Detailed Description

optix and cuda context for a single, specific GPU

Member Typedef Documentation

SP

typedef std::shared_ptr<DeviceContext> owl::DeviceContext::SP

Constructor & Destructor Documentation

DeviceContext()

owl::DeviceContext::DeviceContext	(	Context *	parent,
		int	owlID,
		int	cudaID
	)

create a new device context with given context object, using given GPU "cudaID", and serving the rols at the "owlID"th GPU in that context

Member Function Documentation

buildHitGroupPrograms()

void owl::DeviceContext::buildHitGroupPrograms

(

)

buildMissPrograms()

void owl::DeviceContext::buildMissPrograms

(

)

build all optix progrmas for miss program types

buildPipeline()

void owl::DeviceContext::buildPipeline

(

)

buildPrograms()

void owl::DeviceContext::buildPrograms

(

)

buildRayGenPrograms()

void owl::DeviceContext::buildRayGenPrograms

(

)

configurePipelineOptions()

void owl::DeviceContext::configurePipelineOptions

(

)

configures the optixPipeline link options and compile options, based on what values (motion blur on/off, multi-level instnacing, etc) are set in the context

getCudaDeviceID()

int owl::DeviceContext::getCudaDeviceID

(

)

const

helper function - return cuda device ID of this device

getDeviceName()

std::string owl::DeviceContext::getDeviceName

(

)

const

helper function - return cuda name of this device

return CUDA's name string for given device

getStream()

CUstream owl::DeviceContext::getStream ( ) const

inline

return the optix default stream for this device. launch params may use their own stream

Member Data Documentation

allActivePrograms

std::vector<OptixProgramGroup> owl::DeviceContext::allActivePrograms

collects all compiled programs during 'buildPrograms', such that all active progs can then be passed to optix durign pipeline creation

cudaContext

CUcontext owl::DeviceContext::cudaContext = nullptr

cudaDeviceID

const int owl::DeviceContext::cudaDeviceID

ID

const int owl::DeviceContext::ID

linear ID (0,1,2,...) of how we number devices (i.e., 'first' device is always device 0, no matter if it runs on another physical/cuda device)

moduleCompileOptions

OptixModuleCompileOptions owl::DeviceContext::moduleCompileOptions = {}

optixContext

OptixDeviceContext owl::DeviceContext::optixContext = nullptr

parent

Context* const owl::DeviceContext::parent

the owl context that this device is in

pipeline

OptixPipeline owl::DeviceContext::pipeline = nullptr

pipelineCompileOptions

OptixPipelineCompileOptions owl::DeviceContext::pipelineCompileOptions = {}

pipelineLinkOptions

OptixPipelineLinkOptions owl::DeviceContext::pipelineLinkOptions = {}

sbt

SBT owl::DeviceContext::sbt = {}

stream

CUstream owl::DeviceContext::stream = nullptr
