Batch job on affinity photo - fails

[jooles65]

Hi,

I have tried the Affinity Photo batch job option (iMac version), but only succeeded once when initially testing with 3 files, every other attempt since has failed (I have been very careful to select the options and cannot see any reason for it not working), even when again selecting a small number of files, no files get written to the destination folder and no message appears to indicate either success or failure (suggest this is a needed improvement in any case).  

Any suggestions?

Could you please provide a screenshot of the Batch Job panel just before you click OK?

Hi John,

Hi again,

Tried a re-boot, but got an error that Affinity could not shut down due to a running batch job (obviously something went wrong before) - so then did a force quit on Affinity and then was able to re boot.  Just did a test batch job and got 3 files to process.  So all seems ok.  

regards,

Julian

Hi,

Update, tried larger number of files, about 20, and did not work (no files appeared, no messages either), then tried another 2 files to see if that worked, but did not.  Back to square one it seems?

I notice that you have ticked Parallel Processing. Try unticking this. I know there seems no logic in this but it seems to cure your problem for others.

Yes, worked, but only if not ticked from the beginning of a session.  Annoying since ticked is the default.  

But note the behaviour is inconsistent since the first batch job works even when Parallel Processing is ticked, but subsequent batch jobs do not work - even if not ticked, so then you have to force quit because the batch job runs in the background and never finishes.  

Thanks for taking the time to answer.

Julian.

Well unlike with sequential program flow, here parallel computing runs several subtasks simultaneously (...also called concurrency or parallelism). The advantages are usually obvious: Parallel processing allows multi-core systems to be used efficiently and to solve more complex problems in a reasonable amount of time. However, this also goes hand in hand with a significantly higher complexity and a poorer traceability of the program code as well as a higher error rate. It looks like APh has internally some problems with race conditions and data races among threads.
