RTT achieves outstanding rendering performance with Mellanox InfiniBand

Rapid Data Stream Provides Real-time Visualisation with Wings

Munich, November 30, 2009 – High-end visualisation in real time places great demands on the interaction between software and hardware. The massive volumes of data involved can only be displayed fluidly and in a convincing manner if all the components are perfectly attuned to one another. In this respect, the quality of the network connection is of central importance for cluster installations. In a series of trials carried out at its development laboratory in Munich, Realtime Technology (RTT) AG tested the rendering process of its industry-leading visualisation software RTT DeltaGen with Mellanox world-leading InfiniBand end-to-end connectivity. The results were impressive to say the least.

In order to test the performance of the data transfer with Mellanox solutions, RTT Scale (the scalability module of RTT DeltaGen) was used to integrate a cluster of five computers (with two high-performance graphics processors each) via Mellanox InfiniBand. Sophisticated, real-time visualisations were then rendered, a process which involved an enormous volume of data due to the physically correct display of textures, refractions, reflections and shadow effects required. The fact that OpenGL, Global Illumination and ray tracing were involved here meant that all three of the software’s rendering processes were utilised.

Experts from RTT examined the quality of the real-time display. They paid particular attention to continuous colour gradients, smooth lighting effects and seamless transitions between animations. – And the result? The network connection using Mellanox InfiniBand passed with flying colours. It interacted extremely well with RTT Scale and the hardware constellation used in the test setup. With transfer rates of up to 8 gigabits per second, the system performed superbly with all three rendering methods and produced excellent real-time visualisation results.

Christoph Karrasch, co-founder and board member of RTT, was more than satisfied with the outcome: “We were impressed by the performance of the system we tested. On the basis of our test results we would have no hesitation in recommending the InfiniBand connectivity from Mellanox for high-end real-time visualisation with RTT DeltaGen.” In addition to the exceptionally high bandwidth and the short latency periods, RTT’s testers put the good performance of the InfiniBand network down to the efficient load balancing. Thanks to the optimal distribution of data packages, it was possible to get very close to achieving perfect loading among the graphics processors.

Gilad Shainer, Director of HPC and Technical Marketing at Mellanox Technologies, is delighted about the recommendation from RTT. “The results of RTT’s trials are further confirmation of the outstanding functionality of our highest-bandwidth, lowest latency InfiniBand end-to-end solutions. The real-time visualisation allowed us to demonstrate our capabilities to a sector that relies on being able to transfer and distribute large volumes of data rapidly and reliably.”
