Radio Free HPC Looks at Sunway TaihuLight – the World’s Fastest Supercomputer

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.”

Supercomputing LHC Experiments with Titan

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.

Slimming Down Supercomputer Power Bills

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.

INCITE Seeking Proposals to Advance Science with Leadership Computing

The DoE INCITE program is now accepting proposals for high-impact, computationally intensive research campaigns in a broad array of science, engineering and computer science domains.

Princeton Plasma Physics Lab Wins 80 Million Processor Hours on Titan Supercomputer

The U.S Department of Energy has awarded a total of 80 million processor hours on Titan supercomputer to an astrophysical project based at the DOE’s Princeton Plasma Physics Laboratory (PPPL). The grants will enable researchers to study the dynamics of magnetic fields in the high-energy density plasmas that lasers create. Such plasmas can closely approximate those that occur in some astrophysical objects.

Allinea Scalable Profiler Speeds Application Readiness for Summit Supercomputer at Oak Ridge

Today Allinea announced that Oak Ridge National Laboratory has deployed its code performance profiler Allinea MAP in strength on the Titan supercomputer. Allinea MAP enables developers of software for supercomputers of all sizes to produce faster code. Its deployment on Titan will help to use the system’s 299,008 CPU cores and 18,688 GPUs more efficiently. Software teams at Oak Ridge are also preparing for the arrival of the next generation supercomputer, the Summit pre-Exascale system – which will be capable of over 150 PetaFLOPS in 2018.

Oak Ridge to Run ParallWare on Titan

Today Oak Ridge announced approval of a project run ParallelWare from Appentra on the Titan Supercomputer. The project includes an allocation of 50,000 core hours on supercomputer. “ParallelWare is an source-to-source parallelizing compiler for sequential scientific programs. ParallelWare automatically discovers the parallelism available int he input sequential C code, and automatically generates parallel-equivalent C code annotated with OpenMP compiler directives.

Autotune Code from ORNL Tunes Your Building Energy Efficiency

A team at Oak Ridge has developed a set of automated calibration techniques for tuning residential and commercial building energy efficiency software models to match measured data. Their open source Autotune code is now available on GitHub.

DDNtool Streamlines File System Monitoring at Oak Ridge

Over at Oak Ridge, Eric Gedenk writes that monitoring the status of complex supercomputer systems is an ongoing challenge. Now, Ross Miller from OLCF has developed DDNtool, which provides a single interface to 72 controllers in near real time.

Video: Present and Future Leadership Computers at OLCF

In this video from the 2015 OLCF User Meeting, Buddy Bland from Oak Ridge presents: Present and Future Leadership Computers at OLCF. “As the home of Titan, the fastest supercomputer in the USA, OLCF has an exciting future ahead with the 2017 deployment of the Summit supercomputer. Summit will deliver more than five times the computational performance of Titan’s 18,688 nodes, using only approximately 3,400 nodes when it arrives in 2017.”
