Presentation Transcript

  1. CDC 6600 Pioneer Supercomputer

  2. Control Data Corporation • Started by founding members of another company, Engineering Research Associates • CDC started selling parts, primarily drum memory, while designing computer systems

  3. Drum Memory

  4. Designing the 6600 • CDC Chief Engineer - Seymour Cray • Design Issues considered • Packaging • Plumbing • Parallelism • Programming • Understanding problems

  5. Architecture of the 6600

  6. Architechture of the 6600

  7. Performance through Parallelism • Simple CPU supported by array of I/O processors • Many common tasks offloaded • CPU devoted to applying operations to memory, rather than managing memory, disks, or I/O • Result – 6600 outperformed other computers 10 to 1

  8. RISC Processors • 6600 was the first RISC type processor • RISC – Reduced Instruction Set Computer • This type of architecture still popular in performance oriented computing.
