CHECS building world's largest power-aware research cluster. We have recently taken delivery of the components necessary to assemble a new cluster dedicated to high-end computing systems research, with a particular emphasis on power-aware systems. The system consists of 324 Mac Pro towers, with each node containing dual quad core 2.8GHz Xeon processors for a total of 2,592 cores. The system interconnect is a quad data rate (QDR) InfiniBand network, making this the first large-scale cluster to employ QDR. In addition to work in power-aware systems, the cluster will support a wide range of basic and applied high-end computing research, including projects in transparent distributed shared memory systems and high-performance distributed storage systems, and collaborations with computational scientists and engineers. The cluster is funded in part by significant support from NSF and from Virginia Tech's College of Engineering.

CHECS Director Srinidhi Varadarajan reports that this is an exciting time for Evergrid, the company he co-founded and for which he serves as chief technology officer. Evergrid recently announced the Cluster Availability Management Suite (CAMS), a resource management system for high-productivity computing grid environments and the utility enterprise datacenter. CAMS is integrated with Evergrid's Availability Management Service (AvS) to provide checkpoint/resume capabilities for applications, including massively parallel distributed applications.
SCAPE Laboratory researchers have created a first-of-its-kind tool for profiling the temperature of source codes. Tempest is a "Temperature Estimator" that runs on any system with LMSensors installed and has been successfully tested on a number of x86, x86_64, PowerPC, multi-core, and multi-processor systems. Tempest provides a thermal profile of an application and correlates temperature data to source code. Tempest development was led by Hari K. Pyla and Prof. Kirk W. Cameron of SCAPE. For more information, see this news item on Tempest at the CS Department homepage.
Ph.D. student Filip Blagojevic and Dimitris Nikolopoulos, director of the Parallel Emerging Architectures Research Lab (PEARL), won the best paper award at the 12th ACM Symposium on Principles and Practice of Parallel Programming (PPoPP), held in San Jose, CA March 14-17. The paper, titled “Dynamic Multigrain Parallelization on the Cell Broadband Engine," was selected among 22 papers accepted in the conference. The paper was co-authored with Alexandros Stamatakis (Swiss Federal Institute of Technology) and Christos Antonopoulos (College of William and Mary).
CHECS students and faculty have had several opportunities in recent weeks to interact with researchers visiting from other universities. David Lowenthal (University of Georgia) visited CHECS on February 23 and presented his work in "High-Performance, Power-Aware Computing." On February 27 Xiaosong Ma (NC State) made the trip up to Blacksburg and gave a seminar on "Transparent and Efficient Parallel Processing for End Users of Scientific Data." Anand Sivasubramaniam (Penn State) visited on March 15, presenting a seminar on "Power Management for Server Disks." Finally, Alexandros Stamatakis (Ecole Polytechnique Federale de Lausanne) described his research on "Algorithmic and HPC Challenges for Large-Scale Phylogeny Reconstruction" in a March 30 seminar.
The SCAPE Lab has begun collaborating with IBM research to port the PBPI framework to BlueGene/L, the world's fastest supercomputer. PBPI is a freely available portable implementation of parallel Bayesian phylogenetic inference. PBPI estimates phylogenetic trees using MCMC-based Bayesian inference on distributed-memory computers. The code was developed by SCAPE director Kirk Cameron, postdoc Xizhou Feng, and collaborator Duncan Buell (University of South Carolina).
The 21st IEEE International Parallel and Distributed Processing Symposium (IPDPS) was extremely selective this year in its selection of research papers. A total of 109 papers were selected from among 419 submissions (26%) making the competition particularly keen. CHECS will be very well-represented at the conference (held March 26-30 in Long Beach, CA), accounting for four of the 109 papers to be published in the conference proceedings. The research reported in these papers is directed by three CHECS faculty members, Kirk Cameron, Dimitris Nikolopoulos and Srinidhi Varadarajan. Co-authors include PhD students Filip Blagojevic, Rong Ge and Joseph Ruscio. For more information on the four papers, see the CS Department's news item on IPDPS.
CHECS researchers are studying programming approaches and performance optimization for the Sony PlayStation3. The Cell Broadband Engine, the processor at the heart of the PS3, is a heterogeneous multicore architecture which offers interesting opportunities for exploiting dynamic multi-grain parallelism. Students from Dr. Dimitris Nikolopoulos's Parallel Emerging Architectures Research Lab (PEARL) have been working with a Cell simulator for about one year. In December they, along with members of Dr. Kirk Cameron's Scalable Performance Laboratory (SCAPE), got their hands on a new PS3 and begin porting and running two leading computational phylogenetics packages, RAxML and PBPI. RAxML infers phylogenetic trees using a rapid hill climbing search algorithm and the Maximum Likelihood method. The code was developed by researchers at EPFL in Switzerland and optimized for the Cell BE by Nikolopoulos and PhD student Filip Blagojevic. PBPI, developed by Cameron and postdoctoral student Dr. Xizhou Feng, infers phylogenetic trees using a Markov chain Monte Carlo based method. Both of these projects leverage novel models and runtime environments developed by the research groups of Nikolopoulos and Cameron, for exploiting multi-grain parallelism on accelerator-based parallel architectures.
The first CHECS 'mixer' of the semester was held on February 1. Over 40 students and faculty attended, attracted in part by a desire to discuss CHECS initiatives over the next few months, and in part by the promise of pizza. Cal Ribbens (CHECS Associate Director) gave an overview of the goals and status of the center as well as mentioning a large sample of current projects. Ribbens' ppt slides are available here.
CHECS was well-represented at the SC06 conference in Tampa in November. Over 25 faculty and students from Virginia Tech were in attendance, including six faculty and nine students from CHECS. In addition to presenting three papers and a poster, CHECS members helped staff the Virginia Tech booth on the showroom floor. Three CHECS graduate students served as student volunteers at the conference as well. And CHECS director Srinidhi Varadarajan stayed busy on the showroom floor, representing both VT and a startup he is involved with. Varadarajan is CTO and co-founder of Evergrid, a provider of high availability and resource management software that lets massively parallelized distributed applications run at near 100 percent reliability on high performance computing clusters. Varadarajan and his colleagues demonstrated several software technologies, including a new virtualization layer.
Wu Feng served as program co-chair for the 15th IEEE International Conference on Computer Communications and Networks (ICCN06), held October 9-11 in Arlington, VA.
