Guest Vignette

GW, with strong support from government and industry, has played a critical role in advancing the high-performance computing field. In 1995, Professor Tarek El-Ghazawi and his students participated in the Beowulf project at NASA Goddard Space Flight Center; they also played a pioneering role in establishing the area of high-performance reconfigurable computing; and they conceived and specified the Unified Parallel C programming language (UPC), for which El-Ghazawi was a major author. 

More recently, the group has completed and published several works on how using the locality awareness properties of parallel languages like UPC, a computer system can automatically detect appropriate times when data is not yet available at processors and scale down the clock frequency of those processors to reduce power.  In addition, the group is currently researching hardware addressing solutions to reduce the performance overhead associated with managing shared memory operations in parallel computer languages with partitioned global address spaces (PGAS).  The investigated hardware solutions will also manage the co-location of processing and data in future generation supercomputers, which will be characterized with extremely deep hierarchies of memory and processing.  

In order to do this work, GW's High-Performance Computing Lab (HPCL) maintains a state-of-the-art data center at the Virginia Campus.  The lab's cutting-edge hardware includes a Cray XK7 supercomputer named “George” that has approximately 2000 CPU cores (in addition to 32 Kepler Graphical Processing Units or GPUs) and is capable of performing 52 trillion calculations per second (52 TeraFLOPS).  The center also includes a number of other clusters and parallel computers, many of which are accelerated by GPUs or reconfigurable hardware chips (Field Programmable Gate Arrays or FPGAs), or by Sony Play Stations.  Some of those are from leading vendors and some have been built by our own students, who continue to maintain the facility and gain additional practical insights into the field.  In addition to the many post-docs and graduate research assistants, opportunities are often available for undergraduate students to conduct research at the HPCL.  (Provided courtesy of Prof. Tarek El-Ghazawi of the Department of Electrical and Computer Engineering)
