Introduction to Intel's valarray Implementation

The Intel® Compiler provides a high performance implementation of specialized one-dimensional valarray operations for the C++ standard STL valarray container.

The standard C++ valarray template consists of array/vector operations for high performance computing. These operations are designed to exploit high performance hardware features such as parallelism and achieve performance benefits.

Intel's valarray implementation uses the Intel® Integrated Performance Primitives (IPP), which is part of the product. Make sure you select IPP when you install the product.

The valarray implementation consists of a replacement header, <valarray>, that provides a specialized high performance implementation for the following operators and types:

Operator

Valarrays of Type

abs, acos, asin, atan, atan2, cos, cosh, exp, log, log10, pow, sin, sinh, sqrt, tan, tanh

float, double

addition, subtraction, division, multiplication

float, double

bitwise or, and, xor

(all unsigned) char, short, int

min, max, sum

signed or short/signed int, float, double
