Jane Street allocates GPUs by live internal auction — anyone can kill your job

AccBalanced · x · 2026-08-23

Jane Street doesn't allocate its GPU cluster by committee. It runs a live internal auction where researchers bid against each other for compute — no approvals, no allocation meetings, no guardrails. The cluster is globally readable and writable: anyone can see what others are running and even kill anyone else's job. The freedom has backfired at least once, when a researcher adjusting his job's bids in a Jupyter notebook ran the command without arguments and wiped out everyone's bids cluster-wide.
