Have I written enough for anyone to say where I'm going wrong?
What version of HTCondor?
Mostly condor 8.2 (there are a few 8.4 nodes)
And is your startd using static slots (default) or partitionable slots
on your execute nodes? If you don't know the answer to this question,
it is probably static slots, but you can do
condor_status -cons partitionableslot
and if you see any results then you have partitionable slots...
It is using partitionable slots, fairly straightforwardly:
NUM_SLOTS = 1
NUM_SLOTS_TYPE_1 = 1
SLOT_TYPE_1 = cpus=100%
SLOT_TYPE_1_PARTITIONABLE = true
Now I have seen allusions to issues between partitionable slots and
preemption but not exactly what they are - I had an impression it was
something to do with evicted jobs leaving the slots fragmented, rather
than preemption just not happening.
