Accelerad and HB AnnualIrradiance "workers"

Hello all,

I am running the Annual Irradiance recipe using the Python API. I have also setup to run Accelerad. I am curious though what the expected impact of the workers argument is in this case:

# create the settings
    rec_settings = RecipeSettings(folder, workers=workers_)

From what I can tell it certainly changes the runtime for my simulations, but it also seems to be driving the negative values I was detecting earlier this year (and still run into). For instance I can run the same scene with 4 workers and have no negative values, but once I switch to 22 workers I have many using the same parameters (runtime is reduced to 1/5th of 4 workers).

For context I run a 12 core CPU with an RTX card and 64GB of ram.

Thanks!

Hi @justinfmccarty,

When using Accelerad, you should have only one worker. Having multiple workers will cause context switching on the GPU, which will only slow the simulations down.

Excellent. Thank you for being so quick.
