Hello everyone, we are going to setup new computer mainly for acoustic simulation workflows. Here is my questions:

1. Intel and AMD processors have different core setups. For example, processors I9-14900K and R9-9950X both have 32 threads but Intel has 24 core, AMD has 16. Is there any difference in terms of AURA? What do you suggest?

2. Is there any plans to rewrite AURA to make it fast? Or is it already doing the best it can?

Thanks!

1. AURA supports up to 32 threads. In the AURA settings you can select always 32 threads. Then the systems spreads the calculation over all available CPU cores.

But in AURA only the ray-tracing calculations itself can be parallelized, but the access to the loudspeaker files and the directivity balloon calculation not.

So only in larger rooms where you run AURA with more particles, longer calculation time and scattering the ray-tracing part dominates and causes a higher CPU load over all cores.

Only then more CPU cores will calculate faster.

If you have rooms with a distributed loudspeaker system with many sound sources (e.g. shopping mall or airport terminals) a faster CPU (higher clock rate) with less CPU cores could be faster or at least not much slower.

2. Yes, there are already plans to accelerate raytracing-based calculations in EASE.

When choosing the number of processor cores does it matter if some of them are efficiency cores? If so, do you have any recommendations on this?

I think OS arranges it accordingly or maybe cpu itself based on the load.
