We are developing a pattern language to guide the programmer
through the entire process of developing a parallel application
program.  The pattern language includes patterns that help
find the concurrency in the problem, patterns that help find
the appropriate algorithm structure to exploit the concurrency
in parallel execution, and patterns describing lower-level
implementation issues.  The current version of the pattern language
can be seen at http://www.cise.ufl.edu/research/ParallelPatterns.

In this paper, we outline the overall structure of the pattern
language and present two groups of selected patterns, one group
chosen from the subset of patterns that represent different
strategies for exploiting concurrency once it has been identified
and one group chosen from the subset of patterns that represent
commonly-used computational and data structures.
