A new EPSRC-funded research network has been established by a partnership of the University of Manchester and NAIS. The purpose of the network is to build an interdisciplinary community at the numerical algorithms/HPC interface and thereby provide added value to existing funded research in numerical algorithms and in HPC and its applications. he activities of the network will be - seminars, - graduate courses, - short courses, - a workshop on the interface between NA and HPC, in which HPC users (including HECToR users) will be encouraged to describe the computational requirements of their applications and NA researchers will describe their latest algorithmic developments, - an international workshop, - an industrial workshop, - hosting of international visitors, and - movement of node members (and especially their PhD students and PDRAs) between nodes for visits of a day to a few weeks.
