Benchmarking CPUs at Shell

Ronald Cogswell from Shell gave this talk at the Rice Oil & Gas Conference. “In this presentation we will compare the benchmarking results from the latest 2 generations of CPU hardware from AMD and Intel. The benchmarks were conducted using proprietary Seismic kernels as well as known open source benchmarks. The study focused on memory bandwidth, flops and overall performance and provides results of real-world production Seismic workloads.”


In this special guest feature, Gilad Shainer from Mellanox Technologies writes that the new GPCNeT benchmark is actually a measure of relative performance under load rather than a measure of absolute performance. “When it comes to evaluating high-performance computing systems or interconnects, there are much better benchmarks available for use. Moreover, the ability to benchmark real workloads is obviously a better approach for determining system or interconnect performance and capabilities. The drawbacks of GPCNeT benchmarks can be much more than its benefits.”

Benchmarking MPI Applications in Singularity Containers on Traditional HPC and Cloud Infrastructures

Andrei Plamada from ETH Zurich gave this talk at the hpc-ch forum on Cloud and Containers. “Singularity is a container solution that promises to both integrate MPI applications seamlessly and run containers without privilege escalation. These benefits make Singularity a potentially good candidate for the scientific high-performance computing community. However, the performance overhead introduced by Singularity is unclear. In this work we will analyze the overhead and the user experience on both traditional HPC and cloud infrastructures.”

Video: Scientific Benchmarking of Parallel Computing Systems

In this video, Torsten Hoefler from ETH Zurich presents: Scientific Benchmarking of Parallel Computing Systems. “Measuring and reporting performance of parallel computers constitutes the basis for scientific advancement of high-performance computing. Most scientific reports show performance improvements of new techniques and are thus obliged to ensure reproducibility or at least interpretability. Our investigation of a stratified sample of 120 papers across three top conferences in the field shows that the state of the practice is not sufficient.”

Video: Benchmarking as the Answer to HPC Performance and Architecture Questions

“This presentation offers an impartial look at benchmarking of HPC systems by Andrew Jones (@hpcnotes), NAG VP Strategic HPC Consulting & Services. This is described as a must-see for anyone involved in high performance or scientific computing.”

All about Baselining: RedLine Explains HPC Performance Methodology

In HPC we talk a lot about performance, and vendors are constantly striving to increase the performance of their components, but who out there is making sure that customers get the performance that they’re paying for? Well, according to their recently published ebook, a company called RedLine Performance Solutions has adopted that role with gusto.

Call for Papers: International Conference on HPC & Simulation in Genoa

The International Conference on HPC & Simulation has issued its Call for Papers. Also known as HPBench, the event place in July 17-21 in Genoa, Italy. “Benchmarking is an essential aspect of modern computational science, and as such, it provides a means for quantifying and comparing the performance of different computer systems. With a large combination of aspects to benchmark, all the way from the capability of a single core, to cluster configuration, and to various software configurations, the benchmarking process is more of an art than science. However, the results of this process, drive modern science and are vital for the community to draw sensible conclusions on the performance of applications and systems.”

Video: Brendan Gregg Looks at Tools & Methodologies for Linux System Performance

In this video from the 2016 Percona Data Performance Conference, Brendan Gregg, Senior Performance Architect from Netflix presents: Linux Systems Performance. “Systems performance provides a different perspective for analysis and tuning, and can help you find performance wins for your databases, applications, and the kernel. However, most of us are not performance or kernel engineers, […]

Radio Free HPC Previews Tutorials at SC15

In this podcast, the Radio Free HPC team previews three of the excellent Tutorial sessions coming up at SC15. “The SC tutorials program is one of the highlights of the SC Conference series, and it is one of the largest tutorial programs at any computing-related conference in the world. It offers attendees the chance to learn from and to interact with leading experts in the most popular areas of high performance computing (HPC), networking, and storage.”
