The env Setting in the Hosts File

The env setting specifies an environment variable that is to be set on this host when any job is started. The syntax of the setting is variable=value (regardless of the shell used), where variable is the environment variable and value is its value. For example,

env: SCHRODINGER_THIRDPARTY=/software/databases

To set multiple environment variables, include one env setting for each variable. Environment variables set in the hosts file take precedence over any that are set in your shell, either on the local host or the remote host.

For Open MPI parallel use, it is advisable to set one of the environment variables TMPDIR, TEMP, or TMP to a local file system, in order to avoid performance issues with temporary files. See Setting Up Queuing Systems for Open MPI Parallel Execution for more information.
