Mar 28 2026 APP 2.0.0-beta40 will be released in 7 days.
It did take a long time to have the work finished on this and itĀ will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...
Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
Use the GPU for heavy graphical calculations and displaying the image in the preview pane to speed up processing even more (program is already rather quick especially for registration ;-).
Thank you Rob,
The necessary libraries for GPU calculations on the GPU cores besides the CPU cores are already compiled into APP, so work will start soon on this š
For some calculations I intend to spread the work over the GPUs & CPUs, but I'll need to make smart concurrency implementations to get this working correctly on all systems.
It would enable image drawing and the preview filter to work much friendlier and hopefully faster.
Multi core tasks like registering, star analysis, normalization, integration, data interpolation (lanczos etc) could get very significant speedups once I have got it working š
(In systems where there is a good GPU, speedups could easily be more than 2x)
What really interesting will be, is to see what effect the GPU will have on multiple view regression algorithms. These calculations consist of rather complicated algebra with huge matrices.., probably the GPU will show it's strenght there particularly. For simple calculations like adding and subtracting, the GPU really has no big advantage over a CPU in terms of speed of calculation per core.

Is APP now using the GPU? Im considering to buy a new laptop as my surface pro 2017 with 4 GB RAM is very slow with APP and integration takes me almost 3 h... so would a laptop with good gpu make a big difference?
Not yet, it will be when APP gets support for Vulkan which Mabula is working on. It is a big feature though so that will take time still. Maybe it's also an idea to look at desktops? They are usually cheaper and more powerful, a nice desktop GPU will then help a lot when Vulkan is supported.
I have an old bitcoin miner with multiple gpu. Will the gpu update support multiple gpu processing?
Good question, I have no idea. But since Mabula has programmed APP to be multi-threaded, which is already challenging, I think he will definitely look at that as well and if it would speed things up even more, he will definitely be interested. @mabula-admin
Hello,
For laptop owners, gpu support will change a lot.
I have a Macbook pro 15" (8 cores) with an e-GPU (AMD Vega 56), for example the difference is really huge for video processing (DaVinci Resolve)
I await this functionality in APP with great interest 😊
I'd like to add my name to the list.Ā I've long thought that these mathematically intensive applications would be well suited to take advantage of GPUs.Ā It seems that CUDA has become the standard.Ā While I don't care for single-vendor solutions they do have ~75% of the market share.Ā The first stacking/processing software to take advantage of GPUs will have a big advantage IMHO.Ā I'd really, really like for APP to be that package.Ā I'll be happy to beta test. š
Yeah we know for sure. Mabula is working on Vulkan support, but that's still a rather big mountain to climb. It's however high up the list, together with moving to Java 11 etc.
It is certainly a major undertaking!Ā I've played with CUDA a little bit and it takes SIGNIFICANT planning to get to a place where you can start throwing work units at the GPU.
Can. Not. Wait!
Vulkan support has been stated as in progress for two years now.Ā Some sort of progress tracker might help calm the fears of those waiting for years.Ā This one is from a video game but I think they do a very good job of communicating what is being worked on, when to expect it and when that task is complete.Ā Working in an AGILE environment this is an every day thing.Ā Something along these lines would be fantastic to have for APP.Ā Even if it's a blog entry that's updated monthly.

Ah agile. Yeah we're not a fan of that kind of system, though I know companies these days like it. Instead of sprints we like to get the stuff absolutely right (of course within a normal timeframe) before release. š (little teasing sorry). Besides that, Mabula is still the main developer at this time, so that system would make less sense then as well. We do like the Github approach and as we get more developers, that will be a nice system for a small team.
But I do agree a progress overview would be nice, at least we have the overview of what is upcoming ( https://www.astropixelprocessor.com/community/release-information/). Mabula is expanding the company slowly, we will look closer at streamlining certain things in the coming year. Vulkan is still a slow one because it involves a rather big rewrite of portions of the program and other priorities are still in the way. First thing will be Java 11, GraalVM etc.
