Subject: [OMPI users] Locker memory Limits error
From: thomas.forde_at_[hidden]

hi guys

im having a strange problem when starting some jobs that i dont uderstand.

its just 1 node that has an issue and i find it odd.

The OpenFabrics (openib) BTL failed to initialize while trying to
allocate some locked memory. This typically can indicate that the
memlock limits are set too low. For most HPC installations, the
memlock limits should be set to "unlimited". The failure occured
here:

  OMPI source: btl_openib_component.c:1066
  Function: ompi_free_list_init_ex_new()
  Device: mlx4_0
  Memlock limit: 65536

i have rechecked and verified everywhere that the limit is set to
"unlimited".

i can run the same job on other nodes and they have no problems, just so
strnage that this one node crashes.

running open_mpi 1.4.5

not sure where to look next.

this node was working 2 days ago, but after a reboot it has changed to
this.
