[Bioclusters] Which Sun Grid Engine?

[Chris Dagdigian]

SGE 6.x still retains the flexible paradigm where users request the  
resources they need to be successful and (in most cases) the SGE  
scheduler will place the job into the appropriate queue. What is new  
in SGE 6 is the concept of cluster queues which can span multiple  
execution hosts. The feature is more of an admin or ease-of- 
management thing than any fundamental change in the flexible way that  
SGE matches job requirements to available resources.

I wrote this document a LONG time ago but it still covers the  
differences in SGE 5/6/N1GE in some detail, including cluster queues:

N1 Grid Engine 6 (N1GE 6)"
