Upcoming DOWNTIMES for NIH Biowulf (Biowulf)

During the next several weeks the NIH Data Center which houses the
Biowulf Cluster will be transitioning to a new Continuous Power
System.  This system will provide significantly more and reliable
power than is currently available.

However the transition will result in numerous disruptions to the
operation of the Biowulf compute nodes.  The expected partial and
total downtimes are as follows:

-- Tonight, as previously announced, half of the "e2666:c8:g24"
   nodes will briefly be powered down.

-- On the evening of July 27/28, ALL "e2666:c8:g24,g72" nodes will
   briefly be powered down.  

-- During the day on August 6, ALL compute nodes will briefly be
   powered down.

For each of these periods, jobs running on the affected nodes will
be terminated (which means ALL running jobs will be terminated on
August 6).  Queued jobs will be unaffected during all periods.

The Biowulf login node and user /home and /data directories will
remain available during each period.
