On Linux, using Eclipse, I am creating a C project that uses a combination of MPI and OpenMP.
I can get the project to build, but with some warning that I can ignore. This may not necessarily be an Intel, but a heads up.
When building the sample "Hello world" as OpenMP only, icc is used, and the build works without warnings.
When building the sample "Hello world" as MPI only, mpicc is used, and the build works without warnings.
When I build a mixed program, using mpicc, I receive warning relating to choice of options for enabling OpenMP. It appears that icc and mpicc are not using the same options.
The following is a successful build, but with warnings:
