Improving Performance for Small Size Problems
- Compile your C or Fortran code with the preprocessor macro depending on whether a threaded or sequential mode ofis required by supplying the compiler option as explained below:Intel® MKLModeIntel® MKLMacroCompiler OptionThreadedMKL_DIRECT_CALL-DMKL_DIRECT_CALLSequentialMKL_DIRECT_CALL_SEQ-DMKL_DIRECT_CALL_SEQ
- For Fortran applications:
- Enable preprocessor by using the-fppoption for Intel® Fortran Compiler and-Mpreprocessoption for PGI* compilers.
- Include theFortran include fileIntel® MKLmkl_direct_call.fi.
Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
