Default

Description

This option enables or disables vectorization.

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

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

Note

Using this option enables vectorization at default optimization levels 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).
