4.6.1 Shared-memory parallelization

Most CL implementations have some threading capabilities which allow to use the multi-core processors efficiently that can be found in most of the current computers. Unfortunately, this has not yet been standardized (the ANSI CL standard is from 1994!), so that each CL implementation provides an own set of functions for making this possible. On the other hand, the bordeaux-threads library provides a unified interface to these capabilities, and the lparallel library even provides a higher level of abstraction, because it allows to allocate a pool of workers which can work on sequences using parallel map and parallel reduce operations.

FEMLISP uses both of these libraries for providing an interface which is slightly more complicated than pmap/preduce, but can be applied inside every iterative form.
