Option #3: Tripal Daemon Setup
Tripal version 3 has incorporated the Tripal Daemon module. This module was previously an extension but is now part of the Tripal package. The Tripal Daemon module will allow jobs to execute immediately upon submission, rather than waiting on the time set in the cron setup of option #2. This can be especially useful when end-users submit jobs such as with the Tripal Blast UI module. To enable the Tripal Daemon module use the following Drush command within your Drupal installation directory:
drush pm-enable tripal_daemon
Further documentation for setup of the Tripal Daemon will appear here in the future. For now, please see the Tripal Daemon Module page for usage instructions.
