SYMGRID-PAR ============= Abdallah Al Zain Abstract The SymGrid-Par is a middleware, which orchestrates computational algebra components into a parallel application. SymGrid-Par components communicate using OpenMath, an XML-based data description format, designed specifically to represent computational mathematical objects. SymGrid-Par uses parallel Haskell implementation, Eden. It exploits the capabilities of the parallel Haskell implementation by layering a simple application programming interface (API) over them comprising two generic interfaces: the CAG interface links computational algebra systems to the parallel Haskell; and the GCA interface conversely links the parallel Haskell to these systems. This lecture presents SymGrid-Par and how to use it, also it demonstrates the practicality of using this system in computational algebra.
