Tackle the Challenges of Parallel Programming in the Visual Effects Industry In Multithreading for Visual Effects, developers from DreamWorks Animation, Pixar, Side Effects, Intel, and AMD share their successes and failures in the messy real-world application area of production software. They provide practical advice on multithreading techniques and visual effects used in popular visual effects libraries (such as Bullet, OpenVDB, and OpenSubdiv), one of the industry's leading visual effects packages (Houdini), and proprietary animation systems. This information is valuable not just to those in the visual effects arena, but also to developers of high performance software looking to increase performance of their code. Diverse Solutions to Solve Performance Problems After an introductory chapter, each subsequent chapter presents a case study that illustrates how the authors used multithreading techniques to achieve better performance. The authors discuss the problems that occurred and explain how they solved them. The case studies encompass solutions for shaving milliseconds, solutions for optimizing longer running tasks, multithreading techniques for modern CPU architectures, and massive parallelism using GPUs. Some of the case studies include open source projects so you can try out these techniques for yourself and see how well they work.

Two reports are published in this volume: excavations in 2003 at Blenheim Farm, Moreton-in-Marsh (by Jonathan Hart and Mary Alexander) and excavations in 2004 at 21 Church Road, Bishop's Cleeve (by Kate Cullen and Annette Hancocks). Significant remains recorded at Moreton-in-Marsh include a Middle Bronze Age settlement of four post-built circular structures partly enclosed by a segmented ditch, and a series of medieval fields and paddocks with a possible sheepcote structure. A Middle Palaeolithic handaxe was also recovered. The Iron Age and medieval remains recorded at Bishop's Cleeve add to our understanding of past settlement in and around the village, where extensive development has resulted in a number of significant excavations in recent years.

Two reports are published in this volume: excavations in 2004 at Henbury School, Bristol (by Derek Evans, Neil Holbrook and E.R. McSloy) and excavations in 2005 at Hewlett Packard, Filton, South Gloucestershire (by Kate Cullen, Neil Holbrook, Martin Watts, Anwen Caffell and Malin Holst). Excavations in 2004 at Henbury School, Bristol, revealed the truncated remains of 21 inhumation burials, making a total of 28 burials recorded at the site since 1982. Of these, 24 burials formed a dispersed cemetery of crouched inhumations, the vast majority of which were aligned north/south and lay on their left sides, with equal numbers of males and females (where sex could be determined) and only one child. Poor bone survival rendered radiocarbon dating invalid, and the cemetery is dated by only one grave good: a finger ring from the mid to late Iron Age. However, the cemetery clearly pre-dated a later rectangular enclosure of very late Iron Age (early 1st-century AD) date. Crouched inhumations from the later Iron Age are known from the region but usually from pits or scattered, so the presence of this cemetery at Henbury is significant. Inhumation cemeteries of this date are rare in Western Britain, although they may have been quite widespread. Despite the dearth of surviving features within the subsequent enclosure, the scale of the ditches suggests it was a farmstead, and environmental evidence hints at both livestock rearing and cereal cultivation. Subsequent Roman activity was clearly intensive, and included a further four burials; although difficult to interpret, it adds to a substantial amount of evidence for Roman activity to the north-west of Bristol. Excavations in 2005 at Hewlett Packard, Filton, revealed the truncated remains of 51 inhumation burials within an isolated post-Roman cemetery. All of the burials were extended and east-west aligned, and were arranged in rows and groups. The tradition of east/west-aligned graves is a common late Roman and post-Roman practice, and these were not necessarily Christian. The largest group comprised 24 burials clustered around a central grave that contained an unusual skeleton and evidence for a distinctive burial rite. Overall there were slightly more females than males (where sex could be determined) and ten children. Adult stature could only be calculated in a few cases; males were generally taller that the early medieval average, females shorter. No grave goods were recovered, but four radiocarbon dates obtained from human bone suggest a period of use sometime between the 5th and 7th centuries AD. There was no evidence for contemporary settlement within the immediate vicinity. Other post-Roman cemeteries that are culturally distinct from Anglo-Saxon influenced burials are known from the region. The absence of Anglo-Saxon cemeteries in South Gloucestershire suggests this area remained under British control in the 5th and 6th centuries. The abandonment of this cemetery may have been the result of changes in the religious landscape once the area finally came under Saxon control in the late 7th century.

In The Royal Marines and the War at Sea 1939-45 military and naval historian Martin Watts records how marines fought at sea, their relationship with the Royal Navy, and the overall contribution they made to victory in the Second World War. Combining personal narrative with strategical, tactical and technical analysis, this book is centred on the career of the author's great-uncle, Colour Sergeant Albert 'Nobby' Elliott, who saw active service in the Atlantic, Mediterranean, Arctic and Indian Oceans. He was Mentioned in Despatches at the Second Battle of Sirte, took part in Operation Torch, and was a gun layer in HMS Jamaicawhen she took part in the sinking of the German battleship Scharnhorston Boxing Day 1943. Nobby finished the war recovering Allied prisoners of war from the south-west Pacific, and was present at the surrender of Japanese forces while on board HMS Glory.

This groundbreaking new core textbook encourages students to take a more critical approach to the prevalent assumptions around the subject of macroeconomics, by comparing and contrasting heterodox and orthodox approaches to theory and policy. The first such textbook to develop a heterodox model from the ground up, it is based on the principles of Modern Monetary Theory (MMT) as derived from the theories of Keynes, Kalecki, Veblen, Marx, and Minsky, amongst others. The internationally-respected author team offer appropriate fiscal and monetary policy recommendations, explaining how the poor economic performance of most of the wealthy capitalist countries over recent decades could have been avoided, and delivering a well-reasoned practical and philosophical argument for the heterodox MMT approach being advocated. The book is suitable for both introductory and intermediate courses, offering a thorough overview of the basics and valuable historical context, while covering everything needed for more advanced courses. Issues are explained conceptually, with the more technical, mathematical material in chapter appendices, offering greater flexibility of use.
