Description

A brief description is available from the ACM 1980 tournament booklet [6] :
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, uses alpha-beta algorithm and iterative deepening. On the Cray-1, the Lanks say the program examines 4,000 nodes per second. This is its first ACM tournament.
