#2356: r.stream.basisns uses more memory than given in memory option -------------------------------------+-------------------------------------- Reporter: sbl | Owner: grass-dev@… Type: defect | Status: new Priority: normal | Milestone: 7.1.0 Component: Addons | Version: svn-trunk Keywords: r.stream.basins, memory | Platform: Linux Cpu: x86-64 | -------------------------------------+--------------------------------------
Comment(by hamish): so for an unsegmented cell map, 180752 * 141312 * 4 bytes = ~97GB to hold one whole map in ram. r.stream.basins/io.h defines segments as 256x256, so for memory=10000 (mb) {{{ seg_create_map(&map_dirs, SROWS, SCOLS, number_of_segs, CELL_TYPE); }}} we get bytes = ~20.8GB, and needs that for each of the two or three open maps. can you try r61149?
