Center for Scientific Computing and Visualization Research will acquire a new rapid prototyping machine
April 13, 2017
UMass Dartmouth Center for Scientific Computing and Visualization Research will acquire a new rapid prototyping machine, a powerful computer server intended for use in collaborative multidisciplinary research among faculty members and students from different departments with diverse programming background. The new rapid prototyping server (rps) is a single high-end Linux server with 3.2 GHz multicore Xeon CPUs, 256GB RAM, and can handle up to 4 GPUs. Popular rapid prototyping software such as anaconda python 2 and 3, Julia, MATLAB with parallel computing toolbox, and Mathematica with GPU support will also be installed. With convenient feature such as UMassD logon, the server can also be seen as an extension of faculty's office workstations or as a test machine prior to scaling up computing jobs to UMass Dartmouth multinode servers: ARNiE and HPCC or MGHPCC (UMass-wide supercomputer). The older rapid prototyping server will be repurposed as a machine for teaching introduction to scientific computing (MTH280), mathematical and computational consulting (MTH540), and high performance scientific computing (EAS520) courses. Prototyping projects currently conducted on the older machine includes but not limited to deep learning with Mathematica, numerical simulation of systems of PDEs, development of new time-stepping methods, and preconditioning techniques for generalized finite difference sparse systems. Smooth transition from older to new rps system will be expected in the summer of 2017.
The University of Massachusetts Dartmouth's Center for Scientific Computing & Visualization Research (CSCVR) has contributed 120 GPU servers to the UMass shared computational cluster installed at the MGHPCC (full article here)
The UMass shared cluster at the MGHPCC is a large (~15,000) processor-core supercomputer system that serves the entire UMass system's computational scientists. From astrophysicists at the Amherst and Dartmouth campuses, to biomedical researchers at Worcester, this key central facility provides the computational resources needed to advance world-class research programs across the system. While a large number of processors is the most common way to build powerful supercomputers today; lately advances in graphics processors (GPUs) has allowed them to be used as accelerators for scientific calculations often delivering a speed-up of over an order-of-magnitude.

CSCVR undergraduate Cole Freniere publishes research article in Computing in Science & Engineering
October 9, 2016
CSCVR undergraduate Cole Freniere, along with CSCVR faculty members Ashish Pathak, Mehdi Raessi and Gaurav Khanna, explore Amazon's Cloud Computing resources for the simulation of Ocean Wave Energy Converters interacting with ocean waves. These wave energy converters are complex to simulate, and traditionally require a large supercomputer to run for an extended period of time. Amazon, whom we all know for its large online store, also offers computing resources in the Cloud, which customers can essentially rent". The novel cloud computing model offers the possibility of reducing the cost of computational fluid dynamic simulations and unlocking the potential of wave energy converters as a future source of renewable energy.
CSCVR acknowledges the 98th birthday of Katherine Johnson
August 22, 2016
The Center for Scientific Computing and Visualization Research would like to acknowledge the 98th birthday of Katherine Johnson on August 26.2016. Katherine Johnson was a pioneering African American woman in the field of computational mathematics. Her work at NASA over many decades had major impact in computational space science.
Today, major advances in nearly all types of science and engineering are aided by computation. Indeed, high-performance computing (HPC) or supercomputing is now considered as the third pillar of scientific discovery alongside experiment and theory. Massachusetts universities (both public and private) excel in this emerging area and have a strong and diverse group of computational scientists and engineers across each campus.
UMass Dartmouth’s Center for Scientific Computing & Visualization Research (CSCVR) organized and hosted “HPC Day 2016” on May 17th — a conference to showcase compute intensive research from researchers in this community from all over Massachusetts. There were participants from: Northeastern University, Boston University, MIT, UMass Amherst, Dartmouth & Lowell and even industry. A special poster session with awards for student projects was included as well. This conference was a follow-on event from the inaugural “UMass HPC Day” conference hosted at UMass Dartmouth in 2014.
The event featured a total of 11 talks with topics ranging from engineering microbial systems to renewable energy extraction from the ocean. Over 145 attendees registered in this event in total and 30 student posters were presented. More details on the program may be found on the CSCVR website. Six awards were granted that were made possible via generous donations by Nvidia, SIAM and MathWorks. The conference lunch was sponsored by Microway Inc.
The keynote speaker was Dr. Jeremy Kepner from MIT Lincoln Lab who gave an fascinating and deeply engaging lecture titled “Interactive Supercomputing for High Performance Data Analysis.” The event also featured an interactive Education Panel that included stakeholders from industry and academia to discuss issues associated with HPC education and training.
The CSCVR also used this event to debut a new innovative, prototype supercomputer built entirely of mobile-devices (in particular, Nvidia Tegra X1 components used to build tablets) dubbed “Elroy”. The system’s total compute capacity is 16 Tflop/s and consumes just over 300W total power. The unique feature of this 32-node system is its extremely high power efficiency -- an order-of-magnitude larger than traditional systems. This was made possible by leveraging recent, very significant power-efficiency related advances that have been cleverly engineered into current cell phones and other mobile devices (to prolong battery life). Power-efficiency is a limiting feature in large scale supercomputing as well, due to the expense associated to large power consumption and corresponding cooling requirements. Elroy demonstrates a unique approach towards potentially meeting this challenge. This project was a result of a collaborative effort between the CSCVR and UMass Dartmouth CITS. The CSCVR has a history of developing innovative supercomputers from using gaming consoles to more recently, using video-gaming graphics cards.
The CSCVR provides undergraduate and graduate students with high quality, discovery-based educational experiences that transcend the traditional boundaries of academic fields, and foster collaborative research in the computational sciences. The CSCVR's computational resources are being utilized to solve complex problems in the sciences ranging from the modeling of ocean waves to uncovering the mysteries of black hole physics.

Computational Simulation of the Interior of a Rotating Black Hole
January 21, 2016
Physicists Lior Burko at Georgia Gwinnett College, Gaurav Khanna at the University of Massachusetts Dartmouth, and Anil Zenginoglu at the University of Maryland have published a Rapid Communication in Physical Review D , that includes the first computer simulation of the interior of a rotating black hole. New mathematical and computational techniques had to be developed to perform the simulations accurately. The high-precision computations involved were particularly intensive, requiring the novel GPU-supercomputing resources of the CSCVR. This research was supported by the National Science Foundation. The Center for Scientific Computing & Visualization Research (CSCVR) promotes the mission of UMass Dartmouth by providing undergraduate and graduate students with high quality discovery-based educational experiences that transcend the traditional boundaries of academic field or department, and foster collaborative research in the computational sciences within the university and with researchers at other universities, national labs, and industry. Khanna serves as the associate director of the CSCVR. Read the full Forbes story and UMassD press release

Supercomputers donated to UMass Dartmouth will help triple data capacity
July 4, 2015
New supercomputers donated to UMass Dartmouth are expected to greatly increase the university's data capacity and research capabilities. "The donated supercomputer will triple our computational capability at the Center for Scientific Computing and Visualization Research," said associate professor Gaurav Khanna, who studies how black holes captures stars.
The University of Massachusetts Dartmouth’s Center for Scientific Computing & Visualization Research (CSCVR) has received donations of two supercomputers that were built and used for mining Bitcoins.
Bitcoin is a digital currency that has garnered a lot of popular media attention recently. In addition to buying a Bitcoin, that runs for around $250 these days, one can also "mine" or generate it, using a powerful computer by solving a cryptographic puzzle. However, Bitcoin is designed in a way that the more mining that occurs, the harder it becomes to mine via an exponential increase in its complexity. So, a powerful computer today that could mine effectively, in a few months would be essentially worthless due to the rapid increase in Bitcoin's complexity. Now, there are investors that built very large supercomputers solely designed to mine Bitcoins — some spending even millions of dollars to build these systems — that are now largely useless, at least from the Bitcoin mining perspective. These machines are sitting idle or simply turned off.
In December 2014, the New York Times’ Laura Parker covered Prof. Gaurav Khanna’s novel use of PlayStations for his computational research in black hole astrophysics in a full length article. Two Bitcoin mining investors read the story and decided to donate their large supercomputers to the university campus for enabling research productivity further in the CSCVR.
The two donated systems are very well suited to enable research in the CSCVR. The key feature of both systems is that they are GPU-accelerated i.e. they use high-end video-gaming graphics-cards to speed up numerical calculations significantly. These make the systems excellent for a large variety of scientific applications. The larger system amongst the two was built in 2012 at cost nearing a million dollars and consists of 180 servers installed in 10 racks, integrated tightly over a fast network. Its replacement cost today could be in ballpark of $400,000.
The donor, Daniel Driscoll of San Francisco shares his thoughts on his donation: "This past winter during my morning commute, I stumbled across an article about a research project that recently used a networked super computer modeling the physics of black holes. Having grown up in the 80's next to the shuttle launch pad in Cape Canaveral, Florida, I remain an ardent fan of all things space. What struck me as even more interesting was how Professor Gaurav Khanna had created this super computer from now derelict Playstation 3 consoles. Being now part of the game industry, I was all too familiar with the transition of Playstation fans to the new flagship, the Playstation 4, and had myself done a few experiments to understand the potential uses for the no-doubt countless number of old Playstation 3's likely going to the trash. One such experiment involved a private venture to explore and understand the Bitcoin craze of 2013, a venture that ultimately proved fruitless but left me in possession of not just several Playstations, but all also a large collection of what I had deemed a more effective array of server computers. Now that bitcoin has come and gone for the hobbyist farmer, Professor Khanna and the University of Massachusetts Dartmouth has provided me an opportunity to join those explorers I once grew up with, if only in my own small way."
The donor of the smaller system chose to stay anonymous; the university respects their privacy and therefore will not comment on any further details.
Prof. Sigal Gottlieb, the Director of the CSCVR remarks on how the donation would impact the research productivity of the Center: "The new computational cluster will be a tremendous addition to the resources of the CSCVR. The new system will triple the computational power available to us, significantly increasing our research abilities. All CSCVR members, and our students, will benefit from this valuable computational tool as we continue to expand the scope and range of the computational problems we are attacking."
Moreover, multiple new faculty that are joining the university would also be able to utilize the same resources to jump start their research programs. In the long run, the large computational resources of the CSCVR will help attract top talent (both faculty and students) to the campus and thus strongly enhance the campus’ research profile. College of Engineering and Campus’ IT services have worked hard and supplied resources to accommodate this significant sized supercomputer, and are committed towards ensuring full utilization of the system.
The CSCVR provides undergraduate and graduate students with educational experiences in supercomputing and fosters collaborative research in the computational sciences within the university and with researchers at other universities, national labs, and industry. Khanna serves as associate director of the Center.

The RC5 cryptography challenge (Wikipedia) was originally started by RSA Laboratories as a worldwide contest to decode a cipher by finding the secret cryptographic key using a brute-force approach. The 72-bit version of the same contest continues today, conducted by distributed.net -- one of the oldest open public distributed computing projects on the internet.
Professor Gaurav Khanna of the Physics Department and associate director of the Center for Scientific Computing and Visualization Research (CSCVR), and computer technician Glenn Volkema, have built a novel supercomputer using consumer video-gaming components (over a hundred Sony PlayStations and multiple AMD Radeon graphics-cards) that has enabled the campus' rank to soar to the absolute top of the RC5-72 contest participant list (link).
This unique system is generating approximately 50 billion keys per second and is slated to have a 1 in 10 chance for winning the contest all by itself!
The supercomputer has been built to study various astrophysical problems associated to binary black hole systems and gravitational radiation. Physics Department graduate students, Tyler Spilhaus and William Duff are already utilizing the system extensively for their research projects in this context. In addition, Computer and Information Science major, Violet Pfeiffer will be using the system to study different aspects of cryptography and cybersecurity.
