    Lightbulb 2D runtimes and GPU cards

    Run-times for 2D models is a common talking point. Significant reductions in runtime can be achived when 2D models are processed on an NVIDIA GPU card rather than the basic PC processor (CPU).

    The Simulation Engine in InfoWorks ICM should work with all NVIDIA GPU cards that are CUDA enabled and have a Compute Level of 2.0 or better. A list of current nVidia GPU cards with CUDA support can be found at -> Obviously, we can’t be sure that the entire range of Compute Level 2.0 GPU cards from NVIDIA do actually work, or indeed what gains they offer, because we simply don’t have the resources to try them all with InfoWorks ICM! However, we have conducted tests using TESLA C2050 and C2075, Quadro 4000 and 2000 and GeForce GTX560Ti, GTX580, GTX 460M and GT 440 cards, which are some of the more popular devices, so we know for sure that they all work with InfoWorks ICM.

    There's some details of specific 2D runtimes on different CPU and GPU hardware in the Blog article Runtime comparisons for 2D models in InfoWorks ICM

    It’s important to note that your PC must have the latest, and official, NVIDIA drivers installed for the GPU to be able to process your 2D models. Generic drivers (commonly employed in corporate environments, where everyone is given a ‘standard’ install of Windows) will render the GPU card invisible to ICM.

    It’s very important to note that the GPU card plays no part at all in regular 1D calculations. Also, these cards give no advantage for 2D calculations in InfoWorks CS or RS and we will not be updating either of these applications to detect or utilise GPU technology.
