[Condor-users] partitionable slots are not returned?

[Carsten Aulbert <carsten.aulbert@xxxxxxxxxx>]

hi all,

we just started to venture into partitioning slots, the set-up on one machine 
is pretty simple right now:

SLOT_TYPE_1 = cpu=4, ram=7800, swap=30%
NUM_SLOTS_TYPE_1 = 1
SLOT_TYPE_1_PARTITIONABLE = True


This slot is then advertised correctly. However, running a couple of jobs and 
we see that the "partitioned slots" are not returned to the pool:

gpu016:~# condor_status -direct testhost

Name               OpSys      Arch   State     Activity LoadAv Mem

               Total     3     2       1         0       0          0        0

slot 1_2 was not used for about 30 minutes now, slots1_1 was idle before and a 
new job took that slot again - however, this is pretty bad, as the new job 
only requested a single core and slot1_1 had 3 cores reserved.

I cannot find anything about configuring the return into Condor, thus I assume 
it should *just* happen, any idea what's wrong here?

Cheers
