Our path: prototypes
• Three testbeds to be deployed at STFC, Daresbury
Testbed 1 Testbed 2 Testbed 3
50 nodes of new 500 nodes and new Test new node and
technology for infrastructure processor technologies
so)ware technologies to test that will ulFmately
development scaling project to Exascale

• Covers three important applicaFon domains
• Climate and weather (LFRic, NEMO, IFS)
• Physics and energy (LBM, Alya, GADGET, AVU-GSR, FRTM, Astronomy image classificaFon)
• Life science and bioinformaFcs (NEST, NeuromarkeFng, InfOli, Quantum E, SMURFF)
• All domains will require exascale compuFng in near future
• ALYA, GADGET, NEMO and Quantum ESPRESSO part of PRACE UEABS
23 Jan 2018 12EuroEXA programming
environment
• ApplicaFons will target portable programming models / communicaFon libraries
• MPI, GPI (GAS programming Interface), Vivado HLS, OmpSs@FPGA, MaxJava, OpenCL (via
SDSoC/SDAccel), OpenStream, and PSyClone
• OpFmizaFon for EuroEXA architecture done by programming environment
• Building on the work in ExaNoDe project
• Greater maturity, especially in FPGA support
• Tuning and opFmizaFon through EuroEXA’s full applicaFons (cf ExaNoDe mini-applicaFons)
• Though work in Weather and Climate is focussed on kernels/mini-apps/dwarves currently
• Partners are currently porFng to x86 clusters and Trenz boards / UltraScale+
• Will migrate to Testbed 1, 2 and 3 as available
