Detailed Description

Device memory domain.

• Secondary memory space attached to a compute accelerator
• Requires explicit data transfer from host domain
  
• Allocation strategies may vary by device capabilities
• Memory operations are asynchronous by default
• Each instance manages a single logical device

Warning

Device memory management is highly likely to change as the backend evolves.

Constructor & Destructor Documentation

Device()

tannic::Device::Device	(	int	id = 0,
		bool	blocking = false
	)

Constructs a device memory environment.

Parameters

id	Target device identifier (0-based)
blocking	Enable synchronous operation mode
