Hewlett Packard Enterprise Showcases Benefits of Code Modernization

“We’ve tailored our story for the HPC developers here, who are really worried about applications and performance of applications. What’s really happened traditionally is that the single-threaded applications had not really been able to take advantage of the multi-core processor-based server platforms. So they’ve not really been getting the optimized platform and they’ve been leaving money on the table, so to speak. Because when you can optimize your applications for parallelism, you can take advantage of these multi-processor server platform. And you can get sometimes up to 10x performance boost, maybe sometime 100x, we’ve seen some financial services applications, or 3x for chemistry types of simulations as an example.”

Student Cluster Teams Learn the Tools of Performance Tuning at SC15

In this video from SC15, Rich Brueckner from insideHPC talks to contestants in the Student Cluster Competition. Using hardware loaners from various vendors and Allinea performance tools, nine teams went head-to-head to build the fastest HPC cluster.

TUM Germany Wins Highest Linpack Award on RSC system at SC15 Student Cluster Competition

Today Russia’s RSC Group announced that Team TUMuch Phun from the Technical University of Munich (TUM) won the Highest Linpack Award in the SC15 Student Cluster Competition. The enthusiastic students achieved 7.1 Teraflops on the Linpack benchmark using an RSC PetaStream cluster with computing nodes based on Intel Xeon Phi. TUM student team took 3rd place in overall competition within 9 teams participated in SCC at SC15, so as only one European representative in this challenge.

Speeding Up Applications at SC15

Software for data analysis, system management, and for debugging other software were be among the innovations on display at SC15 last week. In addition to the software, novel and improved hardware will also be on display, together with an impressive array of initiatives from Europe in research and development leading up to Exascale computing.

Video: Pathscale Compilers Power ARM for HPC at SC15

In this video, Jason Souloglou and Eric Van Hensbergen from ARM describe how Pathscale EKOPath compilers are enabling a new HPC ecosystem based on low-power processors. “As an enabling technology, EKOPath gives our customers the ability to compile for native ARMv8 CPU or accelerated architectures that return the fastest time to solution.”

Who Will Write Next-generation Software?

In this special guest feature from Scientific Computing World, Robert Roe writes that software scalability and portability may be more important even than energy efficiency to the future of HPC. “As the HPC market searches for the optimal strategy to reach exascale, it is clear that the major roadblock to improving the performance of applications will be the scalability of software, rather than the hardware configuration – or even the energy costs associated with running the system.”

OpenACC 2.5 Includes Support for ARM and x86 Processors

The OpenACC Standards Group released the 2.5 version of the OpenACC API specification.

New HPCG Benchmark List Goes Beyond LINPACK to Compare Supercomputers

The High Performance Conjugate Gradients (HPCG) Benchmark list was announced this week at SC15. This is the fourth list produced for the emerging benchmark designed to complement the traditional High Performance LINPACK (HPL) benchmark used as the official metric for ranking the TOP500 systems. The first HPCG list was announced at ISC’14 a year and a half ago, containing only 15 entries and the SC’14 list had 25. The current list contains more than 60 entries as HPCG continues to gain traction in the HPC community.

Society of HPC Professionals to Focus on Cybersecurity at December Conference

The Society of HPC Professionals will focus its 2015 Annual Technical Meeting on the applications of HPC technology to protect against cyberthreats. The one-day ‘HPC in Cybersecurity’ meeting will be held Wednesday, December 2, 2015, at a Schlumberger location in Houston. This event is free and open to all, but advanced registration is required.

Radio Free HPC Reports Live from SC15

In this podcast, the Radio Free HPC team shares their thoughts from SC15 in Austin. Henry is impressed by the increasing presence of FPGAs on the show floor. Dan is really impressed with Allinea Performance Reports profiling tool and how easy it is to use. And Rich sees SC15 as the crossroads that we’ll remember where Intel squared off with the official launch of their Omni-Path Interconnect and Scalable System Framework against the co-design alliance of OpenPOWER with IBM, Mellanox, and Nvidia.
