I am looking for references to literature on Barrel Processors. I have seen the original articles on the CDC6600 Peripheral Processors. I am also interested in information on the Operating System for the CDC6600. I'd like any references to articles that describe the OS and how work was scheduled onto the Peripheral Processors. Finally, I am looking for any references to articles about the old Honeywell 1648 time-sharing system with particular information about the scheduler and how it assigned work to the Job Processors. Thank you. -- Michael Sporer uunet!stardent!sporer Stardent Computer Inc sporer@stardent.com

Said micros had memory cycles which really used the bus only during the second half of the clock cycle (though the address would come out late in the first half). As a result, by using memory twice as fast as normal, and by running two micros on opposite clock phases, you could get a "2-CPU multiprocessor" for not much more than the cost of one. -Rob ----- Rob Warnock, MS-9U/510 rpw3@sgi.com rpw3@pei.com Silicon Graphics, Inc.

In the Supercomputing 88 proceedings there are a number of articles on Horizon, a successor to HEP and predecessor of the Tera machine. -David David Smitley Supercomputing Research Center 17100 Science Drive Bowie, MD 20715 smitley@super.org
