Please come all to AstroFest in London to ask us (Mabula & Vincent) questions and to see live demos of APP!
2023-01-19: APP 2.0.0-beta13 has been released !
!!! Big performance increase due to optimizations in integration !!!
and upgraded development platform to GraalVM 22.3 based on openJDK19
We are very close now to releasing APP 2.0.0 stable with a complete printable manual...
Looking for hardware specs for a top-end laptop for AstroPixelProcessor. I assume the more cores the better, lots of memory (32Gig up), powerful GPU and lots of fast drive space. Should I be looking for Intel or AMD Ryzen?
Yep, that's right, the more cores the better. Regarding a laptop I would also look for one that has proper cooling (laptops throttle down faster than a desktop usually), 32GB should be plenty but of course, more is nice as well. The GPU isn't being used that much yet, so that's for a future version. If however you can't change the GPU (usually you can't) then a powerful one would be good to have. Ryzen currently has the better CPU's it seems.
If you don't need to be mobile for processing, maybe also look at desktops? They tend to be cheaper faster and you can still exchange components for the future.
@vincent-mod Hi Vincent - thanks!
For curiosity sake, how many cores is too much or unnecessary? There is a Threadripper processor with 64 cores, 128 threads for as much as a top end computer. Would APP even use that many? I'm thinking 16 may be the sweet spot?
I don't think there is a hard limit on the cores, I believe Mabula is using one with that many (not sure). If you have a big dataset and APP can chop it up in 128 threads it will.
@vincent-mod Thanks! It’s just that taking hundreds of subs with these new larger CMOS sensors really need a lot more processing power.
For sure yes, of course APP does become faster with each update usually and I hope we can add GPU support somewhere down the line, that would make quite a difference as well.
