I just upgraded (side graded) to ICC V10.1.025
On my projects with OpenMP enabled the #pragma omp ... produce error messages in the ICC flavor of the project files. If I convert project back to MS C++ the project compiles as it should and produce parallel code. Yes, I checked the project to compile with OpenMP enabled and to produce parallel code.
Note, the particular project also included TBB. I don't know if that hoses anything in the ICC build.
