Detailed Description

Atomic functions.

This header file defines prototypes for the following atomic functions:

• exchange
• compare and exchange
• add

Supported types include:

• signed and unsigned 4 and 8 byte integers
• float
• double

They are implemented through GCC compatible intrinsics, OpenMP directives and native CUDA intrinsics.

Including this header file requires one of the following compilers:

• NVCC (for CUDA device code only)
• GCC (for host code only)
• Intel (for host code only)
• A compiler that supports OpenMP 3.1 (for host code only)
