SIRIUS: Next generation multitier data storage and I/O systems
Computational simulation has changed the way that we do science, but there is already a wide gulf between the speed with which we can compute and the rate and capacity with which we can store data. Data storage and management will be the limiting factor for exascale computers and beyond. SIRIUS is a multidisciplinary project conducting research into how this problem can be addressed by best utilising the many different types of storage media that are available on a typical high-performance computer, ranging from high speed in situ memory through to tape. The need to effectively use the entire multi-tier storage hierarchy requires the development and mathematical analysis of new mathematical techniques for data compression and refactoring techniques through to challenges in developing new software infrastructures that enable the computational scientist to utilise the multi-tier hierarchy in a seamless fashion.
