The Blue Gene Approach – A Path Finder to Petascale Supercomputing • Design Driven by Integration, Power, and Technology Considerations: • Multiple modest cores running at reduced voltage and frequency (P = CV 2 F) on a single chip rather than one high-performance processor. – Single system-on-chip nodes reduce system complexity – System-on-chip reduces power as interconnects are shortened and chip crossings removed. – Embedded DRAM shortens latency, reduces application stalling, simplifies design. – Enables high density, further reducing interconnect distances and saving facility cost. • Stress Simplicity • Choose the right areas to innovate (networks, memory system, clocking, power regulation and distribution) • Note: There is NO exotic or bleeding edge technology in Blue Gene • Enable familiar, standard programming model and mature compiler support. • Linux environment, MPI (standard messaging interface), and OpenMP (standard shared memory parallelism) • Close attention to RAS (reliability, availability, and serviceability) at all system levels. • One of the biggest challenges • Infused throughout Blue Gene design Deep Computing has the Green Gene ! © 2008 IBM Corporation 2008/6/11 5
