Description

Describe the issue

Hi, thanks for the great work. I had two quick questions:

  1. In the paper, it’s mentioned that retaining top-4096 attention columns achieves 96.4% recall under a 128K context. Could you share more details on how this was implemented? Given that the full attention matrix at this scale would not fit into GPU memory, how did you handle the memory issue during evaluation?

  2. In Appendix C.3 (Single A100 Implementation Details), would it be possible to release the test code used for the 1M-token inference on a single A100?

Thanks again!
