Is that a lowercase k in k20 specified in the batch script and
nodename and a uppercase K specified in gres.conf?<br>

<div dir="ltr">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.
<div><br>
</div>
<div>The error is as follows:</div>
<div>sbatch: error: Batch job submission failed:
Invalid Trackable RESource (TRES) specification
after submitting a batch job.</div>
<div><br>
</div>
<div>My batch job is as follows:</div>
<div>
<div>#!/bin/bash</div>
<div>#SBATCH --partition=tiger_1 # partition

<div>#SBATCH --gres=gpu:k20:1<br>

</div>
<div>module load cuda<br>
</div>
<div>python gpu1<br>
</div>

</div>
<div>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</div>
<div><br>
</div>
<div>I have defined GRES resources in the
slurm.conf file:</div>
<div>
<div># GPU GRES</div>
<div>GresTypes=gpu</div>
<div>NodeName=tiger[01,05,10,15,20]

Gres=gpu:k20:2</div>
</div>
<div><br>
</div>
<div>And have a local gres.conf on the servers
containing GPUs...</div>
