This happens because the default RTX dynamic memory size it too small. You can increase it by adding “OS_DYNAMIC_MEM_SIZE=16384” to the preprocessor definitions: Note how this increases the size of the os_mem variable by 12KB: Now you can run the program and see the timing diagram for...
the new memory system to improve the speed and resolution in gaming, NVIDIA NVLink providing higher bandwidth and improved scalability, hardware support for USB Type-C and its benefits and new technologies improving VR applications including Variable Rate Shading, Multi-View Rendering...
In our implementation, the ray-tracing process is a synchronized flow between the ray-tracing shaders, which execute on the XVE, and scene traversal, which executes in the RTU. To initiate ray tracing, a ray-generation shader running on the XVE writes ray data to memory, and sends a SI...
in addition to the actual AS. In the case of the// top-level AS, the instance descriptors also need to be stored in GPU// memory. This call outputs the memory requirements for each (scratch,// results, instance descriptors) so that the application can allocate the// corresponding memory...
NVIDIA today announced its first Turing architecture-based GPUs, revolutionizing the work of 50 million designers and artists by enabling them to render photorealistic scenes in real time, add new AI-based capabilities to their workflows, and enjoy fluid
为了存到off-chip memory,法线压缩为一个float,outgoing radiance精度为half,一个蓄水池需要48B。双缓冲1080p大概500MBpf,带宽大概600MBpf。 只在1/4的pixel上采样长路径,其余单bounce,为了线程的coherency,分块轮盘赌选择是否采样长路径。 clamp M值防止M过大时蓄水池卡死,时间蓄水池M最大为30,空间蓄水池最大...
