Grid Engine: 1)Give a lot of flexibility to the administrator. This makes it easier for the admin to do things the designers didn't anticipate. It is less a batch scheduler more a batch scheduler construction kit with a reasonable sample configuration. Despite attempts to port it to Windows Grid Engine is basically a unix batch scheduler and follows the unix philosophy. 2)For the most part request the resources you need rather than try to tell the scheduler how to allocate jobs to nodes. Which resources you can request is up to the admin. Your actual problem isn't soluble in a configuration agnostic way but on many SGE clusters: There is a pe called smp with an allocation rule of $pe_slots. There is also commonly a resource called exclusive that can be requested to get exclusive access to a host. However this is just a common configuration and wouldn't work on the cluster I admin for example. You might choose to assume that anyone who doesn't use the configuration outlined above is familiar with their configuration and can adapt your job submission mechanism if you let them. If you want the more general ppn then the multiple PE's with allocation rules 1,2,3.. up to the largest number of cores on a single node should do it (never tried this just going by the man page).
