Abstract
Mixed criticality scheduling algorithms, which attempt to
reclaim system capacity lost to worst-case execution time pes-
simism, seem to hold great promise for multicore real-time
systems, where such loss is particularly severe. However,
the unique nature of these algorithms gives rise to a number
of major challenges for the would-be implementer. This pa-
per describes the first implementation of a mixed criticality
scheduling framework on a multicore system. We experimen-
tally evaluate design tradeoffs that arise when seeking to iso-
