[Gdal-dev] speeding up the gdalwarp process for mosaicing andreprojection

[Ray Gardener]

It looks like you should be able to (if you have a network) dupe the 
input file to each machine, run a copy of gdalwarp on each machine with 
custom -te params (-ts might vary on the last block), and then use 
gdal_merge.py to assemble the results.

There's also gdalwarp's -multi option, which will use two threads 
instead of one per gdalwarp instance.
