[erlang-questions] How to Name Concurrency Patterns

There's a reasonable collection of resources here for parallel patterns:


POSA2 probably has the most accessible and well known concurrency patterns:


POSA4 has a reasonable set for distributed systems, at least the well known


Another good one is The Art of Multiprocessor Programming:


Naming sucks though. An audience with Java/JVM experience may know of
the LMAX Disruptor and maybe the coalescing ring buffer but that level of
detail may be too audience specific. Or, being general, these are just queue

Forgetting the patterns for a minute. Making sure Amdahl, Little and
Moore's laws
are known and understood would be a good start. Possibly with explaining
being concurrent, parallel or simultaneous means. Good foundations
of the terminology ultimately chosen...
