Out of memory even though the assigned gpu is free

[jiangjiechu]

Notice that context buffer is created before gpu assignment:

OptixRenderer/src/optixRenderer/src/optixRenderer.cpp

Lines 514 to 525 in 84b48be

	unsigned scale = createContext(context, use_pbo, cameraInput.cameraType,
	cameraInput.width,
	cameraInput.height,
	mode,
	cameraInput.sampleNum,
	maxPathLength,
	rrBeginLength );
	if(gpuIds.size() != 0){
	std::cout<<"GPU Num: "<<gpuIds.size()<<std::endl;
	context -> setDevices(gpuIds.begin(), gpuIds.end() );
	}

This could induce serious memory harassment when there are other jobs running on a multi-GPU server. If any one gpu memory is used up, the program will throw out of memory exception and quit, despite that there are plenty of free devices.
The gpu should be set before the createBuffer() line in createContext():

OptixRenderer/src/optixRenderer/src/creator/createContext.cpp

Line 36 in 84b48be

Buffer outputBuffer = context -> createBuffer(RT_BUFFER_OUTPUT, RT_FORMAT_FLOAT3, bWidth, bHeight);

Sorry, I tried your solution, but it did not work? Any other advice?
