[Beowulf] size of swap partition

A lot of time ago it was formulated simple rule for swap partition
(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 ?
