MACH WORKSHOP ANNOUNCEMENT

                     M A C H    W O R K S H O P
             		October 4 - 5, 1990    
		        Burlington, Vermont


The USENIX Association is pleased to be offering its first workshop on the
Mach operating system.  As Mach becomes increasingly popular in both research
and commercial environments, there are growing needs for up-to-date
information and for those who are involved with the software to meet and talk.
We hope that the variety of papers and formats below will address those needs.
The workshop features a keynote speech by Dr. Richard Rashid of Carnegie-
Mellon University, principal architect of the operating system, as well as
special sessions on virtual memory, Mach as the basis for fault-tolerant
systems, OS internals and performance, and environments and applications.
There will also be a panel discussion of threads models, and a works-in-
progress session for dissemination of information about the very latest Mach
developments.
