Hi,
I am using SGE 6.2u5 on RHEL5.
Users in our company run a lot of multi-core simulations via SGE and parallel
environment like this:
$ qconf -sp local
pe_name local
slots 1000
user_lists NONE
xuser_lists NONE
start_proc_args /bin/true
stop_proc_args /bin/true
allocation_rule $pe_slots
control_slaves FALSE
job_is_first_task TRUE
urgency_slots min
accounting_summary TRUE
The jobs go into this queue:
$ qconf -sq mmtoken.q
qname mmtoken.q
hostlist @nb-lin @nb-lin-aux @nb-lin-mmtoken
seq_no 5,[@nb-lin-mmtoken=1],[@nb-lin-aux=10]
load_thresholds np_load_avg=0.75,localdisk_free=300G,mem_free=3G, \
mmtoken=20
suspend_thresholds NONE
nsuspend 1
suspend_interval 00:05:00
priority 0
min_cpu_interval 00:05:00
processors UNDEFINED
qtype BATCH INTERACTIVE
ckpt_list NONE
pe_list local make
...
According to documentation, I'd expect that the allocation rule "$pe_slots"
helps to fill the hosts more or less equally, with priorities defined by the
different seq_no settings in the queue.
However, I frequently see that hosts are filled unevenly, and new jobs with
multiple slots are often added to hosts already running other jobs instead of
being assigned to hosts with a lower load.
Does anybody happen to know how this could be influenced?
Regards,
Manfred
