GRADE-OMIS

Distributed On-line Monitoring and Debugging in the Graphical Programming Environment GRADE

(BMBF-WTZ Project UNG-053-96)

Project Goal

The GRADE-OMIS project aims at bringing together the graphical parallel programming environment GRADE developed at the MTA SZTAKI research institute (formerly KFKI) with the OMIS compliant monitoring system and the deterministic execution controller developed at LRR-TUM.

GRADE allows to graphically specify the parallel parts of an application, i.e. those pieces that use communication, in a graphical language called GRAPNEL. Sequential subroutines can be called from within that specification. A built-in compiler then translates the graphics to a C program with calls to the GRAPNEL library, which uses PVM for message passing and process control. A distributed debugger integrated with the graphics editor allows to view the parallel execution of the program at the level of the graphical specification.

Combining the GRADE enviroment with an OMIS compliant monitoring system offers greater flexibility for that environment, better portability (a port to MPI is planned), and will allow to use codex in combination with the GRADE debugger to ensure deterministic execution. On the other hand, the adaption of the OMIS compliant monitoring system is a test case for the flexibility and adaptability of the concepts incorporated into OMIS.

The project is funded by the German and Hungarian state, respectively, in the framework of the WTZ programme (scientific and technical collaboration between Germany and Eastern Europe).
