Grid engine/cluster management and job scheduler for Debian/ubuntu

I need to perform large amount of computations on a something resembling a cluster, the hardware and the OS are identical (the OS is ubuntu) but no central management software or grid engine is installed. The web search results in mostly outdated or proprietary software. I hope my question is not too general but, what are the cluster management and job scheduling options for Debian and its derivatives? For the general management of the cluster I use cssh but this approach is not very efficient when it comes to job scheduling and monitoring. I have experience using the venerable Sun grid engine RIP. Thanks for reading this!
