Sample Scenarios Refresh Rate

I am running the C++ sample, and simulating tension Pneumothorax.
After setting the parameters, the call to AdvanceModelTime by 120 seconds takes around 2 minutes to return.
Is this normal behavior?

    BioGears run-times do vary depending on computer. Can you please provide your computer specs?

    We are currently running anywhere between real time (1 second real time to simulate 1 second of our patient/scenario) to 5x real time (10 seconds of real time to simulate 50 seconds of our patient/scenario)

    It sounds like your machine is executing the BioGears Engine at real time. It is taking you 2 minutes to simulate 2 minutes of the patient/scenario

    Over the next year we will be working on optimizing our engine to improve run-time performance.
    At this point, I believe this is normal behavior, but again, I would be interested on the type of hardware you are running on.

  • I am running the samples on a core-i7 2600 CPU @ 3.4 GHz, with 16GB RAM.
    OS is Win 7/64.
    I will run additional tests to see the second by second behavior
  • Just FYI here... I'm running on Intel Core-i3 2.4GHz w/ 4GB RAM and Win 7 OS and am getting 50 sim-seconds per 14 real-time (3.3 sim:real)
