| Mitsuba 3 is an open-source research renderer capable of high-performance local parallelization based on just-in-time (JIT) compilation of computation kernels for many-core CPUs (via LLVM) and GPUs (via CUDA/OptiX). However, its performance is always limited to only one machine and CPU/GPU, as Mitsuba 3 does not support execution on multiple machines or execution on CPU and GPU simultaneously. This limitation is common in research renderers and the goal of this thesis is to find a solution.
The student should implement a framework to allow distributed rendering for Mitsuba 3, and optionally other similar renderers, allowing it to run both on cloud-based providers of compute nodes and on local servers, for example within a university or company computational network. The implementation should include: - A combined run-time load balancing: - 1) Taking into account the computational performance, because the nodes may have different hardware (combinations of CPU and GPU of different speeds). - 2) Taking into account local image quality metrics, because different regions of the renderer image may vary wildly in their complexity and variance (noise levels), so some regions may converge with a lower number of samples than other regions, and it would be wasteful to continue rendering such regions further. - Real-time preview of the rendered scene, such that the user can see the progress and decide to manually stop the rendering. - Support for differentiable (inverse) rendering, mainly the distributed framework should be compatible with inverse rendering optimization pipelines. - Python-based API for ease of use and, if possible, integration with the Python API of Mitsuba 3. - Ready-to-use Docker containers that can be easily deployed within a local network and within a chosen cloud infrastructure. |
