SLAC is moving away from RHEL4 support (rapidly!). John Bartelt has outlined a suggested path, where we are gradually weaned off glastlnx14.
glastlnx14 is our remaining build box with limited access to a number of Fermi users/developers as well as CMT and SCons RM.
This week glastlnx14 moved into the "Internet Free Zone" meaning it is now only accessible through an internal SLAC node.
- Confirm that SCons RHEL4 builds are acceptable
- Complete the RHEL5 validation using GR v20r3p4 - as soon as possible
- Are system tests enough?
- All users migrate to use RHEL4 SCons builds of GR and we turn off CMT builds for RHEL4 - as soon as possible
- Limit users with access to glastlnx14 to those who truly will be debugging on RHEL4 as necessary. Early July
- Turn off all users other than batch access to glastlnx14 - hopefully late July/early August
- Automated GR RHEL4 builds can continue through August - where we would intend to do so through the collab meeting
Concurrently
- Johan and Fedora friends look into compat-gcc41
- Johann/Heather Test build GR on RHEL6
- Start up automated SCons RHEL6 builds for GR
- Validate RHEL6 builds
