Astrometry ignoring --cpulimit

[Anshula Gandhi]

The "solve-field" command keeps running until it solves, even if it takes 1 hour.  It keeps outputting "CPU time limit reached!", but doesn't stop running.  It works on neither my Mac OS X Mavericks nor Ubuntu 14.04 operating systems.

Is there some additional flag I must include or code I must run in order to actually stop the solver once the time limit has been reached?

Example output:

Yes, this is a known bug.  See how it says it's trying field objects 21-30, 31-40, and so on?  The time limit applies for each of those phases individually, not for the whole solve process.  Sorry for the trouble.  One change you can make to work around this is to set the "inparallel" option in the config file (eg, /usr/local/astrometry/etc/astrometry.cfg).  Then the time limit will work correctly.

PS, I've very surprised that is solves at object 171-180!  Usually it solves much earlier or not at all.  Could you post an example image here, or submit to nova.astrometry.net ?

Thanks,

Oh okay thank you!  I didn't realize it worked that way (and I guess that explains why the CPU limit reached warning was showing up after every set of field objects).  I ended up working around it by using the timeout command before solve-field (ex: timeout 2m solve-field apod3.jpg).  But since the timeout command won't work on my Mac, and it isn't recommended to run "inparallel" on my 32 bit Ubuntu machine, I'm running "inparallel" on my Mac and using the timeout command on Ubuntu.  Thanks again for your prompt response.

The image I used was apod3.jpg from the astrometry/examples directory.

Sorry for the trouble... which index files are you using?

I'm using index 4211 from http://data.astrometry.net/4200/
