Cluster OpenMP - more information?

[tobias-burnus]

Hello,



on the compiler product pages of icc 9.1 and ifort 9.1 I found that they now support to use (slightly modified?) OpenMP directives to compile/run a program on a distributed-memory computer cluster.



Which is termed "Cluster OpenMP".



Unfortunally, the web is rather oblique on the details.



One finds a whitepaper:

http://cache-www.intel.com/cd/00/00/28/58/285865_285865.pdf



A conference of a high-performance computation center:

http://www.hlrs.de/news-events/events/2006/openmpworkshop/



And FAQ:

http://www.intel.com/support/performancetools/sb/cs-022403.htm



But no details.



On the ifort 9.1/Linux pages one finds:

"Cluster OpenMP enables a slightly modified OpenMP program to run on a Linux 64-bit Intel-based cluster."



What I really miss is:

(a) What are the modification needed?

(b) What are the pre-requirements/setups needed to use Cluster OpenMP?

This whitepaper describes Cluster OpenMP in general. I've attached the User Manual to this reply.

I know that the system requirements include an Intel EM64T-based system, but I can't put my hands on the other system requirements right now. When I find them I'll let you know.

In addition to Intel EM64T processor, Cluster OpenMP supports Intel Itanium 2 processors. Attached are the Cluster OpenMP release notes - same for both C++ and Fortran. The release notes explain the supported Linux distributions, cluster requirements, etc.

Let us know if you have additional questions, thanks,
