Description
A brief description is available from the ACM 1980 tournament booklet [6] :
[Cray-1](Cray-1 "Cray-1"), United Computing, Kansas City (512k; 64 bits; 80,000,000 inst/sec)Cube 2.0 is an updated version of Cube 1.1. It executes on either the Cray-1 or on an Honeywell 60/80 provided by Honeywell in Minneapolis. The program is written in [Fortran](Fortran "Fortran"), uses [alpha-beta](Alpha-Beta "Alpha-Beta") algorithm and [iterative deepening](Iterative_Deepening "Iterative Deepening"). On the Cray-1, the Lanks say the program examines 4,000 [nodes per second](Nodes_per_Second "Nodes per Second"). This is its first ACM tournament.
