KNOWN ISSUES
============

Only for HPC based clusters - do not run openSM on the head-node.

For all other Windows OS flavors, openSM works correctly.

If openSM is enabled (install feature 'OpenSM Started') on the head-node of an HPC cluster, 25% of the head-node CPU is consumed doing unknown processing - under investigation.
An external SM (embedded or OFED) configures an HPC cluster as expected, with no observed problems.
