I benchmarked on my laptop (12 theads) and aurora (112 threads) and put the results here.
On my laptop, I was able to achieve parity between the array and raster mode by increasing lines/block per column. On aurora, I was able to reduce the difference from ~3x to ~2x by doing the same.
It's unclear at the moment why there's a difference in performance.
This PR replaces raster mode in
s1_geocode_slc
with array mode inisce3::geocode::geocodeSlc
. Array mode includes compression options.With compression on with default options, a CSLC product shrunk from 1.2G to 147M (this sounds too good to be true). Output was verified correct with visualization in ipython.
Needs this isce3 PR to be merged into develop.
