Re: [HTCondor-users] NUM_SLOTS=1 in 23.x creates partitions?

["Beyer, Christoph" <christoph.beyer@xxxxxxx>]

Hi,

that is the difference of a static and a partitionable slot (maybe wording is a bit different) the partitionable slot carves of a child slot that runs the job and the rest of the parent slot is negotiated in the next round. The static slot is negotiated as a whole and stays a single slot no matter how much smaller the actual job running in it is.

both slots on one EP

NUM_SLOTS = 2

static slot:

SLOT_TYPE_1 = cpu=1, memory=8000
SLOT_TYPE_1_PARTITIONABLE = false

partitionable slot

NUM_SLOTS_TYPE_2 = 1
SLOT_TYPE_2_PARTITIONABLE = true

Best

Betreff: [HTCondor-users] NUM_SLOTS=1 in 23.x creates partitions?

Does NUM_SLOTS=1 limit the machine to having only 1 slot in 23.x?  I've noticed in both 23.3 and 23.0 that slot1 is getting divided into slot1_1 and slot1_2 and 2 jobs are running where as 10.x and before didn't.

Or is there now another way to say I only want 1 slot on the machine regardless of how many cores it has?
