If you were wondering what’s up with last week’s ‘Introducing Lunchbox’ post: There wasn’t one since I’ve been to the Eurographics Symposium on Parallel Graphics and Visualization to present our paper “Parallel Rendering on Hybrid Multi-GPU Clusters”. This week I’m attending Eurographics, but I’ll try to post the fourth article in the Lunchbox series by Friday.
Our paper presented a collection and evaluation of optimizations for medium-sized GPU clusters which use Multi-GPU NUMA nodes. This type of architecture is quite important, since it provides a cost-effective configuration for parallel rendering, since the host and network infrastructure cost is amortized over multiple GPUs. During this paper we found a few surprising insights (<cough>glFinish</cough>) on what optimizations are actually important.
Enough talk: The most important parts are summarized in our presention. Enjoy!
