RHEL 5.7 is mostly binary compatible with 5.3, the missing things are the bug fixes. SGE does not use secret system calls or hooks to get information from the kernel. SGE parses the /proc filesystem to fetch most of the low-level system information on Linux (on AIX it is a different story, but GE 2011.11 fixed this problem as well on AIX), and if your SGE 6.2u5 installation is working on your machines, then it will (or may be I should say "should") continue to work after the OS upgrade. A few things that can break SGE: Linux 3.0 (the kernel version string difference breaks an SGE shell script), AMD Opteron 6100 series (Magny-Cours) or 6200 series (Bulldozer/Interlagos ...) - if you use core binding, or memory expansion. Note that all those issues are fixed in later versions of SGE, but if you are not doing any of the above upgrades, then SGE 6.2u5 should run happily. (While upgrading to a later version of SGE is exciting and I can usually bill a few more hours to my clients, I don't usually advise sites to upgrade unless there is a feature needed in the later versions - you will find from past experience (from Sun's releases) that some default settings are different in different versions of SGE, and new bugs are introduced, etc. all those can cause issues just because upgrading looks like the "right thing to do"....) > This could be the deal breaker for me.

Yes, we (OGS) hear you... we offer an unofficial binary tarball on dropbox for the GE 2011.11 release, and will offer free binaries & rpms soon (for the next bug fix release the latest). > I'm glad to hear you guys are working more closely (and I see you > replying to me on both lists :-)) Actually, Dave also has a mailing list: https://arc.liv.ac.uk/mailman/listinfo/sge-discuss I sometimes reply to messages on Dave's list, but I hope to migrate most Open Grid Scheduler traffic to the "[email protected]" list, as it is easier to handle just 1 list.
