OpenMP*

internal threshold was exceeded

In very large, complex functions, loops preceded by OpenMP directives may not be threaded. Compiler may emit the warning remark: "An internal threshold was exceeded: loops may not be vectorized or parallelized. Try to reduce routine size."

    • OMP: Error #15: Initializing libguide.lib, but found libguide40.dll already initialized.

    Linker error generated when different parts of a program try to link both the static and dynamic versions of the OpenMP runtime. The solution is to expilcitly call out either a dynamic or static link.

    • Compiler 11.0 now defaults to linking dynamic OpenMP runtime

    Inviato da (non verificato) il

    In the 10.1 and earlier C++ and Fortran Windows compilers, the default for OpenMP programs was to link with the static OpenMP runtime libraries. The default has changed in the 11.0 compilers to link with the dynamic (using DLLs) OpenMP runtime.
