Precision and Reproducibility in Computing

Posted on by Paul Shirkey
Run-to-run reproducibility in computing is often assumed as an obvious truth. However software running on modern computer architectures, among many other processes, particularly when coupled with advanced performance-optimized libraries, is often only guaranteed to produce reproducible results only up to a certain precision; beyond that results can and do vary run-to-run. Reproducibility is inte...

Special Functions

Posted on by Paul Shirkey
Motivated by the need of some special functions when writing signal processing code for NMath, we decided to add a suite of special functions to be included in NMath 6.1. While the field of special functions is vast [1], our 41 functions cover many of the most commonly needed functions in physics and engineering. This includes the gamma function and related functions, Bessel functions, elliptic i...

Distributing Parallel Tasks on Multiple GPU’s

Posted on by Paul Shirkey
In this post I'm going demonstrate how to use the Task Parallel Library with NMath Premium to run tasks in parallel on multiple GPU's and the CPU. Back in 2012 when Microsoft released .NET 4.0 and the System.Threading.Task namespace many .NET programmers never, or only under duress, wrote multi-threaded code. It's old news now that TPL has reduced the complexity of writing threaded code by provi...
