[ Marks the beginning of a bracket expression. will be an Atomic type read and write operations are minimized from a set of instructions to a single CPU instruction. E.g: std::atomiccounter; And provides basic numeric member functions for operations. In principle, each thread can correspond to a cluster node, and communication between threads is almost equivalent to communication between cluster nodes.

Managed memory is accessible to both the CPU and GPU using a single pointer. The key is that the system automatically migrates data allocated in Unified Memory between and GPU, bridging the CPU-GPU divide.
