GPU runtime results for 2D InfoWorks ICM models (November 2017 update)

This is the fourth instalment in a series of blogs I’ve written summarising run times for 2D simulations conducted on PC hardware and NVIDIA GPU cards.  The first was in December 2012, I then followed up with a second in September 2016 and a third in June 2017.  Each blog shows how InfoWorks ICM has been designed to leverage technological improvements as soon as new hardware platforms and new GPU cards come onto the market.

The tables below give simulation runtimes for two of our standard 2D testing models that were run on a high-end AMD based Workstation containing an NVidia GeForce GTX 1070Ti GPU card and a high-end Intel Xeon Server fitted with an NVidia Quadro GP100 GPU card.

As with the previous runtime tests, the models contain 1.6 million and 3.3 million 2D elements and are 2D only datasets (i.e. no pipes or manholes).  Each model is run for a 2hr simulation using a M5-60 design storm. Rainfall is applied directly to 100% of the mesh, so all elements in the 2D zone are wet throughout the simulation (this is important, because it’s the number of wet elements that most influences the runtime, not the overall number of 2D elements in the model).

My thanks go to Alun Roberts of Shinglebrook Ltd and John Baxter of AC&E Ltd, who kindly supplied the physical hardware used to conduct the test runs with our standard Innovyze GPU Testing Database, the results of which are shown in the tables above.  If you would like more details of the physical hardware employed to conduct these tests, you can contact either Alun Roberts or John Baxter using the contact details shown below.
