Hallo to distinguished forum members,
We are interested to make a special configuration for SGE scheduler.
Let's assume we have a pool of 100 execution hosts.
We want to make 96x execution hosts to accept all jobs as usual while remaining
4x should receive jobs only after all other execution hosts are full.
A few ways. Here's one off the top of my head:
1. Change scheduler config "queue_sort_method" to "seqno"
2. Edit queue configuration to set a "seqno" value for your 96 hosts to
something like "100".
3. Exit queue configuration for the other 4 nodes to have a "seqno"
value of something larger, like "200".
Steps 2 and 3 are best done using two hostgroups: one for the builk of
the nodes, and the other remainders.
This change will tell SGE to sort *first* on the "seqno" value (lower
numbers go first), and then according to the load_formula.
