In linux kernel since version 3.1 (release Date: 2011-10-24)
RAMster allows RAM on other machines in a cluster to be utilized
dynamically and symmetrically instead of swapping to a local swap
disk, thus improving performance on memory-constrained workloads
while minimizing total RAM across the cluster. RAMster, like
zcache2, compresses swap pages into local RAM, but then remotifies
the compressed pages to another node in the RAMster cluster.
