Distributed Maple: Parallel Computer Algebra in Networked Environments
=abstract=
We describe the design and use of Distributed Maple, an environment for
executing parallel computer algebra programs on multiprocessors and
heterogeneous clusters. The system embeds kernels of the computer 
algebra system Maple as computational engines into a networked 
coordination layer implemented in the programming language Java.  On the 
basis of a comparatively high-level programming model, one may write 
parallel Maple programs that show good speedups in medium-scaled 
environments. We report on the use of the system for the parallelization 
of various functions of the algebraic geometry library CASA and 
demonstrate how design decisions affect the dynamic behavior and 
performance of a parallel application.  Numerous experimental results 
allow to compare Distributed Maple with other systems for parallel 
computer algebra.
