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.

Hybrid Computing: Advantages of Shared and Distributed Memory Combined

March 6, 2014

Shared memory platform + distributed memory platform = hybrid computing. Learn about the various aspects of hybrid computing and modeling in this installment of our blog series.

Plotting Spatial Derivatives of the Magnetic Field

March 5, 2014

Radiology, magnetophoresis, particle accelerators, and geophysics are all areas where it is useful to compute the spatial derivative of the magnetic field or magnetic flux density.

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.

Optimizing Heater Power for Thermal Processing

February 17, 2014

We demonstrate a useful approach for process control modeling and optimization using COMSOL Multiphysics® and the Optimization Module.

A General Introduction to Chemical Kinetics, Arrhenius Law

February 13, 2014

Countless complications and pitfalls make chemical simulations challenging. Here, we give an introduction to chemical kinetics and Arrhenius law to help >>

Analyze Your Simulation Results with Projection Operators

February 12, 2014

Remember making shadow puppets on the wall with your hands? Projection operators, a method for analyzing your simulation data, work in a similar way. Let us explain…

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.
