[Condor-users] problem defining slots

[Carsten Urbach <Carsten.Urbach@xxxxxxxxxxxxxxxxxxx>]

Hi,

I just started to use condor for our cluster. The cluster has nodes
with 8 cores and 4 GPU's each. I just managed to set-up a policy such
that 4 slots are used for CPU+GPU computing and 4 for CPU only,
basically with a START statement like

START = (((SlotId < 5) && (TARGET.NeedGpu =?= TRUE)) || ((SlotId > 4) && \
        (TARGET.NeedGpu =?= FALSE)))

But I would also like to let a job consume more than one CPU (and/or GPU) at
once. For this I thought to set up partitionable SLOTS like this

SLOT_TYPE_1 = cpus=4
SLOT_TYPE_2 = cpus=4
NUM_SLOT_TYPE_1 = 1
NUM_SLOT_TYPE_2 = 1
SLOT_TYPE_1_PARTITIONABLE = TRUE
SLOT_TYPE_2_PARTITIONABLE = TRUE

But I cannot get this working: I always get 8 slots on each machine,
no matter what I do. And each slot claims to have 1 cpu (from
condor_status -l). And I cannot find the attributes
PartitionableSlot or DynamicSlot using condor_status -l.

I am using debian lenny with kernel

Linux lattice01 2.6.26-2-amd64 #1 SMP Thu Sep 16 15:56:38 UTC 2010 x86_64 GNU/Linux

with condor

$CondorVersion: 7.4.4 Oct 13 2010 BuildID: 279383 $
$CondorPlatform: X86_64-LINUX_DEBIAN50 $

which I installed using the .deb packet from the condor webpage.

Can someone tell me how to properly define the slots? Do I have to
publish the types etc. somewhere, or should the lines quoted above be
enough? 

Thanks

Carsten

For reference, here my full condor_config.local file, maybe the slots
just don't go together with one of the other options:

##  What machine is your central manager?

CONDOR_HOST = $(FULL_HOSTNAME)

## Pool's short description

COLLECTOR_NAME = Personal Condor at $(FULL_HOSTNAME)

NUM_CPUS = 8
SLOT_TYPE_1 = cpus=4
SLOT_TYPE_2 = cpus=4
NUM_SLOT_TYPE_1 = 1
NUM_SLOT_TYPE_2 = 1
SLOT_TYPE_1_PARTITIONABLE = TRUE
SLOT_TYPE_2_PARTITIONABLE = TRUE
START = (((SlotId =?= 1) && (TARGET.NeedGpu =?= TRUE)) || ((SlotId =?= 2) && (TARGET.NeedGpu =?= FALSE)))

SUSPEND        = False
CONTINUE       = True
PREEMPT        = False
KILL           = False
WANT_SUSPEND   = False
WANT_VACATE    = False
#RANK           = Scheduler =?= $(DedicatedScheduler)


##  This macro determines what daemons the condor_master will start
##  and keep its watchful eyes on.
##  The list is a comma or space separated list of subsystem names

DAEMON_LIST = COLLECTOR, MASTER, NEGOTIATOR, SCHEDD, STARTD

##  Sets how often the condor_negotiator starts a negotiation cycle. 
##  It is defined in seconds and defaults to 60 (1 minute). 

NEGOTIATOR_INTERVAL = 20

##  Disable UID_DOMAIN check when submit a job

TRUST_UID_DOMAIN = TRUE

STARTD_ATTRS = $(STARTD_ATTRS)
