I am running Grid Scheduler (fka Sun Grid Engine) on Amazon Web Services. Master node is running all the time, but I want to programmatically add nodes to the cluster (also remove - but remove is not a problem).
I launch an instance from existing AMI; during startup it POSTs it's hostname (say ip-10-11-12-13) to the master node. So, if I were doing it manually, I'd run qconf -ae and fill the template with the hostname. I would also run qconf -mconf all.q and add the new host and its number of core to the SLOTS statement.
I guess I can build a file and use qconf -Ae fname and qconf -Mconf file_list. Is there a way to do such updates without awk/sed file tinkering?
Edit: I am familiar with MIT StarCluster; but for variety of reasons we are not using it.
