Detailed Description

A DeviceConstraint restricts the type of processing device, which HyPE may choose to process an operator.

This is especially important if an algorithms does not support a certain data type on a certain processing device (e.g., no filter operations on an array of strings on the GPU). On default construction, no constraint is defined.

Constructor & Destructor Documentation

hype::core::DeviceConstraint::DeviceConstraint	(	DeviceTypeConstraint	dev_constr = ANY_DEVICE,
		ProcessingDeviceMemoryID	pd_mem_constr = PD_Memory_0
	)

constructs an DeviceConstraint object by assigning necessary informations to all fields of the object

Parameters:

dev_constr	a device type constraint (e.g., CPU_ONLY or ANY_DEVICE for now restriction)
pd_mem_constr	memory id, where the data should be stored when processed (experimental)
