Users to Test DataWarp Burst Buffer on Cori Supercomputer


NERSC has selected a number of HPC research projects to participate in the center’s new Burst Buffer Early User Program, where they will be able to test and run their codes using the new Burst Buffer feature on the center’s newest supercomputer, Cori.

Seagate to Lead Sage Storage Project for Exascale Horizon 2020


“We are excited that the H2020 SAGE Project gives us the opportunity to research and move HPC storage into the Exascale age,” said Ken Claffey, vice president and general manager, Seagate HPC systems business. “Seagate will contribute its unique skills and device technology to address the convergence of Exascale and Big Data, with an excellent selection of participants each bringing their own capabilities together to build the future of storage on an unprecedented scale.”

New Paper: Can 3D-Stacking Topple the Memory Wall?

Memory latency depends on the used memory bandwidth, and the memory latency-bandwidth curve has three regions — constant, linear and exponential. Moving from conventional DDRx (upper figure) to high-bandwidth memory solutions (lower figure) will significantly reduce memory latency only for workloads located in theexponential region of the DDRx latency-bandwidth curve.

Can 3D-stacking technology topple the long-standing “memory wall” that’s been holding back HPC application performance? A new paper from the Barcelona Supercomputing Center written in collaboration with experts from Chalmers University and Lawrence Livermore National Laboratory concludes that it will take more than just the simple replacement of conventional DIMMs with 3D-stacked devices.
