I β€˜be been vibe coding a path tracer from scratch and I am impressed with the speed and quality of the code. Last time I tried to do this (about 1 year ago) it was a complete disaster. Today, in less than 4h I have a workable basic path tracer with GPU acceleration (kokkos) and ANARI support

Fresh off the plane in St. Louis and ready to dive into the #SC25 whirlwind this week! If you’re around and want to chat all things #HPC, visual magic, or just share a beer and a few good stories, let’s make it happen.

Feel free to ping me if you’re around. Looking forward to it!

Pinning threads properly can save you more time than upgrading your cluster. OMP_PLACES matters.

Next week, we welcome around 12 brilliant interns to the lab, and I couldn’t be more excited!

Summer at Argonne is always buzzing with fresh energy, bold ideas, and new perspectives. Can’t wait to see what this incredible group brings to the table!

Honored to be named a Vanguard of HPC + AI by insideHPC.

At Argonne’s ALCF, I get to explore how humans and machines collaborateβ€”through XR, in-situ viz, and tools that bring data to life.

Dancing on the bleeding edge of scienceβ€”and loving every step.

New week, new magic from OpenAI: GPT-4o can now create and edit images right inside ChatGPT.

And guess what? It finally gets text rightβ€”no more blurry fonts or accidental gibberish. Just describe what you imagine, and it brings it to life. πŸ’«

I gave it a tryβ€”check out what I made below! πŸ‘‡

Drake's lawsuit claims that Twitter and YouTube posts are being mean to him. They cited over 30 comments from YouTube as proof. This is the most pathetic thing ever done in Hip Hop history.
