Graph reduction machine

A graph reduction machine is a special-purpose computer built to perform combinator calculations by graph reduction.

Examples include the SKIM ("S-K-I machine") computer, built at the University of Cambridge Computer Laboratory,¹ the multiprocessor GRIP ("Graph Reduction In Parallel") computer, built at University College London,²³ and the Reduceron, which was implemented on an FPGA with the single purpose of executing Haskell.⁴⁵
