Thanks for the kind words.  Yes, we installed more like a mini-Sierra 
machine which is air cooled.  There are 46 nodes of the IBM AC922, two 
socket, 4 V100 where each socket uses the SMT threading x4.  So two 16 
core chips, 32/node, 128 threads per node.  The GPUs all use NVLink.

There are two EDR connections per host, each tied to a CPU, 1:1 per rack 
of 12 and 2:1 between racks.  We have a 2P scratch filesystem running 
GPFS.  Each node also has a 3T NVMe card as well for local scratch.

And we're running Slurm as our scheduler.

We'll see if it makes the top500 in November.  It fits there today but 
who knows what else got on there since June.  With the help of nVidia we 
managed to get 1.09PF across 45 nodes.
