem. This means that …

This summer, we are going to replace the scheduling and job management software on the High Performance Computing Cluster with a new package called Slurm. Slurm will replace the current MOAB/Torque workload manager that we have been using for the past eight years. This will affect all HPC users.

A publication by Bin Chen , a member of applications group has been accepted for publication in the journal Astrophysical Journal Supplement Series . The article titled "Algorithms And Programs For Strong Gravitational Lensing In Kerr Space-time Including Polarization" used the HPC, Matlab and …

HPC jobs are traditionally compiled and run in low-level languages, such as C and Fortran. The reason for this—speed. Parallel libraries like OpenMP, MPI or gpGPU accelerators enable code to run in parallel faster on more hardware. Conversely, higher level interpreted languages like Python …

UPDATE (Mar 4): These issues have been resolved; thanks for your patience. We are experiencing some problems with our job scheduler; it is running but will not/very sporadically accept new jobs and will timeout when you try to access job information (for example, with checkjob ). Running …

Starting today, we have enabled the ability to submit and manage Condor jobs from the HPC Login nodes. This will provide several benefits: Condor users can now use the extensive collection of software packages installed on the HPC Login nodes for Condor jobs The Condor scheduler will run …
