The diagram below shows the SubmitOnce workflow when there are two Grid Engine clusters (one local, one remote):
Appendix B: Configuring Grid Engine Clusters with No Shared SubmitOnce Home Directory
Though not recommended, it is possible to configure SubmitOnce to use an $SO_HOME directory that is not shared within a given Grid Engine cluster. Using this approach, file transfer jobs are run on the head node instead of on execute nodes. To do this, follow the steps below:
Create $SO_HOME on each head node, owned by the cycle_server user.
Define a string complex on each submitter called “slot_type” and set the value to “master”. Follow the steps below to define this complex.
Edit the list of complex attributes by running the command:
Add a new line:
slot_type slot_type RESTRING == FORCED NO NONE 0
Run the following command to open the submitter’s configuration:
qconf -me submitter_host.example.com
Add or edit the existing “complex_values” entry to include the following:
Make sure that each head node has a number of slots equal to the desired concurrent file transfers you wish to allow.
In the CycleServer web interface, go to “Admin > System Settings” in the top right-hand menu, double-click “SubmitOnce” and uncheck the “Shared and mounted cluster-wide” checkbox.
