 One node ''n37'' has been redone with latest Nvidia CUDA drives during summer 2018.  Please test it out before we decide to redo all of them. It is running CentOS 7.5 and I'm interested to see if programs compiled under 6.x or 5.x break.
-Use the ''#BSUB -m n37'' statement to target the node.

+==== ib0 ====
+We've lost the ability of bringing up interface ''ib0'' when going to 7.5 and the latest kernel.
+Details are described here ... http://www.advancedclustering.com/infinibandomni-path-issue-el-7-5-kernel-update/?sysu=bd584af325e6536411a2bc16ad41b3eb
+Reflecting on this, this is not necessarily that bad.  For GPU compute nodes we do not really need it.  This would also free up 5 infiniband ports on the switch and make the available ports a total of 7.  That could be allocated to new servers we're thinking of buying.
