What You Need to Know Before You Begin Using the Intel® oneAPI Math Kernel Library
Target platform
| Identify the architecture of your target machine:
Reason: Because
Architecture SupportIntel® oneAPI Math Kernel Library ), you should provide proper paths on your link lines (see Linking Examples). To configure your development environment for the use with
Intel® oneAPI Math Kernel Library |
Mathematical problem
| Identify all
Intel® oneAPI Math Kernel Library
Reason: The function domain you intend to use narrows the search in the
Intel® oneAPI Math Kernel Library Intel® oneAPI Math Kernel Library |
Programming language
| Intel® oneAPI Math Kernel Library Reason: Intel® oneAPI Math Kernel Library For a list of language-specific interface libraries and modules and an example how to generate them, see also
Using Language-Specific Interfaces with Intel® oneAPI Math Kernel Library.
|
Range of integer data
| If your system is based on the Intel 64
architecture, identify whether your application performs calculations with large data arrays (of more than 231 -1 elements).
Reason: To operate on large data arrays, you need to select the ILP64 interface, where integers are 64-bit; otherwise, use the default, LP64, interface, where integers are 32-bit (see
Using the ILP64 Interface vs).
|
Threading model
| Identify whether and how your application is threaded:
Reason: The compiler you use to thread your application determines which threading library you should link with your application. For applications threaded with a third-party compiler you may need to use
Intel® oneAPI Math Kernel Library |
Number of threads
| If your application uses an OpenMP* threading run-time library, determine the number of threads you want
Intel® oneAPI Math Kernel Library Reason: By default, the OpenMP* run-time library sets the number of threads for
Intel® oneAPI Math Kernel Library |
Linking model
| Decide which linking model is appropriate for linking your application with
Intel® oneAPI Math Kernel Library
Reason: The link
libraries for static and dynamic linking are different. For the list of link libraries for static and dynamic models, linking examples, and other relevant topics, like how to save disk space by creating a custom dynamic library, see
Linking Your Application with the Intel® oneAPI Math Kernel Library.
|
MPI used
| Decide what MPI you will use with the
Intel® oneAPI Math Kernel Library Reason: To link your application with ScaLAPACK and/or Cluster FFT, the libraries corresponding to your particular MPI should be listed on the link line (see
Working with the Intel® oneAPI Math Kernel Library Cluster Software).
