How to check the version of OpenMP on Linux

Question

I wonder how to check the version of OpenMP on a Linux remote machine?

I don\'t know where it is installed either.

Answer 1

You need to check your gcc version using

gcc --version

and then see the (incomplete) table below (whose info is gathered from this Wiki article and from this webpage from the OpenMP official website):

| gcc version | OpenMP version |    Languages    | Offloading |
|-------------|----------------|-----------------|------------|
|    4.2.0    |       2.5      |        C        |            |
|    4.4.0    |       3.0      |        C        |            |
|    4.7.0    |       3.1      |        C        |            |
|    4.9.0    |       4.0      |      C, C++     |            |
|    4.9.1    |       4.0      | C, C++, Fortran |            |
|      5      |                |                 |     Yes    |
|     6.1     |       4.5      |      C, C++     |            |

The blank entries are there because I didn't find the corresponding info.
