Welcome to this special publication dedicated to the use of high-performance computing in science. It is brought to you by the team behind Scientific Computing World (SCW) which, for those picking up this magazine at the International Supercomputing Conference in Dresden, is an established title that is at the forefront of software developed specially for use by scientists.

This publication, then, is an extension of that, and a recognition that high-performance computing and science go hand in hand.

In SCW, our rule is that if it’s a scientist or engineer that will choose whether to purchase the software in question, then it is software that is relevant editorially. By the same token, this publication looks at how high-performance computing can be tailored for use specifically by scientists and engineers.

Essentially, the term ‘high-performance computing’ covers anything from the huge, hectare-covering multiple-server supercomputers right down to the desktop level – something that has only become possible relatively recently.

In this magazine, then, we look at several aspects of high-performance computing: firstly, John Murphy talks to Hans Meuer, the founder of the International Supercomputing Conference and a name synonymous with the market for years.

David Robson looks at the emerging trend of using GPUs to relieve some of the processing load from CPUs. This combination of software and hardware is helping scientists and engineers slash the time it takes to complete calculations and process data.

Gemma Simpson brings us up to speed with the increased power now available at the desktop, removing the need to outsource projects to specialist highperformance computing centres.

As well as a guide to some of the highlights of the International Supercomputing Conference, we also talk to a couple of employees at a supercomputing centre about the varied roles they fulfil.
