CUDA MEMORY

Dear authors:

It's my great honor to read your paper and learn your program.

When I run the render, I got a error, as shown below:

I have no name!@c398a3ecda9c:/virtualobjectinsertion$ ../OptixRenderer-master/build/bin/optixRenderer -f scene.xml -o scene.rgbe -m 0 --gpuIds 5 7 Input file name: /virtualobjectinsertion/scene.xml Output file name: /virtualobjectinsertion/scene.rgbe Material num: 2 Shape num: 2 Vertex num: 4802 Camera Parameters: Camera Field of View: 63.4149 Width: 640 Height: 414 FovAxis: x Target: 0 0 1 Origin: 0 0 0 Up: 0 1 0 Sample Count: 1024 Sampler: adaptive Sampler Count: 1024 Environmental map:/virtualobjectinsertion/demo3/env.hdr Environmental scale: 1 No point light source. terminate called after throwing an instance of 'optix::Exception' what(): Memory allocation failed (Details: Function "RTresult _rtBufferCreate(RTcontext, unsigned int, RTbuffer_api**)" caught exception: Encountered a CUDA error: cudaDriver().CuDevicePrimaryCtxRetain( &context, dev.get() ) returned (2): Out of memory ================================================================================ Backtrace: (0) () +0x711f17 (1) () +0x7102cb (2) () +0x563a39 (3) () +0x31c7e0 (4) () +0x325273 (5) () +0x1b11e1 (6) rtBufferCreate() +0x2a6 (7) optix::ContextObj::createBuffer(unsigned int, RTformat, unsigned long, unsigned long) +0x55 (8) createContext(optix::Handleoptix::ContextObj&, bool, std::__cxx11::basic_string<char, std::char_traits, std::allocator >, unsigned int, unsigned int, unsigned int, unsigned int, unsigned int, unsigned int) +0x203 (9) main() +0x2549 (10) __libc_start_main() +0xe7 (11) _start() +0x2a ================================================================================ ) Aborted

I guess the reason is about hardware, and my gpus are Quadro TRX 6000. I used the command with [--gpuIds 5 7], utlizing 2 gpus.

I want to know your GPU environment, and how much cuda memory is enough?

Also, the error logs says "No point light source.", I don't know whether it is a matter!

Please help me or anyone who knows the reseaons please tell me!

Many thanks!

Best regards!
