»More Experiments from Christian Terboven on Tasking in 3.0
Christian Terboven at the University of Aachen continues his experiments with OpenMP 3.0 tasking:
»More on Tasking in OpenMP 3.0
We already played a lot with Tasking and are looking into how well it can be applied to *real* applications. In the “Introduction to Parallel Programming” lecture and also in the discussions following after some of my recent talks I noticed a strong interest in this new paradigm and I really hope that people will like it!

»OpenMP 3.0 in Sun Studio Express 7.08 Compilers
Sun Studio Express July 2008 released today implements some of the new OpenMP 3.0 features in their C, C++, and Fortran compilers and tools.
Runs on Solaris, OpenSolaris, and Linux, on SPARC and x86/x64 platforms, and it’s a free download from the Sun Studio portal.
Details on what OpenMP 3.0 features are implemented in this “beta” release is on the Sun Studio Wiki.
»IWOMP 2009 Announced
The 5th International Workshop on OpenMP: Evolving OpenMP in an Age of Extreme Parallelism - will take place in Dresden (Germany) from the 3rd June through the 5th June 2009.
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.

»Christian’s First Experiments with Tasking in OpenMP 3.0
From Christian Terboven’s blog:
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.
