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.
Hi. I am having a large (24" f/3.3) welded aluminum Dob built, on a dual-axis equatorial platform, so it will be capable of imaging. At 2313 mm FL after the 3" Big Paracorr, I will be able to bin my ASI6200MM pixels 3X (1.00 arc-sec/pixel) or even 4X (1.34 arc-sec/pixel), and with such large pixels (11.3 um and 15.0 um), I will be able to use really short exposures and still swamp the read noise at my 21.2 SQM imaging site. But the downside of exposures in the 5 to 30 second range is a LOT of images to register and stack. Each image is 120 MB, and there could easily be hundreds, if not a thousand of them to process. My understanding is that APP can handle all of the cores and threads you can throw at it, which under Windows 10 maxes out at 32/64. So AMD Threadripper 3970X. My questions relate to the right amount of DRAM, how that breaks among DRAM sticks (so how many), and about the M2 SSD(s). I am currently looking to use G.Skill Trident Z Neo DDR4 3200 CL14. My questions are:
- Is 3200 CL14 (14-14-14-34) still the highest performance option?
- For 32 GB, is 4x8GB better than 2x16GB?
- Would 64 GB be better than 32 GB? That would be 4x16GB.
- On the M2 SSD front, I am holding out for Samsungs imminent launch of their 980 Pro PCIe 4.0 M2 SSD.
- That will be available in up to 1 TB capacity. Would that have benefits over the 500 GB version?
- My MB choice, the Asus Prime TRX40-Pro S, has room and cooling for two M2 SSDs. Would their be any advantage to adding a second M2 drive, and putting the OS and APP on that? If so, can I assume that it would also want to be PCIe 4.0 and fast? What capacity would be best?
Thanks!
All the best,
Kevin
Hi Kevin,
So I’m not super into the latest PC technology, but 3200 memory seems plenty fast still. The timings and optimal memory configurations are usually something for games optimization (or overclocking to the edge of stability, which I wouldn't recommend for a processing computer). I don’t think it’ll make a huge difference for APP’s processing. If you can afford the best, indeed a threadripper is amazing, APP uses as many cores as you have. If 64GB is an option choose that. That SSD is going to help you a lot as well, in this case it doesn’t really matter what size, so I guess the more the better as well, especially when your projects are that big.
In the future APP will also harness the power of the GPU. It’s not necessary to buy the best right now as it isn’t in yet. Personally i would buy a decent GPU and wait for that option and buy a good one then.
Thanks, Vincent.
All the best,
Kevin
