UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Before I release it, I will make sure that everything is working properly and then I will release it.
I use APP for all of my processing and I noticed that when I use the computer with the 64 core 128 thread setup APP seems to limit itself to showing 64 threads and using 63 threads. Is there a way around this? I already knew it wouldn't recognize a second processor in a dual processor setup, but I was surprised that it seems to limit itself to 64 threads. Before anyone says that it is showing 64 cores, it is not, because on my old 18 core/36 thread setup it always showed as #36 CPU and on the dual Xeon E5-2696 setup it shows #44 CPU for using one of the 22 core/44 thread processors.
Hi @imnewhere,
The amount of threads that APP can work with is not limited by our own code I think. It must be caused be the code of our development platform which detects the hardware and thus the amount of available threads.
Maybe that AMD Epyc 7742 cpu is not yet fully supported for the latest Oracle GraalVM JDK that we use, it is based on Oracle Java JDK 21. I would expect it to work correctly...
I see from AMD's specification : https://www.amd.com/en/products/cpu/amd-epyc-7742
that it does have 128 threads like you indicate, so normally APP would let you use it.
I will do some more research 😉 thank you for notifying me about this !

I noticed something similar.
I am using a dual EPYC 7551 system, 2x 32 cores.
In Windows 10 Pro APP only uses 64 threads. In Linux it uses 128 threads (but it seems much slower and fills up all the usable RAM).
