Hi all,
I manage a cluster of machines at the University of Warwick running on
Ubuntu 12.04, and SGE 8.1.3, the SGE root on our head node is in
/export/sge and is NFS shared and then mounted on /usr/sge on the nodes
(including the head). This all works correctly.
However in an attempt to modernize the cluster the decision has been
made to migrate to using Centos 7.2. This bring with it some problems in
that the old binaries (from Ubuntu) are in incompatible with Centos,
mainly it seems due to Ubuntu 12.04 using older versions of some of the
libraries.
I have downloaded and compiled SGE 8.1.9 on the Centos node, but don't
want to install it's binaries in the same directory as the Ubuntu
version as it will almost certainly break the Ubuntu version. So what I
would like to be able to do is to have both versions of the binaries
installed, however the Centos nodes will also need to be a part of the
same cluster as the Ubuntu nodes. I realize that there will be issues
with executable versions when running jobs, but I would at least be able
to verify that the SGE works on the new Centos system ahead of upgrading
the nodes.
Is this doable, and if so what is the best way of doing it.
Cheers.
Phill.
