New Stability Results for Multiserver-job Models via Product-form Saturated Systems

Isaac Grosof, Mor Harchol-Balter, Alan Scheller-Wolf. MAMA workshop at SIGMETRICS 2023.

[paper] [old full version] [old full arxiv] [talks]

The old version of the above paper was not accepted, with good reason. Much of the old paper was devoted to rederiving standard results on the saturated system, which we missed in our literature review. However, the product form result is still novel, and that’s the focus of the MAMA version.
