Computer Architecture: A quantitative approach - Cap4 - Section 8

  1. 1. Multiprocessors and Thread-Level Parallelism Putting it all together: Sun T1 Multiprocessor “ What makes T1 especially interesting is that it is almost totally focused on exploiting thread-level parallelism (TLP) rather than instruction-level parallelism (ILP).” Hennessy and Patterson
  2. 2. <ul><li>Thread level parallelism </li></ul><ul><li>8 processors, 4 threads each </li></ul><ul><li>Six-stage , single-issue pipeline </li></ul>Sun T1 “Niagra” Multiprocessor
  3. 3. Sun T1 “Niagra” Multiprocessor
  4. 4. Sun T1 “Niagra” Multiprocessor
  5. 5. Sun T1 “Niagra” Performance
  6. 6. Sun T1 “Niagra” Performance
  7. 7. Sun T1 “Niagra” Performance
  8. 8. Overall Performance
  9. 9. Overall Performance
  10. 10. Overall Performance
  11. 11. Performance of Multicore Processors: SPEC Benchmarks
  12. 12. Performance of Multicore Processors: SPEC Benchmarks
  13. 13. Performance of Multicore Processors: SPEC Benchmarks
