For Non-HTCondor Batch Systems

This page contains information about job routes that can be used if you are running a non-HTCondor pool at your site.

Setting a default batch queue

To set a default queue for routed jobs, set the variable default_queue:

```hl_lines="3"
JOB_ROUTER_ROUTE_Slurm_Cluster @=jrt
  GridResource = "batch slurm"
  default_queue = osg_queue
@jrt

JOB_ROUTER_ROUTE_NAMES = Slurm_Cluster
```

Setting batch system directives

To write batch system directives that are not supported in the route examples above, you will need to edit the job submit script for your local batch system in /etc/blahp/ (e.g., if your local batch system is Slurm, edit /etc/blahp/slurm_local_submit_attributes.sh). This file is sourced during submit time and anything printed to stdout is appended to the generated batch system job submit script. ClassAd attributes can be passed from the routed job to the local submit attributes script via default_CERequirements attribute, which takes a comma-separated list of other attributes:

```
SET foo = "X"
SET bar = "Y"
SET default_CERequirements = "foo,bar"
```

This sets foo to the string X and bar to the string Y in the environment of the local submit attributes script.

The following example sets the maximum walltime to 1 hour and the accounting group to the x509UserProxyFirstFQAN attribute of the job submitted to a PBS batch system:

```hl_lines="4 5 6"
JOB_ROUTER_ROUTE_Slurm_Cluster @=jrt
     GridResource = "batch slurm"
     SET Walltime = 3600
     SET AccountingGroup = x509UserProxyFirstFQAN
     SET default_CERequirements = "WallTime,AccountingGroup"
@jrt

JOB_ROUTER_ROUTE_NAMES = Slurm_Cluster
```

With /etc/blahp/pbs_local_submit_attributes.sh containing:

#!/bin/bash
echo "#PBS -l walltime=$Walltime"
echo "#PBS -A $AccountingGroup"

This results in the following being appended to the script that gets submitted to your batch system:

#PBS -l walltime=3600
#PBS -A <Incoming job's x509UserProxyFirstFQAN attribute>
