Host Range

For example, if the majority of workloads on the cluster use between
4
and
16
hosts, set these numbers as the lower and the upper bounds, through the
-hr <n:m>
option:
> mpitune ... -hr 4:16
The
mpitune
utility scans all hosts in the rage between
4
and
16
whose numbers are powers of
2
. For the example above, it creates tuned settings for
4
,
8
, and
16
hosts.
