In this poster we present the recent advances in Equalizer, a framework for scalable parallel rendering based on OpenGL, which provides an application programming interface (API) to develop scalable graphics applications for a wide range of systems ranging from large distributed visualization clusters and multi-processor multi-GPU graphics systems to single-GPU desktop machines. Recent advances include optimizations for visualization clusters using multi-GPU NUMA nodes, tile and subpixel decompositions, automatic configuration on multi-GPU machines and scalable visualization clusters, as well as novel features for Virtual Reality, most notably support for dynamic focus distance.
