Rob,

I thought I had run the Internal Solver with the ParallelSolving option several times, but the last couple of times it crashed. For what it's worth, I have attached the crash report.

I just updated the options profiles with the downsampling and saturation limit on GIT. You might want to git pull and build again to get a better solve.

I can't replicate your crash. It looks like it happened due to a logging issue. Maybe try changing the log setting to log none or maybe log verb and see if either have an effect on the crash?

I just fixed a bug with star positions when one profile is used for sextracting and a different one is used for solving. I also added some edit buttons so hopefully the profile lists are less confusing. And I made an automatic option for the parallel algorithms and put it in the FastSolving profiles

Rob,

I ran a bunch of trials between your last two changes. I haven't analyzed the results, but it seems the "FastSolving" profile is nearly optimum for both the internal sexysolver and astrometry.net.

I didn't run ASTAP solutions because an early run on blind solves (with jpegs) ASTAP failed. There was a message about atk-bridge missing; however, it was installed and I got the same message after installing the -dev package. A "locate atk-bridge" gives the following:

That sounds good, because in my last change, I modified the Parallel solving profiles so that they will automatically do multithreaded solves if it thinks it would help, but if not, then it will default back to the fast solving options. Basically it is a multithreaded algorithm auto setting. So now maybe those will be better all around, because there are times when they REALLY help the performance, but other times when they don't.

Were you able to reproduce the crash you reported earlier?

Whatever the default logging was, SexySolverTester would crash. Turning off logging or changing to verbose logging took care of it.

Ok, I think I can solve it. I will look into it. I think it is an issue only on Linux. Neither windows or Mac had an issue, but sometimes I saw the same issue on another Linux system. It is related to initialization of the logger.

Thanks for testing!

Han, I think I fixed most of these things today. #1 I think I fixed by improving the options profile and making the interface clearer. #3 I think I fixed this for the external solvers.

For #2 though, I am confused since I think it does give a warning?



It should be noted that this message prints because my SexySolver algorithm determined it could not run Sextractor since it doesn't exist. It did not try to run the command, but instead returned an error and printed this message. Is this not the warning you are looking for?

One more question Han.

Is there a version of ASTAP released somewhere so that I can try implementing INT SEP EXT ASTAP?

So I released a new version based on my fixes to all the great feedback that I got today.

I tested the new version 1.2. I tried only the internal extractor and solver using the default settings. Here are six problem files:

ufile.io/pjj8pgom

It can't solve three files. Two take too long and one file can't be opened.

Sometimes the program crashes after problem file. Didn't investigate further.

Aborting the internal solver takes too long for impatient users.
