Memory consumption on a per user basis

[Josh Roden]

Hi
Thanks for everyone's input.
I came across and liked the smem prog for showing "fair share" mem usage
and am using it in a script that looks at RAM+SWAP limit (that I decided
on) and
it kills whoever is using the most at the time.
In the future I hope to succeed in configuring cgroups to enforce fair
sharing of
memory.
Does anyone know of a good cgroups forum?
I also wrote a script to monitor cpu, mem and users every 5 min and
accordingly
came to the decision to ask for more memory.
Thx,
Josh
