Member Function Documentation

broadcast()

void MaterialHandler::broadcast	(	int	root = 0,
		bool	fromDevice = false,
		bool	toDevice = true
	)

Broadcast material instances to all MPI processes from a root

Parameters

root	root to broadcast from (default: MPI process 0)
fromDevice	flag whether start from device
toDevice	flag whether start from device

Definition at line 159 of file material_handler.cpp.

Here is the call graph for this function:

communicate()

void MaterialHandler::communicate	(	int	from,
		int	to,
		bool	fromDevice = false,
		bool	toDevice = true
	)

Communicate material instances between MPI processes and in addition from and/or to the device(s).

Warning

it is not possible to send it from device to device via CUDA-aware MPI, since serialize functionality not usable on device

Parameters

from	MPI process source
to	MPI process target
fromDevice	flag whether start from device
toDevice	flag whether start from device

Definition at line 136 of file material_handler.cpp.

Here is the call graph for this function:

copy()

void MaterialHandler::copy	(	To::Target	target,
		integer	index = -1
	)

Copy material instance(s) from host to device or vice-versa.

Parameters

target	target: host or device
index	material instance index to be copied, if -1 copy all instances
