Hi. This approach for "load_formula" seems ideal for our needs but I cannot get it to work with ge2011.11
Has anyone tried this with ge2011.11 and does it work? Joseph On 05/14/2012 11:49 AM, Stuart Barkley wrote:
On our systems we use: % qconf -ssconf ... queue_sort_method load ... load_formula seq_no*100+m_core-slots ... % qconf -sq small ... seq_no 20 ... s_rt 4:00:00 h_rt 4:00:00 ... % qconf -sq medium ... seq_no 30 ... s_rt 48:00:00 h_rt 48:00:00 ... This causes the system to attempt to use the queue sequence number as the primary sort order for nodes and then within the queues attempts to pack the jobs onto individual nodes. Our nodes are divided into groups with different resource limits and seq_no orders the queues in the needed order. The 'm_core-slots' component attempts to keep the larger core count systems fullest. Right now all our nodes have 8 cores so this hasn't been verified. We will shortly be adding some new systems with more cores. This seems to mostly work as desired, but like lots of things in Grid Engine other setting and actions can impact what actually happens. (I think) GE attempts to apply load adjustments when it starts new jobs so that everything doesn't end up on a single node that was the lightest load at the start of the scheduling cycle. See sched_conf for job_load_adjustments and load_adjustment_decay_time. We are using still SGE 6.2u5. Stuart Barkley
