Dave Patterson, et al., U.C., Berkely

A web page from Dec. 18, 2006: The Landscape of Parallel Computing Research: A View from Berkeley - Introduces this pdf.

My summary of this paper (they call it white):
• Goal = make it easy to write programs (that execute efficiently on highly parallel systems).
• 1000s of cores per chip.
• For benchmarking, use Dwarfs (a dwarf is a basic class of patterns of computation and communication, a primary type of computation); this team has defined 13 dwarfs currently. For example, MapReduce is a dwarf, Spectral Methods (a type of DSP that includes FFT) is another.
• Use Autotuners to select the most effective implementation of a library, of a dwarf or other pattern, at development or deploy time.
• Programming models to be more human-centric (to help developers with concurrency issues).
• Programming models to be independent of the number of processors where an application is deployed.
• Systems to include performance and energy counters adapted to multicore and for use by developers.

The blog - very useful, I recommend it.

The wiki. I don't know how complete this section is but it is useful start: Parallel Programming Model Watch

The glossary is also useful and necessary to read this wiki.

A discussion on Slashdot. Entries show that many if not most developers have a weak grasp of the issues. There's a lot of work to be done for multicores to be effectively used.
