How do organizations use feedback to change their processes, and hence, improve their performance? A small working group isproposing that any organization under control almost always should be using feedback to stabilize and improve their products.We describe the results of applying the Feedback, Evolution, And Software Technology (FEAST) feedback model to ourwork on improving t...

We have previously presented an approach to include graphics processing units as co-processors in a parallel Finite Element multigrid solver called FEAST. In this paper we show that the acceleration transfers to real applications built on top of FEAST, without any modifications of the application code. The chosen solid mechanics code is well suited to assess the practicability of our approach d...

Background: The project was conceived in 1994 following formulation of a FEAST hypothesis. This stated that the software evolution process is a feedback system and must be treated as such to achieve major process improvement. Three self-funding international workshops were held at IC [fea94,5] to explore the hypothesis, with some 40 participants from the UK, Europe and North America at each. Fo...

FEAST (Finite Element Analysis & Solutions Tools) is a Finite Element based solver toolkit for the simulation of PDE problems on parallel HPC systems which implements the concept of ‘hardware-oriented numerics’, a holistic approach aiming at optimal performance for modern numerics. In this paper, we describe this concept and the modular design which enables applications built on top of FEAST to...

Lysosomal storage diseases are metabolic disorders characterized by the accumulation of acidic vacuoles, and are usually the consequence of the deficiency of an enzyme responsible for the metabolism of vesicular lipids, proteins or carbohydrates. In contrast, mucolipidosis type IV (MLIV), results from the absence of a vesicular Ca ( 2+) release channel called mucolipin 1/transient receptor pot...
