16-Petaflop Supercomputer on Hold to Wait for ‘Skylake’ Xeon

The UK’s Met Office puts the third of three Cray supercomputers on hold to wait for greater power from the next-gen Xeon sometime in 2017. The British weather service has announced it will delay installation of the last of a three-supercomputer package it bought last year so it can get …

Multicore Optimization Realized: Tuning for Intel MICs

As the number of cores available to programmers has grown, so have the opportunities to exceed results expected by Moore’s Law. Servers routinely offer dozens of Xeon cores and the ability to run hundreds of simultaneous threads on Xeon Phi coprocessors. The question is how best to parallelize and optimize …

Offload Your Code to Your GPU: How to Get Started

At the time of this writing, most desktop computers have video cards with multiple processor cores that support advanced graphics. But most of the time they are idle, just waiting for a graphically intense program to run. In the past, it has taken a bit of effort to take advantage …

Parallel Algorithm Boot Camp

I have spent a good bit of time writing about parallelization using Parallel Studio. My blogs have included using OpenMP, Cilk, and Threaded Building Blocks. And while these are important because they provide an opportunity to parallelize code that is normally sequential, it is now time to look into algorithms …

NASA Explores How ‘Hot Jupiters’ Are Formed

Researchers are using a NASA supercomputer to simulate massive planets and their stars in an effort to better understand how they are formed. These giant stars, called “hot Jupiters,” are about the same size as Jupiter, but they are much closer to their host stars, meaning they have faster orbits …

Stanford, Army Solve Billions of Equations in Minutes

A Stanford professor and his research team believe they have set a computational record by using a supercomputer to solve more than 10 billion equations in just over three minutes. Stanford professor Charbel Farhat and his team at the Army High Performance Computing Research Center (AHPCRC) recently used Excalibur, a …

Get Best Memory-Consumption Scalability of Intel MPI Library

High-performance computing applications tend to use most of the available memory on a node, making it difficult to estimate the memory consumption of MPI libraries. But there are ways to estimate memory consumption and ways to fine-tune the Intel MPI Library settings to reduce the memory footprint. For example, users …
