I have a large DEM reprojecting from lon/lat to Lambert Conformal Conic and specified the lanczos_f method to minimize smoothing (the west edge of the DEM is at the coast).
With 32G RAM in the host I specified mem=4000 in the r.proj command line. When I look at top I see that process consuming 97.5%-100.0% of the CPU (8 cores/16 threads) but only 1.5% of available memory. Since I allocated about 16% of available memory to this process why isn't r.proj using it? So far the process has been running for 2 hours; I thought that 4G of memory (rather than the default 300M) would decrease processing time. I would like to learn how to minimize processing time when modules accept a higher-than-default amount of memory dedicated to them and the maps are very large.
