Detailed Description

a buffer that uses CUDA 'managed' memory. only makes sense for copyable data types. Make sure to read up on how managed mem works

Member Typedef Documentation

Constructor & Destructor Documentation

ManagedMemoryBuffer()

owl::ManagedMemoryBuffer::ManagedMemoryBuffer	(	Context *const	context,
		OWLDataType	type
	)

Member Function Documentation

resize()

void owl::ManagedMemoryBuffer::resize ( size_t  newElementCount )

overridevirtual

resize buffer to new num elements

Implements owl::Buffer.

toString()

std::string owl::ManagedMemoryBuffer::toString ( ) const

overridevirtual

pretty-printer, for debugging

Reimplemented from owl::Buffer.

upload() [1/2]

void owl::ManagedMemoryBuffer::upload ( const int  deviceID, const void *  hostPtr  )

overridevirtual

upload data from host, to only given device ID

Implements owl::Buffer.

upload() [2/2]

void owl::ManagedMemoryBuffer::upload ( const void *  hostPtr )

overridevirtual

upload data from host, using as many bytes as required by elemnetCount and dataSize

Implements owl::Buffer.

Member Data Documentation

cudaManagedMem

void* owl::ManagedMemoryBuffer::cudaManagedMem { 0 }

pointer to the (shared) cuda managed mem - this gets alloced once and is valid on both host and devices
