TCEC S13 Issues

For TCEC Season 13, division 3, LC0 performed much worse than expected, but we do not know the cause yet. This page summarizes the issues.

Issues:

• TCEC server is getting less NPS than expected. We expect ~26K from startpos, but only get 22K (source: jjosh in Discord).
• In div4, TCEC GPUs were overheating. For div3 fans were set to 100%, but we still observe lower than expected NPS.
• Time management settings seem to have lc0 play too quickly in the opening.
• While investigating differences between TCEC build and v0.16 build, crem found a bug. It doesn't seem likely this bug can explain what is going on though.
