Hi all,
I need to give the possibility to the user to reserve one or more node
for exclusive use for their runs.
It is a mixed environment and If they don't reserve the node for
exclusive use, the serial and low number of core jobs will fragment
the availability of cores across many nodes.
The problem is that now the "exclusive" jobs are not listed anymore in
the "per queue" qstat:
We solved the exclusive request by setting up a new complex:
# qconf -sc excl
#name shortcut type relop requestable
consumable default urgency
#--------------------------------------------------------------------------------------------------
exclusive excl BOOL EXCL YES
YES 0 1000
and setting on every node usable in this way the relative complex (is
there a way to set this system wide?):
#qconf -se n0108
hostname n0108
load_scaling NONE
complex_values exclusive=true
load_values arch=linux-x64,num_proc=20,....[snip]
processors 20
user_lists NONE
xuser_lists NONE
projects NONE
xprojects NONE
usage_scaling NONE
report_variables NONE
now it I submit a job like:
$ cat sleeper.sh
#!/bin/bash
#
#$ -cwd
#$ -j y
#$ -q E5m
#$ -S /bin/bash
#$ -l excl=true
#
date
sleep 20
date
$
All works as expected except qstat:
a generic 'qstat' report:
job-ID prior name user state submit/start at
queue slots ja-task-ID
-----------------------------------------------------------------------------------------------------------------
876735 0.50601 sleeper.sh s.bridi qw 05/04/2015 12:20:45
1
and the 'qstat -j 876735' report:

while the
