Hi all,

we've specified NODEMEMOVERCOMMITFACTOR 2.0

From Moab doc (I did not find it in maui doc):

"The parameter overcommits available and configured memory and swap on
a node by the specified factor (for example: mem/swap * factor)."

in one of our nodes:

# free -m
             total       used       free     shared    buffers     cached
Mem:         32150      32040        110          0         34      11738
-/+ buffers/cache:      20267      11882
Swap:        32149         57      32092


checknode td713.pic.es


checking node td713.pic.es

State:      Busy  (in current state for 00:22:58)
Configured Resources: PROCS: 17  MEM: 62G  SWAP: 125G  DISK: 440G

MEM seems ok (32GB*2=64GB more or less those 62) but SWAP? why 125? is
it mem+swap*2?


Anyone who is using that parameter could confirm if they see same
behaviour as me?

# rpm -qa|grep maui
maui-client-3.3-4.el6.x86_64
maui-devel-3.3-4.el6.x86_64
maui-server-3.3-4.el6.x86_64


TIA,
Arnau
