RFC - ability to "pause & resume" an ongoing process

Topic starter  

Using my CMOS cameras, I often go for lots of high gain, relatively short exposures - this results in really really large image sets (my last one was 1500+ 16Mpixel exposures - see https://flic.kr/p/24WfXDM ) which take a really long time to process - I don't mind the latter so much, since we don't have all that many clear nights there's plenty of time for processing - but I do occasionally want to use the PC for other things. Right now, if I interrupt the process, I often lose hours of processing. Being able to pause processing (or dare I think it, even "save" the current state and close APP, reloading state at a later time and continuing) would allow me to interrupt APP for other stuff whenever I want, while allowing it to continue processing when I don't need the PC anymore.

Getting a faster machine isn't an option, I'm already using a Threadripper 1950x (and yes, 16-core/32 thread processing on a fast SSD is lovely) and this kind of processing can still take many hours to finish. Once my process is optimized, I fully expect to be processing many thousands of images in a "lucky imaging" type scenario, which can increase total processing time to days, making the ability to spread the task across sessions even more useful...

Hi Bart @bdeclerc,

Wow 1500+ frames, amazing, my record with APP is about 500 hundred frames I believe.

Yes, the request for project saving/loading has been mentioned and I am actually thinking about how to implement this. It's an important feature for the mentioned reasons, I agree.

Internally APP stores all data about star analysis, registration, normalization. I will need to convert that information in project files to be able to make this work properly, so I think it should be perfectly possible.

(working on a Threadrippper 1950X myself with a M2 SSD, it's pretty nice 😉 )

The RFC is on my list ToDo !

Any update on this RFC?  I lost several hourswoth of processing because APP ran out of memory when I tried to use LNC.I had to increase the memory and restarted APP to find that I had to start afresh.

Not yet unfortunately, I do know that 1.085 is a version which will address settings etc. So by then we should also check if this is possible.
