Embracing Relentless Parallelism: Optimize Your Code for Better Performance

In today's computing landscape, harnessing the power of multiple cores is essential. Nels Beckman's insightful presentation at SIGBOVIK 2008 humorously discusses the challenges of parallelization, using relatable analogies like human gestation. He emphasizes how some tasks are inherently difficult to distribute effectively while advocating for "Relentless Parallelism"—a strategy aimed at keeping all processing cores busy. Through engaging examples of Huffman decoding and variable-length prefixes, Beckman introduces codes rewriting rules grounded in mathematical technology, pushing for relentless efficiency in our coding practices.

  14. Some Tasks? Hard to Parallelize

  15. 1 womb = 1 baby in 9 months Example

  16. 2 womb != 1 baby in 4.5 months Example

  17. 2 womb != 1 baby in 4.5 months Example

  18. 2 womb != 1 baby in 4.5 months Example No

  19. 2 womb != 1 baby in 4.5 months Example No Ultra

  20. 2 womb != 1 baby in 4.5 months Example No Ultra Wombs

  21. Example • Huffman Decoding = Human Baby

  22. Example • Huffman Decoding = Human Baby • Variable Length Prefixes

  23. Example • Huffman Decoding = Human Baby • Variable Length Prefixes • Hard to “Divide and Conquer”

  24. Question!!! • How do we utilize those other cores!?!?!?!?! Huff Stuff ? ? ?

  25. Answer??? • Let’s make it RELENTLESSLY PARALELL!!!!!! Huff Stuff ? ? ?

  26. Answer??? • Let’s make it RELENTLESSLY PARALELL!!!!!! Huff Stuff ? ? ? RELENTLESS
