Re: [HTCondor-users] a question about machines in the pool and slots handling

["Valdes, Julio" <Julio.Valdes@xxxxxxxxxxxxxx>]

Hello Thomas:

Thank you very much for responding and for considering my problem.
Are those instructions that you sent something that I should add to my condor submission file ( I could send you  the file if you would like to inspect it), or within the (condor_config) file loaded when the condor service starts?.
Thank you

Hi Julio,

you might be able to realize it with CONSUMPTION policies [1], with which you could set different slot types each to a specific number of cores but keep them partitionable to also attract smaller jobs without too much waste (but I am not 100% sure).

Cheers,
   Thomas

[1]
SLOT_TYPE_1 = cpu=4
SLOT_TYPE_1_PARTITIONABLE = true ## should make the slot accept jobs with cores between 1 and 4 ## SLOT_TYPE_1_CONSUMPTION_POLICY = false
