TOP2 - Partial Parallelization for Paragon

Parallelization of sequential programs for distributed memory machines generally involves non-local modifications to the program code. Thus, for large applications, it may be very time-consuming even to experiment with different parallelization strategies for only relatively small computational kernels. TOP2 is a tool suite developed at KFA/ZAM supporting partial parallelization of large applications for distributed memory multiprocessors, especially Intel iPSC/860 and Intel Paragon. It allows the user to experiment with different parallelization strategies on the basis of individual subroutines and to incrementally parallelize his application
