Which engine does fishnet use?
What are the requirements?
|Available for||64-bit Intel and AMD||ARMv8 / Silicon|
||build from source|
|FreeBSD||build from source|
- Needs an operating system from around 2016 or later
- Will max out the configured number of CPU cores
- Uses about 64 MiB RAM per CPU core
- A small amount of disk space
- Low-bandwidth network communication with Lichess servers (only outgoing HTTP requests, so probably no firewall configuration required)
Is my CPU fast enough?
Almost all processors will be able to meet the requirement of ~2 meganodes in 6 seconds. Clients on the faster end will automatically be assigned analysis jobs that have humans waiting for the result (the user queue, as opposed to the system queue for slower clients).
What happens if I stop my client?
Feel free to turn your client on and off at any time. By default, the client will try to finish any batches it has already started. On immediate shutdown, the client tries to inform Lichess that batches should be reassigned. If even that fails, Lichess will reassign the batches after a timeout.
Will fishnet use my GPU?
No, Stockfish is a classical alpha-beta engine. The neural network evaluation of Stockfish NNUE works efficiently on CPUs.
Is fishnet secure?
To the best of our knowledge. However you implicitly trust the authors and the
GitHub infrastructure when running with
You can mitigate this by running fishnet as an unprivileged user.
cargo-crev is used to review the
trustworthiness of dependencies.
Is there a leaderboard of contributors?
No, sorry, not publically. It would incentivize gaming the metrics.
Can I autoscale fishnet in the cloud?
There is currently no ready-made solution, but an API for monitoring the job queue status is provided.
