Allinea Software is a UK SME providing world-leading development tools and application performance analytics software for high performance computing (HPC). Its headquarters and R&D operation are based in the UK, and it has sales or technical operations in France, Germany, Canada and the USA. It has a customer base throughout the world and includes Europe’s leading HPC centres, universities and HPC industrial users amongst them. Allinea provides integrated profiling and debugging tools which are relied on in fields ranging from climate modelling to astrophysics, and from computational finance to engine design. Its performance analytics software improves the performance and throughput of HPC systems by analyzing the applications that are run on them. Within the SAGE project, Allinea intends to enable strong analysis of the I/O impact on performance for applications within the project – this involves developing analysis interfaces into the I/O system, and into some of the non-“traditional-HPC” applications that are part of this project. By providing development and analysis tools that are enabled for the system, the project will have clear routes to identify performance issues at both application and system level and thereby improve the chances of successful resolution and exploitation of the technology. Allinea will work with the key applications to provide initial performance benchmarking, and will develop the tools required to support the Percipient Storage platform.
