Download slides [1.6 MB]: NVIDIA-GTC-MWA A popular account of the SciGPU project has been posted online by the Harvard News Office. Writer Alvin Powell describes the “trio of projects at Harvard whose massive computing needs have prompted investigators to join forces to pioneer new computing techniques that will benefit not just radio astronomy, but quantum chemistry and neuroscience as well.” In interviews [click on link for more...] The SciGPU collaborators welcomed four students who came to Harvard for NSF-funded Research Experiences for Undergraduates during summer 2009: Dominik Gothe (University of South Carolina; astronomy), Matthias Lee (Wentworth Institute; time series analysis), Beatrice Perez (University of Puerto Rico; quantum chemistry), and Bo Wang (University of Pittsburgh; neuroscience). The SciGPU REU students were among [click on link for more...] Our four summer Research Experience for Undergraduates (REU) students (Dominik Gothe, Matthias Lee, Beatrice Perez and Bo Wang) recently gave excellent presentations on the research they conducted this summer. Their work covered the Murchison Widefield Array, Quantum Chemistry, the Connectome and the Time Series Centre. Copies of their talks are now available for download. Gothe_MWA_Areas High Performance Computing as Linchpin in Next-generation Radio Telescopes Abstract The Murchison Widefield Array (MWA) is a radio telescope currently under construction in Australia. It is an interferometer, consisting of over 500 antenna tiles spread over an area of about a square kilometer. The signals from these tiles are synthesized into images by the Real Time System (RTS). In this talk, Richard Edgar describes why [click on link for more...] The following news was released April 2, 2009 by NVIDIA Corporation. The company’s release can be found here. SANTA CLARA, CA—NVIDIA Corporation, inventor of the GPU, today announced that Harvard University has been recognized as a CUDA Center of Excellence for its commitment to teaching GPU Computing and its integration of CUDA™-enabled GPUs for a host [click on link for more...] |
