Preface

The Teraflop Workbench Project is a collaboration between the High Performance Computing Center Stuttgart (HLRS) and NEC Deutschland GmbH (NEC HPCE) to support the users to achieve their research goals using high performance computing. As part of the Teraflop Workbench, the Teraflop Workshop since 2004 has become a meeting platform for scientists, application developers, international experts, and hardware designers to discuss the current state and future directions of supercomputing with the aim of achieving the highest sustained application performance. The first stage of the Teraflop Workbench project (2004–2008) concentrated on user’s applications and their optimization for the 72-node NEC SX-8 installation at HLRS. During this stage, numerous indi
