P_GRADE

P-GRADE [MTA SZTAKI dozsa,kacsuk,lovas,podhorszki,drotos] is a grid application development environment. It uses Globus, Condor-G and MPICH-G2 as grid-aware middleware to conduct computations. To provide Grid programming interface with support for workflow and orchestration P-GRADE uses GRAPNEL language which allows a programmer to set a workflow of objects/library calls. Special tool may be used to generate MPI code from a GRAPNEL program.

Legacy application support: C,C++,Fortran,MPI,PVM.
