Okay, this going to be a stupid question coming from someone who's been on this list for years, but here goes...
I've just upgraded the RAM on a few cluster nodes to 32 GB (instead of 16 GB). A few users could benefit from this, so I'd like to be able to specify h_vmem or mem_free or s_vmem for jobs so that jobs requiring RAM > 16 GB go to this node. Digging through the google results, It looks like I need to do the following: 1. Make whatever complex I choose to use requestable 2. Set a default value. 3. Profit. It's step 2 that worries me. Must I set a default? My assumption is that if I do, that default will be used for ALL jobs. Is that correct? I'm worried because something tells me that no matter what default I use, it's going to break something, somewhere for someone. Is it possible to set default = NONE? Second question, is which resource is the best to use for this? h_vmem, s_vmem, or mem_free. I know mem_free is more of a "hint", and doesn't guarantee anything, and h_vmem will kill a job submitter guesses wrong. I've never seen anyone even mention s_vmem for this. Is there a reason for that? -- Prentice _______________________________________________ users mailing list users@gridengine.org https://gridengine.org/mailman/listinfo/users
