How to Use the Cluster Sweep Node in COMSOL Multiphysics®

June 12, 2018

Keep your cluster admin happy by using the Cluster Sweep node in COMSOL Multiphysics® to optimize the parallelization of parametric computations on clusters.

Running COMSOL Multiphysics® with Cloud Computing

February 20, 2015

You want to run some HPC simulations in COMSOL Multiphysics®, but don’t have access to a cluster. What can you do? One option is cloud computing. Learn more about it here >>

Why Haven’t CPU Clock Speeds Increased in the Last Few Years?

November 13, 2014

Did you ever notice that around the year 2005, the top speed of high-end processors plateaued at 4 GHz? We discuss why this happened and why CPU speeds haven’t increased much since.

Building a Beowulf Cluster for Faster Multiphysics Simulations

April 11, 2014

In 1994, NASA researchers built a small cluster of normal workstations. They called this parallel workstation Beowulf. Today, “Beowulf cluster” describes clusters built from normal workstations.

Added Value of Task Parallelism in Batch Sweeps

March 20, 2014

You can use batch sweeps to improve your modeling performance when you reach limitations in parallel computing. Learn how in this part of our Hybrid Modeling blog series.

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

February 20, 2014

In a follow-up to our post on shared memory computing, we discuss another 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

Remember 20 years ago, when the TOP500 list was dominated by vector processing supercomputers equipped with up to a thousand processing units? Let’s take a walk through history to the future.
