# Workload Manager Configuration Files Updated By CMDaemon

This appendix lists workload manager configuration files changed by CMDaemon, events causing such change, and the file or property changed.

## H.1  Slurm

| **File/Property**                        | **Updates What?** | **Updated During**                |
| :--------------------------------------- | :---------------- | :-------------------------------- |
| `/cm/shared/apps/slurm/var/etc/`         | head node         | Add/Remove/Update nodes, hostname |
| \<*Slurm instance name*>`/slurm.conf`    |                   | change                            |
| `/cm/shared/apps/slurm/var/etc/`         | head node         | Add/Remove/Update nodes, hostname |
| \<*Slurm instance name*>`/slurmdbd.conf` |                   | change                            |

## H.2  Altair Grid Engine (GE)

| **File/Property**                           | **Updates What?** | **Updated During**               |
| :------------------------------------------ | :---------------- | :------------------------------- |

| \<*GE instance name*>`/common/act_qmaster`  |                   |                                  |

## H.3  PBS Professional/OpenPBS

| **File/Property**                           | **Updates What?**         | **Updated During**               |
| :------------------------------------------ | :------------------------ | :------------------------------- |
| `$PBS_CONF_FILE`                            | head node, software image | hostname/domain change, failover |
| `/cm/local/apps/` \<*openpbs or pbspro*>`/` | head node                 | hostname change, failover        |

The default value of `$PBS_CONF_FILE` in BCM

is `/cm/local/apps/` \<*openpbs or pbspro*>`/var/etc/pbs.conf`

## H.4  LSF

| **File/Property**                          | **Updates What?** | **Updated During**               |
| :----------------------------------------- | :---------------- | :------------------------------- |
| `$LSF_ENVDIR/lsf.conf`                     | head node         | hostname/domain change, failover |
| `$LSF_ENVDIR/lsf.cluster.`\<*clustername*> | head node         | add/remove/update nodes          |
| `$LSF_ENVDIR/lsf.sudoers`                  | head node         | hostname/domain change, failover |
| `$LSF_ENVDIR/hosts`                        | cloud-director    | add/remove/update cloud nodes    |
| `$LSF_ENVDIR/lsbatch/`\<*clustername*>`/`  | head node         | add/remove/update queues         |
| `configdir/lsb.queues`                     |                   |                                  |
| `$LSF_ENVDIR/lsbatch/`\<*clustername*>`/`  | head node         | add/remove/update nodes          |
| `configdir/lsb.hosts`                      |                   |                                  |

The default value of \$LSF_ENVDIR in BCM

is `/cm/shared/apps/lsf/var/conf/` \<*`clustername`*>

On each node where the `lsfd` service runs, CMDaemon creates a symlink `/etc/lsf.conf` that points to `$LSF_ENVDIR/lsf.conf`. This is required by LSF daemons.
