Description |
---|---|---|
vendor |
INTEGER*4 |
Specifies the implementation of the message-passing interface (MPI) to use: Possible values:
|
custom_library_namevendor |
CHARACTER* |
The filename (without a directory name) of the custom BLACS dynamic library to use. This library must be located in the directory with your application executable or with Intel® oneAPI Math Kernel Library (oneMKL) dynamic libraries. Can beNULL or an empty string. |
Description
Call this function to set the MPI implementation to be used by Intel® oneAPI Math Kernel Library (oneMKL) on Windows* OS when dynamic Intel® oneAPI Math Kernel Library (oneMKL) libraries are used. For all other configurations, the function returns an error indicating that you cannot set the MPI implementation. You can specify your own prebuilt dynamic BLACS library for a custom MPI by settingvendor to MKL_BLACS_CUSTOM and optionally passing the name of the custom BLACS dynamic library. If the custom_library_path parameter is NULLor an empty string, Intel® oneAPI Math Kernel Library (oneMKL) uses the default platform-specific library name:mkl_blacs_custom_lp64.dll or mkl_blacs_custom_ilp64.dll, depending on whether the BLACS interface linked against your application is LP64 or ILP64.
