Today the Department of Energy’s Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program announced it is accepting proposals for high-impact, computationally intensive research campaigns in a broad array of science, engineering, and computer science domains. DOE’s Office of Science plans to award over 6 billion supercomputer processor-hours at Argonne National Laboratory and […]
In this WUOT podcast, Jack Wells from ORNL describes how the Titan supercomputer helps advance science. “The world’s third-most powerful supercomputer is located in Oak Ridge, and though it bears the imposing name TITAN, its goals and capabilities are more quotidian than dystopian. After that, WUOT’s Megan Jamerson tells us about a project at ORNL that uses TITAN to help humans digest vast sums of information from medical reports. If successful, the project could create new understandings about the demographics of cancer.”
By using multiple grids and separating the modes in the problem onto the various grids most efficiently, the researchers can get through their long line of calculations quicker and easier. “GPUs provide a lot of memory bandwidth,” Clark said. “Solving LQCD problems computationally is almost always memory-bound, so if you can describe your problem in such a way that GPUs can get maximum use of their memory bandwidth, QCD calculations will go a lot quicker.” In other words memory bandwidth is like a roadway in that having more lanes helps keep vehicles moving and lessens the potential for traffic backups.”
A huge barrier in converting cellulose polymers to biofuel lies in removing other biomass polymers that subvert this chemical process. To overcome this hurdle, large-scale computational simulations are picking apart lignin, one of those inhibiting polymers, and its interactions with cellulose and other plant components. The results point toward ways to optimize biofuel production and […]
Oak Ridge National Lab is hosting a 3-day GPU Mini-hackathon led by experts from the OLCF and Nvidia. The event takes place Nov. 1-3 in Knoxville, Tennessee. “General-purpose Graphics Processing Units (GPGPUs) potentially offer exceptionally high memory bandwidth and performance for a wide range of applications. The challenge in utilizing such accelerators has been the difficulty in programming them. This event will introduce you to GPU programming techniques.”
The Piz Daint supercomputer at the Swiss National Supercomputing Centre (CSCS) is again assisting researchers in competition for the prestigious Gordon Bell prize. “Researchers led by Peter Vincent from Imperial College London have made this year’s list of finalists for the Gordon Bell prize, with the backing of Piz Daint at the Swiss National Supercomputing Centre. The prize is awarded annually in November at SC, the world’s largest conference on supercomputing. It honors the success of scientists who are able to achieve very high efficiencies for their research codes running on the fastest supercomputer architectures currently available.”
The Department of Energy’s Oak Ridge National Laboratory will add its computational know-how to the battle against cancer through several new projects recently announced at the White House Cancer Moonshot Summit. “ORNL brings to the table our world-class resources in high-performance computing, including the Titan supercomputer, as well as leading experts in the data sciences and neutron analysis, to the fight against cancer,” said ORNL’s Joe Lake, deputy for operations at the HDSI.”
In this podcast, Shahin Khan from OrionX joins the Radio Free HPC team for a look at the new TOP500 list of the world’s fastest supercomputers. “The 93 Petaflop Sunway TaihuLight supercomputer is not a one-time effort from China. Not only do they now have the two top two supercomputers, China also sponsors the world’s largest state-sponsored Student Cluster Competition with over 170 university teams. The takeaway from today; China is serious about supercomputing, they are in it for the long haul, and they are willing to write the checks to make it happen.”
University of Texas at Arlington physicists are preparing the Titan supercomputer at Oak Ridge Leadership Computing Facility in Tennessee to support the analysis of data generated from the quadrillions of proton collisions expected during this season’s Large Hadron Collider particle physics experiments.
Any performance improvements that could be wrung out of supercomputers by adding more power have long been exhausted. New supercomputers demand new options that will give scientists a sleek, efficient partner in making new discoveries such as the new supercomputer called Summit that’s being developed and is to arrive at Oak Ridge National Lab in the next couple of years. “If necessity is the mother of invention, we’ll have some inventions happening soon,” says deputy division director of Argonne Leadership Computing Facility Susan Coghlan.
