[Forwarded Content] The author secured 5th place in the GPU MODE qrv2 competition with a batched QR decomposition kernel that is roughly 280x faster than torch.geqrf on the B200.
They also mentioned their autoresearch swarm ran about 2000 experiments in two weeks. The full writeup covers:
- Householder QR algorithm concepts
- Kernel optimization techniques
- A glimpse into "agentic kernel research" in 2026
