For cost-effective realization of sizable real-time distributed computing application systems, significant advances in resource allocation are in critical needs. An advanced practical scheme for high-level programming of real-time distributed computing software such as the TMO (Time-triggered Message-triggered Object) scheme introduces the potential for realizing new improved resource allocation approaches. The main reason is because it provides information-rich intuitively appealing timing specifications. However, to properly exploit the potential, a number of issues need to be resolved via extensive research involving both analytical and experimental efforts.??A hierarchical resource allocation scheme that becomes enabled by use of the TMO programming model is discussed along with the remaining research issues.
