Blender is a popular Open Source 3D modeling system. Recently the question was asked can one use the Flux cluster for 3D rendering. We were curious about this, and we wanted to support our students. Clusters like Flux though are normally built with scientific use in mind and we didn't know if what we had would support Blender. Turns out this was all easier than we thought.
GPU Rendering with CYCLES and CUDAWhat we found though is we wanted to use the CYCLES render, and not only that we wanted to run it on the FluxG GPU service. Why GPUs? Lets us use the current standard CYCLES benchmark file and compare GPU to CPU performance.
