Description
Hi there,
Trying to use SGE core binding feature, I'm facing strange binding strategy in the generated pe_hostfile.
If I submit a dmp job with " -binding pe linear:slots " every node in the pe_hostfile seems to get the same binding strategy.
Below are 2 examples of strange pe_hostfiles and corresponding qsub options :
#################### example 1 ####################
qsub -q batch -pe dmp* 64 -binding pe linear:slots simple.job
part061.u-bourgogne.fr 12 batch@… 0,0:0,1:0,2:0,3:0,4:0,5:1,0:1,1:1,2:1,3:1,4:1,5
part081.u-bourgogne.fr 12 batch@… 0,0:0,1:0,2:0,3:0,4:0,5:1,0:1,1:1,2:1,3:1,4:1,5
part065.u-bourgogne.fr 12 batch@… 0,0:0,1:0,2:0,3:0,4:0,5:1,0:1,1:1,2:1,3:1,4:1,5
part060.u-bourgogne.fr 11 batch@… 0,0:0,1:0,2:0,3:0,4:0,5:1,0:1,1:1,2:1,3:1,4:1,5
part083.u-bourgogne.fr 10 batch@… 0,0:0,1:0,2:0,3:0,4:0,5:1,0:1,1:1,2:1,3:1,4:1,5
part082.u-bourgogne.fr 7 batch@… 0,0:0,1:0,2:0,3:0,4:0,5:1,0:1,1:1,2:1,3:1,4:1,5
#################### example 2 ####################
qsub -q batch -pe dmp* 18 -binding pe linear:slots simple.job
part065.u-bourgogne.fr 6 batch@… 1,0:1,1:1,2:1,3:1,4:1,5
part061.u-bourgogne.fr 12 batch@… 1,0:1,1:1,2:1,3:1,4:1,5
It looks like the first binding strategy for the first host is calculated right but is wrongly applied to all other nodes.
I'm using sge-8.1.8.
All my dmp PEs (1 per IB switch) are configured the same way :
# qconf -sp dmp_swib1
pe_name dmp_swib1
slots 1000
user_lists NONE
xuser_lists NONE
start_proc_args /usr/ccub/sge/pe/dmp/startdmp.sh -catch_rsh $pe_hostfile
stop_proc_args /usr/ccub/sge/pe/dmp/stopdmp.sh
allocation_rule $fill_up
control_slaves TRUE
job_is_first_task FALSE
urgency_slots min
accounting_summary FALSE
qsort_args NONE
Feature or bug ?
Thank !

Sorry this got missed originally.
The entries in the pe_hostfile aren't used to set up the binding -- that's worked out by the execd.
