Optional LSF HPC features configuration

After enabling LSF HPC features, you can define the following in lsf.conf:

LSF_LOGDIR=directory

In large clusters, you should set LSF_LOGDIR to a local file system (for example, /var/log/lsf).
LSB_RLA_WORKDIR=directory parameter, where directory is the location of the status files for RLA. Allows RLA to recover its original state when it restarts. When RLA first starts, it creates the directory defined by LSB_RLA_WORKDIR if it does not exist, then creates subdirectories for each host.

You should avoid using /tmp or any other directory that is automatically cleaned up by the system. Unless your installation has restrictions on the LSB_SHAREDIR directory, you should use the default:
```
LSB_SHAREDIR/cluster_name/rla_workdir
```
On Linux hosts running HP MPI, set the full path to the HP vendor MPI library libmpirm.so.
```
LSF_VPLUGIN="/opt/hpmpi/lib/linux_ia32/libmpirm.so"
```
LSB_RLA_UPDATE=time_seconds

Specifies how often the HPC scheduler refreshes free node information from the LSF topology adapter (RLA).

Default: 600 seconds
