The [[CDC 6600]], generally considered the first supercomputer in the world, ran the [[Chippewa Operating System]], which was then deployed on various other [[CDC 6000 series]] computers.<ref name=Vardalas >''The computer revolution in Canada'' by John N. Vardalas 2001 ISBN 0-262-22064-4 page 258</ref> The Chippewa was a rather simple [[job control block(computing)|job control]] oriented system derived from the earlier [[CDC 3000]], but it influenced the later [[CDC KRONOS|KRONOS]] and [[CDC SCOPE (software)|SCOPE]] systems.<ref name=Vardalas /><ref>''Design of a computer: the Control Data 6600'' by James E.

The first [[Cray 1]] was delivered to the Los Alamos Lab without an operating system, or any other software.<ref name=Flamm >''Targeting the computer: government support and international competition'' by Kenneth Flamm 1987 ISBN 0-8157-2851-4 pages 81-83</ref> Los Alamos developed not only the application software for it, but also the operating system.<ref name=Flamm /> The main timesharing system for the Cray 1, the [[Cray Time Sharing System]] (CTSS), was then developed at the Livermore Labs as a direct descendant of the [[Livermore Time Sharing System]] (LTSS) for the CDC 6600 operating system from twenty years earlier.<ref name=Flamm />
