Session 9206: S/390 Linux: The Beginnings of the Dream Machine

In February 2000, Scott Courtney's article "S/390: The Linux Dream Machine" was published on, and raised the level of awareness of mainframe Linux in the general Open Source community.

Session 9202: How Many Linux Systems Can Dance on a Single S/390

The VM operating system allows many hundreds, or even thousands, of Linux images to run simultaneously in their own virtual machines on a single IBM S/390 or zSeries mainframe. In this presentation, created by David Boyes and presented at SHARE 98 by Scott Courtney, we examine what happens when the number of running Linux images is pushed to its extreme limits. A history of the widely-known "Test Plan Charlie" and lesser-known "Test Plan Omega" demonstrations is included in the presentation. PDF
