I set up an AWS Lambda function that automatically shuts down the instance every night at midnight, just to be safe. Since you pay by the minute, if you forget to shut it down you will continue to pay for the running server. One risk with this approach is forgetting to stop the instance when you are done with it. Now getting the instance running and SSHEngine configured only takes a few seconds, less time than it takes for Chessbase to startup. The script is written in python and can be found here:

Run a script to update the configuration file.Since this is doing the same thing every time, I figured I would just write a script to do it for me. Log into the AWS Console again (if I was logged out).Previously, when I wanted to use the remote chess engine, I would do this: Sounds complex? Not when I just wrote a script that does it for me… The Old and Slow Way of Setup # But one of my goals was to keep costs down, so I just update the configuration file every time.
I need to update the configuration file every time before I try to connect.įor an additional cost in AWS, you could set up an Elastic IP that reserves an IP address for you. It is not a complete chess program, but requires some UCI compatible GUI (like XBoard with PolyGlot, eboard, Jose, Arena, in order to be used comfortably.

Because I am starting the remote server only when I need it, and stopping it when I am done, the IP address of the host changes every time. Thus it is much easier to install (compared to engines using deep convolutional neural networks, such as Leela Chess Zero) and suitable for almost all modern computers. I have looked at these posts too and couldnt solve it: Stockfish and Python. but the engine just freezes the program and thus the GUI is frozen. The need for this SSHEngine setup is now more clear. I tried to create the engine instance and communicate with it. This lets Chessbase use the SSHEngine.exe file as the engine, but behind the scenes that program is looking at a configuration file and connecting to the remote engine over SSH. I wrote a chess engine proxy called SSHEngine. I’ll be using Chessbase as an example, but I think most of them will work the same way. The first thing you will need is a way to connect to the remote server from your chess database.

In this post I’ll talk about how to actually connect and use that engine. The open source "Iced-tea" version of the plugin is still a bit buggy, in particular the browser javajavscript communication layer that the UCI interface feature relies on is particularly buggy in the iced-tea version, and a lot of Linux distributions have this as the default java plugin, so if that is the case on your Ubuntu machine, you'll need to install the official Oracle java plugin.In my previous post about setting up an on-demand cloud-based chess engine, I gave my ideas about how to get this remote server up and running. If you are still having problems after waiting a few seconds for initialisation to complete, please let me know which version of Chrome and java you are using.Īctually I just noticed you are using Ubuntu, so you will also need to make sure you have the official oracle version of the java plugin installed. If this does happen, clicking stop and then go again will usually get the analysis started. Does it help if you wait a few seconds before clicking 'go'? Depending on the machine/engine it can take a few seconds for the enginebrowser connection to initialise, and if 'go' is hit too early before the initialisation has time to complete, the analysis will not appear. a powerful open-source chess engine Whats a chess engine You know when you play a game of chess and choose Play the computer The chess engine. It sounds like you have the setup done ok, but for some reason the analysis is not coming out from the engine. The Play vs computer is based on a java chess engine that runs in the browsers, but you are trying to get stockfish running on your own machine which is the UCI engine feature. The play vs computer, and the UCI engine analysis - which is what you are trying to get working - are two separate features. The Play vs computer is based on a java chess engine that runs in the browsers, but you are trying to get stockfish running on your own machine which is the UCI.
