PRACE 2011 prototype, 1TF/kW efficiency ratio. process debugging of HW and SW on multi-socket, multi-chipset, multi-GPUs, multi-rail (IB). pro demeanorion/binding. In background: [c/nc] HT topologies, I/O surgical process implications, performance counters, NIC/GPU thingumabob interaction with processors, SW stacks. 12/7/2011 pre-Exascale HPC systems Saudi-Arabian-Arabian Arabian HPC Symposium, Al-Khobar If (HPC==customization) {Heterogeneous HW/SW flexibility;} else {Enterprise solutions;} On the HW side, customization is each(prenominal) about Multi-socket systems, to provide mainframe computing density (ie. accumulate G[FLOP/Byte]/s), and entrepot capacity. Multi-chipset systems, to hook ternary GPUs (to accelerate computation) and NICs (tightly coupled processors/gpus across computing lymph glands). But pass attention, among other things, to [nc/c]HT topologies to avoid data track out of bandwidth (ie. resource limitations) mingled with devices when the HPC action starts pushing to the limits in all directions. 12/7/2011 pre-Exascale HPC systems Saudi Arabian HPC Symposium, Al-Khobar  typesetters incident: break up NFS (RNANETWORKS) oer 4 QDR IB cards FAT inspissation in 4U 8xSix-core @ 2.
