Users will care about which cells they are using. Our partial solution should allow the users to control/monitor/request/free these cells. I looked into the links https://arc.liv.ac.uk/trac/SGE/ticket/1426 and http://gridengine.eu/grid-engine-internals/102-univa-grid-engine-810-features-part-2-better-resource-management-with-the-rsmap-complex-2012-05-25 - I see that many consumable resources can be attached on host basis with RSMAP. We need to be able to attach these 300 consumable resources as shared between 4 nodes - is it possible? Maybe a separate queue for these 4 particular hosts with list of complex consumable resources? >> >> We thought that there should be 300 different (varieties) resource >> consumables in SGE for this GROUP of hosts each can be in use or free (in >> total 1 unit per resource consumable in total for this particular group of >> hosts). >>Why did you think that?

All cells are different and users will need to know which one they need to request. At this stage they all should be distinct. Any tips on the implementation, will be greatly appreciated. Thank You.
