 * OpenMP v3.1, when released -- now supposed to be released this month (December 2010). Planned features: user-defined reductions (a major item), affinity, atomics extensions (support capture/write), and task scheduling items (`taskyield` construct, `final` clause) are to be expected. Cf. slides at the [[http://www.ccs.tsukuba.ac.jp/workshop/IWOMP2010/|IWOMP, the International Workshop for OpenMP]] ([[http://www.ccs.tsukuba.ac.jp/workshop/IWOMP2010/program.html|slides]] and [[http://www.ccs.tsukuba.ac.jp/workshop/IWOMP2010/tutorial.html|tutorials]]) in June 2010 and the [[http://www.springerlink.com/content/978-3-642-13216-2|OWOMP 2010 proceedings]].
