Lecture 31d, Parallel Multiple precision PDE

Now we attack solving the PDE on multicore and multiprocessor
computer architectures using multiple precision arithmetic.
Many examples use GMP, Gnu Multiple Precision.

The basic concept is to use worker task to do the parallel
computation and a master control task, the main procedure,
to keep the workers synchronized. These examples, in several
languages, use the barrier method of synchronization.

Using pthreads and gmp to solve large systems of
simultaneous equations.
