HPC People on the Move – Long, Hot Summer Edition

Dr. Lewey Anton

Dr. Lewey reports on who’s jumping ship and moving on up in high performance computing.

Intelligent Light Scales CFD Code to 64,000 Cores

Today Intelligent Light announced breakthrough CFD scalability running the AVF-Leslie combustion simulation code on up to 64,000 cores on NERSC supercomputers.

Hunting Supernovas with Supercomputers

Caltech researchers are using NERSC supercomputers to search for newly born supernovas. The details of their findings appear May 20 in an advance online issue of Nature.

Fortran Still Going Strong

Fortran still going strong. NERSC estimates that over half the hours on their systems are used by Fortran codes. This is quite amazing, given that Fortran first appeared about 60 years ago.

NERSC to Install Cori Phase 1 Supercomputer this Summer

Today NERSC announced that their Cori Phase 1 system will be the first supercomputer installed in the new Computational Research and Theory Facility, which is now in the final stages of construction at LBNL. Expected to be delivered this summer, the Cray XC40 supercomputer will be powered by Intel Haswell processors and Cray’s DataWarp burst buffer technology.

Preparing for Advanced Manycore Architectures – and Implications on the Interconnect

Katie Antypas,
Services Department Head, National Energy Research Scientific Computing Center, Lawrence Berkeley National Laboratory

In this video from the 2015 OFS Developer’s Workshop, Katie Antypas from LBNL describes preparations for the Cori supercomputer. “We need to emphasize here that the Knights Landing processor is self-hosted, and so that means it’s not an accelerator. It’s not a coprocessor and the particular kernel processor that will be having for NERSC-8, will have more than 60 cores and it will have multiple hardware threads for the core. That’s a lot, right? Having 60 cores per node with multiple hardware threads. That a significant increase from both our Hopper and Edison system, which has 24 cores each.”

Saul Perlmutter presents: Data, Computation, and the Fate of the Universe

“I think it’s a very interesting period for human cosmology because it’s a golden age in which every ten years we learn breathtaking new parts of the story. We have never before been able to do that in human history – to have the chance we have now to look at and understand the universe we live in.”

NERSC Honors HPC Achievement Award Winners

nersc2

This week NERSC announced the winners of its third annual HPC Achievement Awards. The awards recognize NERSC users who have demonstrated an innovative use of HPC resources to solve a scientific problem or whose work has had an exceptional impact on scientific understanding or society.

Cray CEO Peter Ungaro Takes the ALS Ice Bucket Challenge

In this video, Cray CEO Peter Ungaro takes the ALS Ice Bucket Challenge. As is the nature of these things, he goes on to challenge Cray CTO Steve Scott, Intel’s Raj Hazra, and NERSC’s Sudip Dosanjh.

NERSC Announces Exascale Science Application Program Projects

NERSClogocolor

NERSC has accepted a selection of key DOE science projects into its NERSC Exascale Scientific Applications Program, a collaborative effort in which NERSC will partner with code teams to prepare for the NERSC-8 Cori manycore architecture. NESAP represents an important opportunity for researchers to prepare application codes for the new architecture and to help advance […]
