Hello, I'm running SGE 8.1.2 from https://arc.liv.ac.uk/trac/SGE. Things are running fine by default. Now I need to set up a share policy but not sure how to approach this the best possible. The scenario is we have different groups of users and I need to give each of them a defined resource (or slots) so at any given time, each group will has a guaranty of slots. Say I have 120 slots (10 x 12 core procs) and 5 groups; math 20% (or 2 nodes), chem 50% (5), cs 10%, bio 10% (1) and other 10% (1). 1. If the cluster is idle, any user in any group can get whatever they ask for. 2. If the cluster is busy with all math users running (120 slots) and then chem user needs 50 slots, then 50 slots of math jobs will be suspended to allow chem users to run. Then if any other group needs to run, more math jobs will be suspended but math will guaranty to have at least 20 slots. Does it makes sense?
I was thinking to enable the functional share policy and actually set it up, following this instructions ( http://docs.oracle.com/cd/E19080-01/n1.grid.eng6/817-5677/i999885/index.html ) However I'm not quite clear how the number of functional tickets translates to SGE slots. Will job will be suspended or resumed by default with this setup? Or does it even do what I'm after here. Thank for your response and advice.
