A Portable Run - Time Systemfor

This paper describes a parallel run-time system (RTS) that is used as part of the pC++ parallel programming language. The RTS has been implemented on a variety of scalable, MPP computers system diiers from other data-parallel RTS implementations; it is designed to support the operations from object-parallel programming that require remote member function execution and load and store operations on remote data. The implementation is designed to provide the thinnest possible layer atop the vendor-supplied machine interface. That thin veneer can then be used by other run-time layers to build machine independent class libraries, compiler back ends, and more 1 sophisticated run-time support. Some preliminary measurements of the RTS are given for the IBM SP2, SGI Power Challenge, and Cray T3D.
