Thoth (operating system)
Thoth is a real-time, message passing operating system (OS) developed at the University of Waterloo in Waterloo, Ontario Canada.
Thoth was developed at the University of Waterloo in Waterloo, Ontario, Canada. The curriculum at Waterloo includes a Real Time Operating Systems course and an associated "Train lab", where students must develop a real-time operating system (RTOS) to control a model track with multiple trains.
In 1972, the B programming language, a derivative of BCPL, was brought to Waterloo by Stephen C. Johnson while on sabbatical from Bell Labs. A new language derived from B, named Eh, was developed at Waterloo. Thoth was written originally in Eh with some assembly language.
Initial development of Thoth occurred on a Honeywell 6050 computer. It was first run on a Data General Nova 2 in May 1976, and was next ported to a Texas Instruments TI990/10 in August 1976.
In October 1976, the University of Waterloo published Laurence S. Melen's Master's Thesis, titled "A Portable Real-Time Executive, Thoth".
Eh was later upgraded, in part with the addition of data types, and renamed Zed. Thoth was then rewritten in Zed.
One of the early principal developers of Thoth was David Cheriton. Cheriton would go on to develop the Verex kernel, and the V-System OS; both influenced by Thoth. Another early developer was Michael Malcolm, who would later found Waterloo Microsystems, Network Appliances, Inc., Blue Coat Systems, and Kaliedescape, several of whose operating systems are believed to have been derived from or influenced by Thoth.
Certain papers describe DEMOS as the inspiration for Thoth. As prior art Cheriton cited Per Brinch Hansen's RC 4000, then listed Thoth, DEMOS, and Accent together as later developments. Other influences on the development of Thoth included Multics, Data General's RTOS, Honeywell GCLS, and Unix. Later references cite Thoth as the original implementation of its particular use of synchronous message passing and multiprocess program structure, which were subsequently applied by other projects.
