Limits RegistryPUBLIC RECORD
Limits RegistryThe JEDI system at the Jülich Supercomputing Centre in Germany, built on NVIDIA GH200 Grace Hopper superchips, topped the June 2024 Green500 list with an energy efficiency of approximately 72.7 gigaflops per watt on the standard LINPACK benchmark, the highest efficiency recorded on the list at the time. This is a distinct achievement from raw computational speed (tracked separately by the TOP500 list): a system can rank highly on energy efficiency without being anywhere near the fastest system in absolute terms.

This is a distinct achievement from raw computational speed (tracked separately by the TOP500 list): a system can rank highly on energy efficiency without being anywhere near the fastest system in absolute terms.
The highest energy efficiency, measured in double-precision LINPACK performance per watt, recorded by any system ranked on the Green500 list, a distinct metric from the TOP500 list's ranking by raw computational speed.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
