Re: FIO Results & Running IO500


Actually, it's been pointed out to me I was confusing engines and
targets. So ignore me. :)

It would be sensible to increase the number of engines per node. For our
system, where we have 48 cores per node, we're running 12 engines per
socket, 24 per node. This night be too many, but I think 1 engine per
node is too few.

Johann, my configuration is as follows:

4 nodes, 4 engines in total (1 per node)
2 x 128 GB Optane per socket, 2 x sockets per node (DAOS is currently
only using 1 socket per node)
(We also have 1x 1.5 TB NVMe drive / node, that we plan to eventually
configure DAOS to use)
Nodes are using Mellanox EDR Infiniband
Cent OS 7.9, have tried various MPI distributions.

And yes, I am running FIO from one of the nodes.

Is there anything you see that I should modify or investigate? Thank you
very much for the help!
