A few HPC rules of thumb:
- 1GB/s I/O throughput per 0.5TB of aggregate cluster memory
- 1MB/s I/O throughput per batch slot
- cluster nodes use as much electricity in three years as their initial purchase cost
Misc useful command: keep your du results so you don’t have to re-run them on large filesets:
du -sm * | sort -n | tee ~/`pwd | tr '/' '_'`.du.`date +%Y-%m-%d`
