Hi @falkamelung, SNAPHU performance depends on lots of factors including decorrelation and size of the interferogram. There is no unique solution as far as I tried that works for all interferogram. however the parameters are optional and you may change in the template and config file to work for your case study.
the top command as I see in your note above, might show two different runs one starting at 10 and 13 min, the other starting at 29, 32 min. --tile 2 1 means 2*1 = 2 processors are used although specified 3
When I run snaphu in tile mode it never finishes. For a relatively large file is runs for 40 minutes and then restarts. To solve the problem I switch off tiling by setting in
defaults/miaplpyApp_auto.cfg
:That works but unwrapping is painfully slow.
Here a number of observed suspicious inconsistencies that might help to debug:
miaplpyApp.py
produces this command including--num_tiles 3
:However, the snaphu command produced has
--tile 2 1
and --nproc 3:However, the
top
command shows foursnaphu
processes.
