ARC's collaborations with Computer Science faculty are highlighted in a recent, Microsoft commercial that is airing nation-wide: The VT article with links to the YouTube videos is here, showing Dr. Feng and hist students exploring MPIBlast results with the immersive, embodied and high-resolution displays of the Visionarium Lab.
In Fall of 2014, the Interdisciplinary Center for Applied Mathematics (ICAM) and ARC will offer a three-session short course on Parallel Computing with MATLAB as a part of the Virginia Tech Network Learning Initiatives (NLI) curriculum. The course will be taught by Dr. Eugene Cliff of ICAM in conjunction with Advanced Research Computing. Users can enroll through NLI here.

This spring, ARC will offer fifteen short courses through Virginia Tech Networked Learning Initiatives (NLI), formerly Faculty Development Institute (FDI). These courses will generally be held on Tuesday and Thursday afternoon from 2:00-3:15 in Torgersen 3060. Users can enroll through NLI here.

This fall, ARC will offer nine short courses through Virginia Tech Networked Learning Initiatives (NLI), formerly Faculty Development Institute (FDI). These courses will generally be held each Wednesday afternoon from 3:00-4:45 in Torgersen 3060. Users can enroll through NLI here. Click here for course descriptions and registration information.
Time and location: August 14-15, 2013, 9am-4pm, Torgersen 2150
NVIDIA will hold a two-day GPU-programming workshop, providing a crash course in heterogeneous computing ideal for both new and existing users of HokieSpeed. Lunch will be provided. Interested parties can register here. For more information, click here.
In March 2013, Virginia Tech's Advanced Research Computing (ARC) released BlueRidge, providing faculty, staff, and students with the largest computing asset to date as measured by memory and number of cores. This Cray CS-300 cluster ranked number 402 on the November 2012 Top500 list, the industry-standard ranking of the world's 500 fastest supercomputers, with a score of 86.3 teraflops, or 86.3 trillion floating point operations per second. This is more than eight times the computing power provided by System X, which put Virginia Tech on the supercomputing map in 2003.
BlueRidge, which was purchased through funding provided by Virginia Tech and the State of Virginia, is composed of 318 nodes (individual computers) each outfitted with two octa-core Intel Sandy Bridge central processing units (CPUs) and 64 gigabytes (GB) of memory. In addition, five nodes are equipped with 128 GB of memory for jobs that are especially memory intensive. The systemwide totals of 5,088 cores and 20.4 terabytes (TB) of memory are two and a half times as many cores and four times the memory of any other system at Virginia Tech. BlueRidge is also the first Sandy Bridge cluster at Virginia Tech, an important distinction as Sandy Bridge CPUs have the ability to do twice the number of double precision computations in a single cycle as their Intel Westmere predecessors.
The large number of cores available on BlueRidge will allow Virginia Tech researchers to run massively-parallel simulations, allowing them to tackle more complicated problems more quickly than they have before. And the system's huge memory footprint will enable faculty to investigate the kinds of big data subjects that are increasingly the focus of attention in computationally-intensive arenas.
In addition, ARC is currently working on the addition of two Intel Xeon Phi coprocessors on 130 of the 318 nodes (260 Xeon Phi cards in all), with expected release of those nodes in Fall 2013. This architecture (also known as Many-Integrated-Core or MIC) is considered a significant development in high-performance computing, providing accelerated capability reminiscent of GPUs, but more integration with CPUs and compatibility with existing CPU programming paradigms (C/C++, Fortran, etc).
BlueRidge, the NSF-funded HokieSpeed CPU-GPU cluster, and the shared-memory system HokieOne provide researchers with a variety of options to address specific computing requirements arising from an array of research areas. All of these systems are housed in the university's cooled, access-restricted machine room in the Corporate Research Center and maintained by ARC, a unit within the Office of the Vice President of Information Technology devoted to maintaining, advancing, and providing support to large-scale research computing systems in the university.
