Hi

just got the new AURA 4 (64-Bit- no 1 GB limit) with EASE 4.4.61.16

the RAM limit is not an issue and didn't get any problems BUT it is not using my 16 Threading multi core processor! that is frustrating Sad

it consumes a lot of time and act like a diver whom take a long breath on surface then dives for 20 seconds and come back and take 5 minutes or more then dives for 20 sec..... and so on!

once a calculation starts it should continue using the threading until simulation is finished.

here is a screen shot of the processor with AURA 4 in action like a diver:

1- Is there any setting that i should use to fully utilize my CPU for AURA 4 calculation?
2- Is there something in Windows 10 i should update/enable/disable that will result into fully utilizing CPU for AURA 4?
3- Does it support multi-node network (farm) utilizing multiple computers for such calculation?

Finally, How on earth can I get a TRUE multi-threading CPU utilization on EASE with AURA?

Beat regards,
Hamza

Hamza,

I'm running AURA v4 on a laptop (WIN10Pro) and larger multi-thread computer (WIN Server2016) without problems. I'm able to achieve 100% CPU utilization on both computers with detailed EASE models and many active GLLs. While there maybe some short periods of lower activity, the 100% CPU utilization is typically stable for many hours.
I have certainly appreciated the improved performance that AURA v4 provides.

Can you describe a little more about your setup and your EASE model?

Hi,
I have a similar problem as Hamza. Aura v4 starts calculations and 100% load on processors, but with about 30% of calculations it slows down and the load on processors decreases to 10%, and the calculation time increases instead of decreasing. I tried on fast and medium settings, restarted the PC and the same every time.
On v3 Aura there was no problem.
What's happening?

Hi,

first please note that 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.

In order to check the behavior that occurred to you, it would be helpful, if you could provide your EASE project to our technical support (support@afmg.eu).
