Cluster OpenMP license now available on whatif

Hi everyone.  Cluster OpenMP was the first commercial version of OpenMP built on top of a distributed shared memory (DSM)  system supporting C, C++ and Fortran.  Now, we are making it available to the research community in the form of a free, downloadable single-user license on

I am the technical lead of the Cluster OpenMP project within Intel and have been a participant in the OpenMP language specification process for a number of years. 

I'll be blogging about Cluster OpenMP.  It's my first entry into the blogosphere, so it may take me some time to get my bearings, but I'll try to share some of the insights we've gained into the challenges and opportunities we've discovered in making Cluster OpenMP into an industrial-strength system. 

I hope you'll find what I have to say interesting, and I hope you have some time to give Cluster OpenMP a try.

Thanks for reading.

Thanks for your reply -- that's a shame, however.

Cluster OpenMP was a novel step forward in the direction of an important trend. Our team has had tremendous success using the MKL/OpenMP on multiprocessor Core i7 machines, and we were hoping to add even more threads in the near future via Cluster OpenMP. I really can't say enough good things about our multicore performance experience using the MKL for HPC, combined with the ability to incrementally parallelize code via OpenMP.

Without divulging any "trade secrets", is Intel pursuing a solution that would allow large numbers of threads in the future (say >256)?

Hello Greg,

We're sorry, Cluster OpenMP is no longer available, and there are no plans to offer it in the future.

Best regards,

Can you comment on the future of Cluster OpenMP? I ask because it doesn't seem to be currently available on WhatIf.

I received this in an e-mail:

* For C luster OpenMP* for Intel® C++ Compiler for Linux*, you must download the additional license required to activate the Cluster OpenMP* features of the Compiler.

How do I do this? Where is it at?
