  7. 7. ETHERNET JTAG Outline of the Blue Gene/L system software. Only I/O nodes are attached to the Gbit/s Ethernet network, giving 1024x1Gbit/s links to external file servers. The JTAG protocol is used for reading and writing to any address of the 16 KB SRAMs in the BG/L chips. B. E. COMPUTER SEMINAR
  8. 8. Hardware Technologies for petascale computing Special Purpose hardware 5 main categories: • Conventional technologies • Processing in-memory (PIM) designs • Designs based on super conducting processor technology • Special purpose hardware designs • Schemes that use the aggregate computing power of Web-distributed processors Built a family of special-purpose attached processors for performing the gravitational force computations that form the inner loop of N-body simulation problems. B. E. COMPUTER SEMINAR
  9. 9. Blue Gene System Software System Software for the I/O Nodes B. E. COMPUTER SEMINAR
  10. 10. System Software for the Compute Nodes System Management Software Compiler and Run-time Support CIOD in two scenarios: • driven by a console shell (called CIOMAN) • driven by a job scheduler (such as LoadLeveler) Midplane Management and Control System (MMCS) •low level hardware operations • turn on power supplies, monitor temperature sensors and fans, and react accordingly. • configure and initialize IDo, Link and BG/L chips • read and write configuration registers, SRAM and reset the cores of a BG/L chip. • Linux for I/O nodes • BLRTS for compute nodes The custom control library can perform: B.

  12. 12. Blue Gene/L Simulation Environment Trends in Performance of Super Computer Programming methodologies for petascale computing Validating the architecture with application programs •Rapid changes in vendors, architectures, technologies, and system usagein last 50 yrs. •The Top500 list has been updated twice a year since June 1993 BlueGene/L’s unique features are especially appealing for ASCI-scale scientific applications. •A data parallel programming language, •Message passing between sequential processes, •Multithreading B. E. COMPUTER SEMINAR
  13. 13. Blue Gene science applications development B. E. COMPUTER SEMINAR •It is the application platform for the Blue Gene Science program •It serves as a prototyping platform for research into application frameworks suitable for cellular architectures. •It provides an application perspective in close contact with the hardware and systems software development teams
  14. 14. Conclusion/Summary Point •New series of high performance machines •The first small prototypes will be available •Simulation environment •Demonstrate a complete and functional system software environment before hardware becomes available
