Recommendations for High-Performance Computing on OpenStack

Over the last year, I’ve been working on use cases with high-performance computing (HPC) on OpenStack. In this post, I’ll offer some considerations about hosting high performance and high-throughput workloads. First, let’s start with the three types of architectures that can be used when hosting...

8 Ways Linux Is Taking Over the World

The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. It’s a 17-mile long circular tube that’s buried 175 meters below the French-Swiss border near Geneva. It’s common knowledge that the facility has been resounding success from a scientific perspective. But...

Quantum Mechanics Could Solve Cryptography's Random Number Problem

Peter Bierhorst’s machine is no pinnacle of design. Nestled in the Rocky Mountains inside a facility for the National Institute of Standards and Technology, the photon-generating behemoth spans an entire building. Its lasers, mirrors, and lenses are split among three laboratories, two of them at...

Removing the Storage Bottleneck for AI

If the history of high performance computing has taught us anything, it is that we cannot focus too much on compute at the expense of storage and networking. Having all of the compute in the world doesn’t mean diddlysquat if the storage can’t get data to the compute elements – whatever they might...

A Primer on Nvidia-Docker — Where Containers Meet GPUs

Traditional programs cannot access GPUs directly. They need a special parallel programming interface to move computations to GPU. Nvidia, the most popular graphics card manufacturer, has created Compute Unified Device Architecture (CUDA), as a parallel computing platform and programming model for...

Supercomputing under a New Lens: A Sandia-Developed Benchmark Re-ranks Top Computers

A Sandia National Laboratories software program now installed as an additional test for the widely observed TOP500 supercomputer challenge has become increasingly prominent. The program’s full name — High Performance Conjugate Gradients, or HPCG — doesn’t come trippingly to the tongue, but word is...

The Engine of HPC and Machine Learning

There is no question right now that if you have a big computing job in either high performance computing – the colloquial name for traditional massively parallel simulation and modeling applications – or in machine learning – the set of statistical analysis routines with feedback loops that can do...

Fluid HPC: How Extreme-Scale Computing Should Respond to Meltdown and Spectre

The Meltdown and Spectre vulnerabilities are proving difficult to fix, and initial experiments suggest security patches will cause significant performance penalties to HPC applications. Even as these patches are rolled out to current HPC platforms, it might be helpful to explore how future HPC...
