Enhanced monitoring in the GRADE programming environment by using OMIS

To provide high-level graphical support for developing message passing prog rams, an integrated programming environment (GRADE) is being developed. GRA DE provides tools to construct, execute, debug, monitor and visualise messa ge-passing based parallel programs. The paper describes the integration of GRADE and an OMIS compliant monitor system. OMIS is a recent specification of a universal on-line monitoring interface for parallel and distributed pr ograms. The integration provides GRADE with a more flexible monitoring supp ort and makes possible the simultaneous usage of debugging and visualisatio n tools. The paper specifically addresses the requirements imposed by GRADE on the on-line event tracing mechanisms, as well as their implementation a nd performance. (C) 2000 Elsevier Science B.V.
