Howdy
Phew, just went swimming in 7C (44.6F) water. No need for coffee after that. My fingers are still a little numb, so please excuse any typos.
Anyway, here's the issue.

How to Optimize a CUDA Matmul Kernel for cuBLAS-like Performance: a Worklog

Published: 30 December 2022
Tags: gpu, optimization

Simon Boehm discusses how to optimize a CUDA matrix multiplication kernel for performance.
Some highlights:

  • Simon begins with a naive kernel and then applies optimizations to improve performance
  • The goal is to get within 80% of the performance of cuBLAS, NVIDIA's official matrix library
  • Dives into coalescing global memory accesses, shared memory caching, occupancy optimizations, and more

HTTP/3 Prioritization Demystified

Published: 23 December 2022
Tags: http, optimization, web

Robin Marx does a deep-dive on HTTP resource prioritization.
Some highlights:

  • HTTP resource prioritization is a concept for HTTP/2 and HTTP/3 that allows for multiple requests to be sent at the same time on one connection
  • The priority is determined by the browser and can be tweaked with the new attribute "Priority Hints"
  • The importance of prioritization lies in its ability to improve performance by loading resources more efficiently

Untangle: Solving problems with fuzzy constraints

Published: 1 January 2023
Tags: graphics, logic

Szymon Kaliski, Marcel Goethals, and Mike Kluev explore solving logic problems with fuzzy constraints
Some highlights:

  • Untangle is "a tool that can help us think through ill-defined problems, understand compromises, and learn about what kind of questions to ask"
  • Not super in-depth on the programming side of things, but an interesting study on how to approach a solving a problem
  • It's basically a look into how a theorem prover can be adapted for more "human" inputs

How did I do?

* Amazing
* Articles not relevant to me
* Articles were relevant, but badly written
* Summaries told me everything I wanted to know
* I like turtles
