Description

To achieve the demands of extreme scale and the delivery of exascale, we embrace the computing platform as a whole, not just component optimization or fault resilience. EuroEXA brings a holistic foundation from multiple European HPC projects and partners together with the industrial SME focus of MAX for FPGA data-flow; ICE for infrastructure; ALLIN for HPC tooling and ZPT to collapse the memory bottleneck; to co-design a ground-breaking platform capable of scaling peak performance to 400 PFLOP in a peak system power envelope of 30MW; over four times the performance at four times theenergy efficiency of today s HPC platforms.

Further, we target a PUE parity rating of 1.0 through use of renewables andimmersion-based cooling.We co-design a balanced architecture for both compute- and data-intensive applications using a cost-efficient, modularintegrationapproach enabled by novel inter-die links and the tape-out of a resulting EuroEXA processing unit with integrationof FPGA for data-flow acceleration. We provide a homogenised software platform offering heterogeneous acceleration withscalable shared memory access and create a unique hybrid geographically-addressed, switching and topology interconnectwithin the rack while enabling the adoption of low-cost Ethernet switches offering low-Latency and high-switching bandwidth. Working together with a rich mix of key HPC applications from across climate/weather, physics/energy and life-science/bioinformatics domains we will demonstrate the results of the project through the deployment of an integrated andoperational peta-flop level prototype hosted at STFC. Supported by run-to-completion platform-wide resilience mechanisms,components will manage local failures, while communicating with higher levels of the stack.
