Libraries for Intel® 64 Architecture Targeting the Intel® Xeon Phi™ Coprocessor x100 Product Family

This topic only applies toIntel® 64 architecture targeting the Intel® Xeon Phi™ coprocessor x100 product family (formerly code name Knights Corner).

The C++ Class Libraries for Intel® 64 architecture targeting the Intel® Xeon Phi™ coprocessor x100 product family (formerly code name Knights Corner) enable Single Instruction, Multiple Data (SIMD) operations.

These libraries provide functionality very similar to the Intel® C++ Class Library for IA-32 and Intel®64 architectures, but for wider vectors. This functionality can be used in a code compiled for Intel® 64 architecture targeting the Intel® Xeon Phi™ coprocessor x100 product family (formerly code name Knights Corner).

For example, the Intel® C++ Class Library for IA-32 and Intel® 64 architecture provides the following classes:

Similarly, the library for Intel® 64 architecture targeting the Intel® Xeon Phi™ coprocessor x100 product family (formerly code name Knights Corner) provides the following classes (with similar functionality, but for wider vectors - 512bit instead of 128 or 256 bit):
