A new vulnerability with Intel processors, "Zombieload", was recently discovered and discussed widely in the news. MSI will be rolling out patches to all systems starting Friday afternoon through the end of Monday to protect against this bug. Patching systems will occur in a rolling fashion so as not to interrupt running jobs. Once a job finishes on a node, the node will be patched then added back into the scheduling queue. As a result of this work, jobs may take longer to start, and some services may be temporarily unavailable. Also, during patching, there will be some performance penalties.
