Goals

  • Combine BoS-prefetching with CoopRT and check how they interact.

What I worked on

  • Get the BoS-prefetcher up and running by pruning through the legacy BoQ-prefetcher codebase.

Key Insights

  • None

Questions / Confusions

  • CoopRT introduces a mechanism where it pushes the a node from the TOS of one thread to the traversal stack of another thread. Can I justify the BoS prefetcher using a similar implementation?

Ideas / Hypotheses

  • No new ideas today ;)

Papers / Resources

  • None

Next Steps

  • Get the numbers for BoS prefetcher for both 128x128 and 256x256 configuration for all scenes.
