Intro to the What, Why, and How of Distributed Memory Computing

February 20, 2014

In the latest post in this Hybrid Modeling blog series, we discussed the basic principles behind shared memory computing — what it is, why we use it, and how the COMSOL software uses it in its computations. Today, we are going to discuss the other building block of hybrid parallel computing: distributed memory computing.

Intro to the What, Why, and How of Shared Memory Computing

February 6, 2014

A couple of weeks ago, we published the first blog post in a Hybrid Modeling series, about hybrid parallel computing and how it helps COMSOL Multiphysics model faster. Today, we are going to briefly discuss one of the building blocks that make up the hybrid version, namely shared memory computing. Before that, we need to consider what it means that an “application is running in parallel”. You will also learn when and how to use shared memory with COMSOL.

Hybrid Parallel Computing Speeds Up Physics Simulations

January 23, 2014

Twenty years ago, the TOP500 list was dominated by vector processing supercomputers equipped with up to a thousand processing units. Later on, these machines were replaced by clusters for massively parallel computing, which soon dominated the list, and gave rise to distributed computing. The first clusters used dedicated single-core processors per compute node, but soon, additional processors were placed on the node requiring the sharing of memory. The capabilities of these shared-memory parallel machines heralded a sea change towards multicore […]

Photos from the COMSOL 4.4 Launch Event in Silicon Valley

December 9, 2013

In anticipation of the COMSOL 4.4 release, the COMSOL office in Palo Alto decided to try something new. Feeling inspired by the very successful COMSOL Conference in Boston, we held an all-day launch event in Silicon Valley. Here’s a round-up of the event and some of the photos we took.

COMSOL Multiphysics Version 4.4 Released Today

November 27, 2013

You’ve seen glimpses of our new software release at the COMSOL Conference and perhaps engaged in commentary around it in social media. Today marks the official release of COMSOL Multiphysics version 4.4, and you can now learn about the software updates in detail and download it if you are on subscription.

Your Room, from Interior Design to Acoustics

November 26, 2013

I recently stumbled upon a neat tool from Autodesk® called “Autodesk® Homestyler”. It’s surprising to see they have rolled out a tool that is more entertaining than utilitarian, but if a CAD company were to develop something fun for the general population, I suppose an interior design app makes sense. We took it for a test-drive. Here’s how it went.

Street Sign Buckles in the Wind, COMSOL User Takes Home Prize

November 15, 2013

A broken street sign turned into an online contest at the Dutch university TU Delft earlier this month. The TU Delft Webcare Team challenged their social media fans to determine what wind speed led the sign to buckle over — and the winner happens to be a COMSOL user. Here’s how Rob Eling solved the street sign challenge using COMSOL Multiphysics.

COMSOL Conference 2013 Rotterdam Keynotes on Multiphysics Applications

November 6, 2013

The COMSOL Conference 2013 Rotterdam was well-attended and highly informative. The keynotes were the high point of the event, and they were excellent examples of multiphysics applications. The sophistication of the modeling work presented by Alwin Verschueren of Philips Research Laboratories in Eindhoven, the Netherlands, and Holger Ernst and Christian Schröder of mieletec FH Bielefeld, Germany, was truly spectacular and kept all the attendees enthralled.
