[CentOS] Simple resource manager?

I need to serialize computing job requests for two different multicore
machines, and in some near future, for a cluster. I have worked with
SGE but it requires NFS and other administrative steps, plus it seems
a bit overkill for my needs. I guess some simpler queue managing
engine may have been developed, possibly over SSH. Any pointers? TIA.
