Home * Engines * GridGinkgo



GridGinkgo, a grid computing 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 with distributed worker clients. Supported by Timo Haupt, GridGinkgo played the WCCC 2016 in 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.
