Yes, it is possible.
But you cannot use Easy installation tool.

If your cluster is installed ReadHat 7.2,
probary you may install by binary rpm or by source without separate partition.
(On compute host, SCore requires 50 MB on /opt and 1GB on /var/scored.)

If your cluster is installed the other distribution,
you may install redhat 7.2 on a separate partition,
and please install SCore by binary rpm or by source.

Please look at following document for binary rpm and source installation:
    http://www.pccluster.org/score/dist/score/html/en/installation/index.html

In the any methord, you must build kernel by source,
and install the kernel to be dual bootable.
This is depended by boot loader.
