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 (Intel® IPP), which is part of the product. 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:
