A fast parallel du type thing. This tool has two main goals:
- Fast scans on filesystems with slow
statcalls, e.g. Lustre filesystems - Separate the filesystem scan from the presentation of the results to allow cheap queries from the results of a single slow scan.
The first goal is accomplished by distributing the stat calls to multiple
parallel workers. This allows much quicker scans, but may make your sysadmin
unhappy by thrashing the filesystem with metadata queries. Caveat emptor.
