A lot of time ago it was formulated simple rule for swap partition size (equal to main memory size). Currently we all have relative large RAM on the nodes (typically, I beleive, it is 2 or more GB per core; we have 16 GB per dual-socket quad-core Opteron node). What is typical modern swap size today? I understand that it depends from applications ;-) We, in particular, practically don't have jobs which run "out-of-RAM". For single core dual-socket Opteron nodes w/4GB RAM per node and "molecular modelling workload" we used 4 GB swap partition. But what are the reccomendations of modern praxis ?
