Calling oneMKL Functions from Multi-threaded Applications
This section summarizes typical usage models and available options for calling Intel® oneAPI Math Kernel Library functions from multi-threaded applications. These recommendations apply to any multi-threading environments: OpenMP*, Intel® Threading Building Blocks,POSIX* threads, and others.
Usage model: disable oneMKL internal threading for the whole application
When used:Intel® oneAPI Math Kernel Library internal threading interferes with application's own threading or may slow down the application.
Example: the application is threaded at top level, or the application runs concurrently with other applications.
Link statically or dynamically with the sequential library
Link with the Single Dynamic Library mkl_rt.dylib and select the sequential library using an environment variable or a function call:
‡ For details of the mentioned functions, see the Support Functions section of the Intel® oneAPI Math Kernel Library Developer Reference, available in the Intel Software Documentation Library.
