Types of Loop Vectorized

For integer loops, the Itanium-based MMX(TM) technology and 128-bit Streaming SIMD Extensions (SSE) provide SIMD instructions for most arithmetic and logical operators on 32-bit, 16-bit, and 8-bit integer data types.

Note  
Vectorization may proceed if the final precision of integer wrap-around arithmetic will be preserved. A 32-bit shift-right operator, for instance, is not vectorized if the final stored value is a 16-bit integer.

Note
Because the MMX(TM) and SSE instruction sets are not fully orthogonal (byte shifts, for instance, are not supported), not all integer operations can actually be vectorized.

For loops that operate on 32-bit single-precision and 64-bit double-precision floating-point numbers, SSE provides SIMD instructions for the arithmetic operators '+', '-', '*', and '/'. In addition, SSE provides SIMD instructions for the binary MIN and MAX and unary SQRT operators. SIMD versions of several other mathematical operators (like the trigonometric functions SIN, COS, TAN) are supported in software in a vector mathematical runtime library that is provided with the Intel® Fortran Compiler.
