Default

-simd
or/Qsimd

The SIMD vectorization feature is enabled.

Description

This option enables or disables the SIMD vectorization feature of the compiler.

To disable the SIMD transformations for vectorization, specify -no-simd (Linux and Mac OS X) or /Qsimd- (Windows).

To disable vectorization, specify options -no-vec (Linux and Mac OS X) or /Qvec- (Windows).

Note iconNote

The SIMD vectorization feature is available for both Intel® microprocessors and non-Intel microprocessors. Vectorization may call library routines that can result in additional performance gain on Intel microprocessors than on non-Intel microprocessors. The vectorization can also be affected by certain options, such as /arch or /Qx (Windows) or -m or -x (Linux and Mac OS X).
