Gerard, The fix is included in SGE6.2u5 p1 & p2, and GE 2011.11, and was used by Dave's Son of Grid Engine until he copied another fix from Univa.
The fix or workaround in Open Grid Scheduler is safe until we almost run out of addressable memory in 64-bit (so we are talking about 8589934592 TB of memory usage per process), and it does not introduce compatibility issues - SGE6.2u5 p1 & p2, and GE 2011.11 can be safely mixed with SGE 6.2u5 daemons. On a related note - the fix in Open Grid Scheduler and the related execd code will be written in a year or 2, as it is currently quite messy (this applies to all versions and forks of Grid Engine). With the re-write we will be able to get rid of the current limitations (and we will discard the workaround as well), and yet there are still no compatibility issues. All tarballs from the "Open Grid Scheduler download area" have the fix, and you can simply recompile or download the tarball from dropbox and get the updated execd to replace your old execd. http://gridscheduler.sourceforge.net/CompileGridEngineSource.html http://dl.dropbox.com/u/47200624/ge2011.11-x64.tar.gz Rayson On Wed, Jan 4, 2012 at 1:01 PM, Dave Love <[email protected]> wrote: > Gerard Henry <[email protected]> writes: > >> hello all, >> after trying some files, i think i hit this bug: >> http://arc.liv.ac.uk/pipermail/gridengine-users/2010-March/029549.html >> >> does this mean that the bugfix is included in OGS, in the SGE62.u5p2 ? >> http://sourceforge.net/projects/gridscheduler/files/ >> or in SGE8 ? >> any chance to get just the needed files to upgrade my current >> installation? or do i need to reinstall with the latest release? > > If this is the bug I think it is, there's a kludge in OGS and a fix from > Univa in SGE8.
