HPC People on the Move: Michael Feldman and John Kirkley Leave Tabor Communications

By Lewey | Published February 11, 2013

It’s me again–Dr. Lewey Anton. I’ve been commissioned by insideHPC to track HPC People on the Move. It has been a while since I’ve posted, but there are some interesting developments today.

Michael Feldman, long-time editor of HPCWire has joined Intersect360 Research as a Senior Analyst.

Having worked closely with Michael for the past six years, I can say with confidence what great insights he brings to the HPC community,” said Addison Snell, CEO of Intersect360 Research. “Michael is already well-respected across the industry. He’s going to add a lot of value for our clients.”

Intersect360 put out this Press Release on their new analyst today. As you may recall, Intersect360 Research was formed when Addison Snell and Chris Willard left Tabor Research, a division of Tabor Communications, to form their new independent analyst research group.

Feldman leaves HPCWire in the capable hands of Richard Brandt, a seasoned Silicon Valley journalist who is new to the HPC space.

In related news, John Kirkley, former editor of the Digital Manufacturing Report, has left Tabor Communications to reboot Kirkley Communications.

I’m back at the helm of Kirkley Communications, my 25 year-old marketing communications company specializing in high tech editing and writing with an emphasis on HPC and Advanced Manufacturing.”

We wish Feldman and Kirkley the best in their new roles.

John Shalf Moves to CTO Role at NERSC for Exascale Research

By Lewey | Published December 5, 2012

John Shaff, one of our celebrated Rock Stars of HPC, has been appointed CTO at NERSC. Shalf will also continue to serve in his current role as head of the Computer and Data Sciences Department in Berkeley Lab’s Computational Research Division (CRD).

NERSC is the primary HPC facility for scientific research sponsored by theDOE’s Office of Science. As Chief Technology Officer, Shalf will help NERSC develop a plan to achieve exascale performance.

A key goal of DOE’s exascale program is to develop high performance scientific computers that deliver a thousand times the performance of today’s most powerful computers at all scales, while using less than twice the power, by the end of the next decade. The demands of energy efficiency are driving deep changes that will change the way we do computing at all scales, not just exascale. NERSC will take an active role to work with industry as a public/private partnership to guide HPC designs and bring the DOE user community along in this time of great transition.”

Video: SpEC Simulation of Black Holes Merging

By RichB | Published July 4, 2011

In this simulation video from the Caltech-Cornell Simulating eXtreme Spacetime project, two black holes merge into one. Images were generated by the Spectral Einstein Code (SpEC) code. To learn more, the International Science Grid This Week blog caught up with Harald Pfeiffer of the Canadian Institute for Theoretical Astrophysics and University of Toronto:

iSGTW: How resource intensive is this code – can it do these simulations overnight on a workstation? Or does it need many hundreds or thousands of CPU-hours?

Pfeiffer: Binary compact object simulations (where each object can either be a black hole or a neutron star) require 10s to 100s of thousand of CPU-hours per run. For binary black holes, the high cost is mostly determined by the high accuracy required for gravitational wave detectors (these detectors use our simulations as filters to enhance their sensitivity). For neutron star-black hole and neutron star-neutron star binaries the high cost is mostly determined by the large amount of physical effects that need to be simulated: hydrodynamics, magnetic fields, nuclear physics, neutrinos…

Pfeiffer: Given our CPU requirements, we have to be parallel. We use MPI and need a moderately fast interconnect. Infiniband is best, Gigabit Ethernet looses about 20% efficiency. The efficiency loss of gigE is not terrible, and we do run on gig-E clusters, as it is often easier to get compute time there.

iSGTW: What kind of architectures does SpEC run on — has it run on clusters? Grids? Clouds? Supercomputers?

Pfeiffer: Beowulf clusters and supercomputers. We run on in-house clusters at Caltech and CITA, and at various supercomputers (Kraken, Ranger, Lonestar, funded through “NSF Teragrid”, SciNet at Univerity of Toronto, funded by “Compute Canada”).
