StarAlignment seems to ignore thread priority

[Nocturnal]

Hi,

I was registering an image while listening to some music. The playback started to stutter while in the 'Structure Map' phase. This did not change as I lowered the maximum thread priority. Somehow PI still thinks it's appropriate to run at 'critical' priority which is absurd in itself. My PC is a general purpose machine and resources are to be shared. Music playback should continue, email should still be processed etc. Oh well, we had the discussion a long time ago but I guess it didn't stick.

In any event, even at priority 'high' PI interrupts music playback on my i7-920 based system. It should not do that. It must be a good citizen on my PC.

ACDNR same thing. Looks like this is a generic problem with PI not honoring the selected thread priority. This should be fixed quickly if it turns out this is indeed happening.

We already had this, and I was hoping it was fixed. http://pixinsight.com/forum/index.php?topic=1256.0

I think it used to be fixed but it got 'unfixed'. At least I don't remember this being a problem before installing the latests version.

Hi,

This is strange since I have not changed anything (intentionally at least) related to thread execution priorities in version 1.6.9. Could be a regression. I'll take a deep look and will release an update as required.

Thanks Juan.

I'm trying to figure out what the actual thread priority is as the threads execute on my system. No easy task. Process Explorer lists all threads but won't dynamically display their priority. When PI runs a deconvolution it even makes the cursor stutter. To me this means it's hogging the processors and starving even basic system functions.
