Hi All, I have recently set up a slurm cluster with my servers and I'm
running into an issue while submitting GPU jobs. It has something to to
with gres configurations, but I just can't seem to figure out what is
wrong. Non GPU jobs run fine.
The error is as follows:
sbatch: error: Batch job submission failed: Invalid Trackable RESource
(TRES) specification after submitting a batch job.
My batch job is as follows:
#!/bin/bash
#SBATCH --partition=tiger_1 # partition name
#SBATCH --gres=gpu:k20:1
#SBATCH --gres-flags=enforce-binding
#SBATCH --time=0:20:00 # wall clock limit
#SBATCH --output=gpu-%J.txt
#SBATCH --account=lnicotra
module load cuda
python gpu1
Where gpu1 is a GPU test script that runs correctly while invoked via
python. Tiger_1 partition has servers with GPUs, with a mix of 1080GTX and
K20 as specified in slurm.conf
I have defined GRES resources in the slurm.conf file:
# GPU GRES
GresTypes=gpu
NodeName=tiger[01,05,10,15,20] Gres=gpu:1080gtx:2
NodeName=tiger[02-04,06-09,11-14,16-19,21-22] Gres=gpu:k20:2
And have a local gres.conf on the servers containing GPUs...
lnicotra@tiger11 ~# cat /etc/slurm/gres.conf
# GPU Definitions
# NodeName=tiger[02-04,06-09,11-14,16-19,21-22] Name=gpu Type=K20
File=/dev/nvidia[0-1]
Name=gpu Type=K20 File=/dev/nvidia[0-1] Cores=0,1
and a similar one for the 1080GTX
# GPU Definitions
# NodeName=tiger[01,05,10,15,20] Name=gpu Type=1080GTX File=/dev/nvidia[0-1]
Name=gpu Type=1080GTX File=/dev/nvidia[0-1] Cores=0,1
The account manager seems to know about the GPUs...
lnicotra@tiger11 ~# sacctmgr show tres
Type Name ID
-------- --------------- ------
cpu 1
mem 2
energy 3
node 4
billing 5
fs disk 6
vmem 7
pages 8
gres gpu 1001
gres gpu:k20 1002
gres gpu:1080gtx 1003
Can anyone point out what am I missing?
Thanks!
Lou
