The workshop will be hosted by the Center for Information Services & High Performance Computing (ZIH) at the Dresden University of Technology.

The International Workshop on OpenMP is an annual series of international workshops dedicated to the promotion and advancement of all aspects focusing on parallel programming with OpenMP. The workshop serves as a forum to present the latest research ideas and results related to this shared memory programming model.

More information is at the IWOMP website, »http://www.iwomp.org/

The technical program will be announced on the IWOMP website (and here) in March, 2009.

OpenMP 3.0 is out, maybe a bit later than we hoped for, but I think that we got a solid standard document. At IWOMP 2008 a couple of weeks ago, there was an OpenMP tutorial which included a talk by Alex Duran (from UPC in Barcelona, Spain) on what is new in OpenMP 3.0 - which is really worth a look! My talk was on some OpenMP application experiences, including a case study on Windows, and I really think that many of our codes can profit from Tasks. Motivated by Alex’ talk I tried the updated Nanos compiler and prepared a couple of examples for my lectures on Parallel Programming in Maastricht and Aachen. In this post I am walking through the simplest one: Computing the Fibonacci number in parallel.

The 3.0 draft specifications were out for public review from October thru January. The final 3.0 specs is now available. It corrects a number of typos, clarifies some issues raised during the review period, and contains completed appendicies and lists of examples and implementation-defined features.
