Performance Guide Options Selector dialog box

The Options Selector dialog box is part of the Performance Guide. To access the Performance Guide, click Tools > Intel Compiler > Start Performance Guide.

Click one or more of the following to select the characteristics that best describe your application.

Application can accept better floating point performance at a slight cost in accuracy or consistency: The Performance Guide will select the /fp:fast option.

Optimize for the processor architecture that you are running on: The compiler will generate instructions for the processor performing the compilation. The Performance Guide will select the /QxHost option. This is one of many compiler options available for architecture selection. A different compiler option may be more appropriate, depending on where your application will be deployed.

Enable the auto-parallelizer to generate multi-threaded code for loops that can be safely executed in parallel: The Performance Guide will select the /Qparallel option.

Application has loops that do many floating-point calculations or process large data sets: The Performance Guide will select the /O3 option.

Optimization Notice

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.
