    Hi Stefan,

    The Server was a Xeon based system running at 2.4 GHz. I don't seem to have a note of the exact model number, but it had 32GB of memory and was running Widows Server 2008R2.

    As a general rule, on the models we tested, the graph always flattened out once you were in the 20-30 cores area.

    Appreciating where the 'drop' happens is always good to know of course, as one of the features of InfoWorks ICM is that you can limit a particular simulation to a certain number of cores. This means that you can optimise runs on a powerful machine to ensure each has just the right amount of resources. For example, on the machine I was using we experimented with limiting the cores/threads available to an individual simulation. We found that 8 threads seemed to work well, which allowed us to run 4 concurrent simulations and still leave enough resource for the Server to manage regular background Windows tasks.

    Does that type of set up require 4 licences? One for each simultaneous simulation?

    No! For the example above you only need 1 seat/licence. The ICM licence provides authority for a particular PC or Server to run simulations. If the machine is a powerful server then you can make it run concurrent simulations (as above). If you wanted to run four simulations on four different machines at the same time, then you would need four licences/seats.

    By comparison, products like InfoWorks CS or InfoSWMM can only perform one simulation at a time with a single licence.

    These are really good tips, Andrew.

    I did want to mention that we also have the ability to select the number of cores used during the simulation for InfoSWMM and H2OMAP SWMM. We limit the number of cores to 8. We also allow the user to save only a Domain or Selection Set to make the output file smaller those models run in continuous simulation that may generate GB's of binary output files if the whole network is saved.
