Abstract
A runtime system provides a parallel language compiler with an interface to the low-level facilities required to support interaction between concurrently executing program components. Nexus is a portable runtime system for taskparallel programming languages. Distinguishing features of Nexus include its support for multiple threads of control, dynamic processor acquisition, dynamic address space creation, a global memory model via interprocessor references, and asynchronous events. In addition, it supports heterogeneityat multiple levels, allowing a single computation to utilize di#erent programming languages, executables, processors, and network protocols. Nexus is currently being used as a compiler target for two task-parallel languages: Fortran M and Compositional C++ . In this paper, we present the Nexus design, outline techniques used to implement Nexus on parallel computers, showhowitis used in compilers, and compare its performance with that of another runtime system...
