Shukla, a 2004 recipient of a Presidential Early Career Award for Scientists and Engineers (PECASE) and a 2008 recipient of the Freidrich Wilhelm Bessel Award from the Humboldt Foundation of Germany, http://www.ece.vt.edu/faculty/shukla.php wrote the paper with his current Ph.D. students, Mahesh Nanjundappa and Bijoy A. Jose, also of Virginia Tech, and a past Ph.D. advisee Hiren D. Patel who is now an ECE assistant professor at the University of Waterloo in Canada.
Shukla and his collaborators said that they were able to demonstrate how to speed up the simulation performance of certain SystemC based hardware models "by exploiting the high degree of parallelism afforded by today's general purpose graphic processor units (GPGPU)." These units have multiple core processors capable of very high computation and data throughput. When parallelism is applied, it means that the processor units can run various parts of the simulations simultaneously, and not just as a single sequence of computations. Their experiments were carried out on an NVIDIA Tesla 870 with 256 processing cores. This equipment was donated to Shukla's lab by NVIDIA during fall 2008.
Shukla said their preliminary experiments showed they were able to speed up SystemC based simulation by factors of 30 to 100 times that of previous performances.
They named their simulation infrastructure SCGPSim. The Air Force Office of Scientific Research and the National Science Foundation helped support this research.
In the past, Shukla said, "significant effort was aimed at improving the performance of SystemC simulations, but little had been directed at making them operate in parallel. And none of the attempts were ever targeted at a massively parallel platform such as a general purpose graphic processor unit."
Another aspect of their work was the use of a specific programming model called Compute Unified Device Architecture (CUDA). It is an extension to the C software language that "exploits the processing power of graphic processor units to solve complex compute-intensive problems efficiently," Shukla explained. "High performance is achieved by launching a number of threads and making each thread execute a part of the application in parallel."
The CUDA execution model differs from the more commonly known central processing unit (CPU) based execution in terms of how the threads are scheduled. With CUDA, it is possible to have all of the threads execute simultaneously on separate processor cores and intermittently converge on the same path, thus increasing the efficiency.
The work at Virginia Tech was conducted in the Formal Engineering Research with Models, Abstractions and Transformations (FERMAT) Laboratory, founded by Shukla in 2002. Its focus is in designing, analyzing and predicting performance of electronic systems, particularly systems embedded in automated systems. http://www.fermat.ece.vt.edu/
"Speeding up simulation of complex hardware models is extremely important for semiconductor electronics industry to producer newer and newer products in shorter times, thus improving the quality of computing and consumer electronics products faster. If such models can be simulated 10 times faster, then if validating a model took 10 days in the past, now it would take one day. This is why faster simulation performance probably attracted the attention of the ASP-DAC '10 awards committee." Shukla said.
ASP-DAC is one of the three conferences sponsored by IEEE Circuits and Systems Society, and ACM Special Interests Group on Design Automation, on the topic of electronics design automation. These three conferences are held every year in the US (DAC) , in Europe, and in the Asia-pacific region (ASP-DAC).
Virginia Tech's College of Engineering is internationally recognized for its excellence in 14 engineering disciplines and computer science. As the nation's third largest producer of engineers with baccalaureate degrees, undergraduates benefit from an innovative curriculum that provides a hands-on, minds-on approach to engineering education. It complements classroom instruction with two unique design-and-build facilities and a strong Cooperative Education Program. With more than 50 research centers and numerous laboratories, the college offers its 2,000 graduate students opportunities in advanced fields of study, including biomedical engineering, state-of-the-art microelectronics, and nanotechnology.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
