Is OpenMP a standard, a specification?

Postby Stephane » Sun Feb 14, 2010 11:09 am


I am wondering if OpenMP is a specification or a standard, and in the second case, is it ISO, ANSI? I couldn't find any clear answer to that on the web.

And, well, you know, I have a boss who likes standards... :D

Thank you,

It's a specification whose support is so widespread that it's pretty much a de facto standard (like MPI).

A partial list (off the top of my head, I'd add the OpenUH and Cray compilers) that support OpenMP
is here:

Not every compiler that supports OpenMP supports the latest version of the specification (3.0), but at least
the GCC, Intel, PGI, Sun Studio, IBM, and Cray compilers do.
