> This makes sense for human players, but the Chess Engines aren't human, so their matches can proceed in parallel.

And if they wanted to they could show multiple matches in parallel. After all that's what happens in the case of a tournament such as the recent Tata Steel tournament. I assume that the issue is that they want to maximize resources for the engines and for that you need to run at most a few engines (and therefore matches) in parallel.

If I read things correctly it's all running on a single server with "only" 96GiB of RAM per engine (https://wiki.chessdom.org/TCEC_Season_Further_information#TC...), running more matches in parallel would be detrimental to the quality of the chess played.
