Pre-Exascale Systems

Current R&D hands on break away for pre-Exascale HPC systems
Joshua.Mora@AMD.com, WW HPC Agenda Heterogeneous HW flexibility on SW request. PRACE 2011 prototype, 1TF/kW efficiency ratio. Performance debugging of HW and SW on multi-socket, multi-chipset, multi-GPUs, multi-rail (IB). Affinity/binding. In background: [c/nc] HT topologies, I/O performance implications, performance counters, NIC/GPU thingumabob interaction with processors, SW stacks.

If (HPC==customization) {Heterogeneous HW/SW flexibility;} else {Enterprise solutions;}
On the HW side, customization is each(prenominal) about Multi-socket systems, to provide cpu computing density (ie. aggregate G[FLOP/Byte]/s), and memory capacity. Multi-chipset systems, to hook multiple GPUs (to accelerate computation) and NICs (tightly coupled processors/gpus crossways computing lymph glands). But Pay attention, among other things, to [nc/c]HT topologies to avoid racetrack out of bandwidth (ie. resource limitations) between devices when the HPC application starts pushing to the limits in all directions.
