Update on Cluster Extension

December 13, 2013

The new cluster equipment has begun to arrive from Dell. HPCF personnel will be working with DoIT to update the documentation on this web page while the equipment is set up and tested. During this time, much of the web site will be “under construction” (especially underResources for Tara Users), so please bear with us during the transition.

Cluster Extension Ordered

October 30, 2013

HPCF has selected Dell as the vendor for its next-generation computing equipment, which will used to be extend the cluster tara. The new equipment includes 19 CPU/GPU compute nodes, 19 CPU/Phi nodes, and 34 CPU-only nodes, as well as high performance networking equipment. Each compute node carries two Intel Ivy Bridge processors with eight cores apiece, for a total of 16 cores per node. The GPU and Phi coprocessors present exciting new opportunities for high performance computing. Each CPU/GPU node carries two NVIDIA K20 GPUs, while each CPU/Phi node carries two Intel Phi 5110P accelerators. The web page will be updated in the coming months as the equipment makes its way to UMBC and becomes operational.

pbdR Tutorial

June 16, 2013

HPCF RA Andrew Raim presented a workshop to the department of Math and Statistics on an R package called pbdR for high performance computing. The handout and examples codes are available as Technical Report HPCF-2013-2.

Abstract for Workshop
pbdR (“Programming with Big Data in R”, is a recent package for high performance computing in R offered by the Remote Data Analysis and Visualization Center (RDAV) at the National Institute for Computational Sciences (NICS). pbdR, like its predecessor Rmpi, presents the appealing possibility of high level Message Passing Interface (MPI) programming in the open source math/statistics environment R. pdbR also supports higher level functionality for distributed dense matrix operations and scalable linear algebra. We have recently installed pbdR to the cluster tara at the High Performance Computing Facility ( In this informal tutorial, we will demonstrate running pbdR programs through the scheduler on tara and some of the basic capabilities of the software.

HPCF Cluster tara #15 on Green Graph 500 List

April 02, 2013

The cluster tara has placed #15 on the (unofficial) Green Graph 500 List. This list ranks systems on the Graph 500 list by the efficiency of their energy consumption. In Summer 2012, a team of undergraduate students in the REU Site placed tara on the Graph 500 list, from which the ranking in the Green Graph 500 list is derived.

tara Places 98th in November 2012 Graph 500 List

November 13, 2012
A team of undergraduate students participating in the Summer 2012 HPC REU Site took on theresearch project to implement and run the Graph 500 benchmark to assess the performance of the cluster tara. This benchmark measures performance in accessing memory, as opposed to CPU performance which is emphasized in more traditional benchmarks for HPC. The submission was accepted, and tara ranked 98th on the November 2012 list. For details, see the technical report HPCF-2012-11 in our publications.The ranking was announced at the Supercomputing 2012 conference in Salt Lake City. Pictured are (left to right) the client David Mountain, mentor Dr. Matthias Gobbert, and students Jordan Angel, Nathan Wardrip, and Amy Flores, holding the official certificate for the ranking. Not able to join them at the conference were client Richard Murphy and student Justine Heritage. We acknowledge funding support for the student travel from the National Security Agency and the National Science Foundation. graph500-sc12-thumb

User meeting on scheduling policy

June 15, 2011

The user meeting on the new scheduling policy on June 15 was attended by 16 members of the user community. First, Dr. Gobbert explained the philosophical ideas behind the new design: Any user can submit as many jobs as desired; when another users submits a job, it should have a higher priority than the already queued jobs, assuming equal priority in other respects. This and other principals are contained in SLURM’s fair-use feature that we are using now. Then, HPCF RA Andrew Raim detailed the synta of the SLURM submission script to access the features of its fair-use feature.

Changes to scheduling and usage policy

June 14, 2011

Major updates to the scheduling policy on tara were implemented on Tuesday, June 14. These include adoption of fair-share priority, QOS’s, and a change to the available partitions. All users should check the following pages:
