problem with cleanmask_localrms #1504

Open ktrehaeven opened 1 year ago

ktrehaeven commented 1 year ago

Hi

I seem to have encountered a problem with the cleanmask_localrms option of the selfcal worker. WSClean runs fine for an hour and then dies with Signals.SIGABRT: 6. Log files attached. log-caracal.txt log-selfcal-image-field0-iter1-20230421-085246.txt

The exact same run without cleanmask_localrms finishes without errors

Hi @ktrehaeven, it looks like things have fallen over because of too many sub-images. I suggest re-running with fewer sub-images (parameter img_nrdeconvsubimg in the self cal worker), according to WSClean (see more discussion on parallelisation in WSClean: https://wsclean.readthedocs.io/en/latest/parallel_deconvolution.html). Likely what is happening is that the sub-image size is inappropriate given the localrms window.
