Hi everyone,
I was recently working on a daylight simulation and found that it took a lot of time to complete.
As shown in Figure 1, after simulating the system build with version 1.5 of ladybug, it can be seen through the resource manager that only a few individual cpu cores are involved in the computation and a large number of cores are not being utilized.
- Fig.1
As shown in Figure 2, my previous daylight simulation system built with 0.66 & 0.69 version of ladybug software will use all cpu cores for parallel calculation, especially multiple python calculation windows will pop up on the desktop, only one window will pop up when I use 1.5 version of the software for simulation?
- Fig.2
Is it the new version of ladybug that redesigned the computational logic of radiance, thus making parallel computation impossible? This problem is causing me to spend several times more time than before on simulations, so I hope someone can answer this question!
Have a nice day.
