Call for Student Cluster Teams at ISC 2016

19786282008_acae70e2f3_n

Today the HPC Advisory Council announced the return of the widely successful HPCAC-ISC Student Cluster Competition in next year’s ISC program of events. In a real-time competition, 11 teams of undergraduate students from around the world will build a small cluster of their own design on the ISC 2016 exhibit floor and race to demonstrate the greatest performance across a series of benchmarks and applications.

Edison Supercomputer Creates 3D Map of Adolescent Universe

Video: Big Data Powers Climate Research at BSC

climate

In this video from the Barcelona Supercomputer Center, Big Data is presented as a key challenge for researchers studying global climate change. “Changes in the composition of the atmosphere can affect the habitability of the planet by modifying the air quality and altering long-term climate. Research in this area is devoted to the development, implementation and refinement of global and regional state-of-the-art models for short-term air quality forecasting and long-term climate predictions.”

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.”

GENCI to Collaborate with IBM in Race to Exascale

world

Today GENCI announced a collaboration with IBM aimed at speeding up the path to exascale computing. “The collaboration, planned to run for at least 18 months, focuses on readying complex scientific applications for systems under development expected to achieve more than 100 petaflops, a solid step forward on the path to exascale. Working closely with supercomputing experts from IBM, GENCI will have access to some of the most advanced high performance computing technologies stemming from the rapidly expanding OpenPOWER ecosystem.”

Arithmetic Intensity of Stencil Operations

F1.large

Applications that use 3D Finite Difference (3DFD) calculations are numerically intensive and can be optimized quite heavily to take advantage of accelerators that are available in today’s systems. The performance of an implementation can and should be optimized using numerical stencils. Choices made when designing and implementing algorithms can affect the Arithmetic Intensity (AI), which is a measure of how efficient an implementation, by comparing the flops and memory access.
