Paper Abstract:
|
In this article we present a first time evaluation of a metamorphosic compute resource (MCR) in a real world scenario. During day-time the MCR compute nodes are ordinary office computers, used in a student lab. Thanks to our enhancements, the computers become part of an OpenMosix based compute resource during the night. The single most common reason for partial loss of computing power was students and/or personnel switching off some of the machines in the evening by mistake: something easily solved by e.g. implementing wake on LAN. We also found that less than 1 per mill of all disturbances was non-trivial in nature which clearly indicates the strength of the architecture. |
