a [https://en.wikipedia.org/wiki/Grid_computing grid computing] [https://en.wikipedia.org/wiki/Computer_cluster cluster] chess program by [[Kai Himstedt]] incorporating [[Ginkgo]] by [[Frank Schneider]] as primary search engine, and [[Crafty]] by [[Robert Hyatt]] as proxy engine, which performs no tree search but has a role to control the optimistic [[Pondering|pondering]] <ref>[[Kai Himstedt]] ('''2005'''). ''An Optimistic Pondering Approach for Asynchronous Distributed Games''. [[ICGA Journal#28_2|ICGA Journal, Vol. 28, No. 2]]</ref> with distributed worker clients <ref> [[Kai Himstedt]] ('''2012'''). ''GridChess: Combining Optimistic Pondering with the Young Brothers Wait Concept''. [[ICGA Journal#35_2|ICGA Journal, Vol. 35, No. 2]]</ref>. Supported by [[Timo Haupt]], GridGinkgo played the [[WCCC 2016]] in [https://en.wikipedia.org/wiki/Leiden Leiden] on a cluster of 30 [[Intel]] and [[AMD]] [[x86-64]] PCs with 224 processor cores, and came in fourth with 4/10 in that extraordinary strong field. At the [[WCCC 2018]] in [https://en.wikipedia.org/wiki/Stockholm Stockholm], GridGinkgo became runner-up, losing the play-off versus [[Komodo]].
