- In this paper we describe the problem of achieving composability of independently developed real-time subsystems to be executed on a multicore platform.We evaluate existing work for achieving real-time performance on multicores and illustrate their lack with respect to composability. To better address composability we present a multi-resource server-based scheduling technique to provide predictable performance when composing multiple subsystems on a multicore platform. To achieve composability also on multicore platforms, we propose to add memory-bandwidth as an additional server resource. Tasks within our multi-resource servers are guaranteed both CPU- and memory-bandwidth; thus the performance of a server will become independent of resource usage by tasks in other servers. We are currently implementing multi-resource servers for the Enea’s OSE operating system for a P4080 8-core processor to be tested with software for a 3G-basestation.
