Discussion

• new shared stack install testing on lsst-dev7, not touching ~lsstsw
• Will find new install location for stack, steering clear of ~lsstsw, Developer documentation to change to reflect new install location. (ACTION) John, Jason to find install location
• shared stack install will only make use of weekly tags, stack should be lighter, can revisit need to purge tags later as necessary
• Waiting until GPFS ready (end of May) before rolling out lsst-dev7 into production.
• (ACTION) Benchmarking of stack builds / use on GPFS to present next meeting. Planning to remove /ssd
• Verification cluster batch environment TBD in discussions with Unknown User (kooper)
• Waiting on improvements to the stack before running DES through verification
• Data usage not projected to change at this time
