I am not quite sure. It seems that your AR (advance reservation)
snapshot3 build is a bit new, and it may be a problem coming from it. I
am not quite familiar with this new SGE feature. I'd ping the gridengine
list to check on that error message coming from execd.

Hello everyone,
I am facing problem while calling mpirun in a loop when using with
SGE. My sge version is SGE6.1AR_snapshot3. The script i am submitting
via sge is
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
let i=0
while [ $i -lt 100 ]
do
echo
"############################################################################################"
echo "Iteration :$i"
/usr/local/openmpi-1.2.4/bin/mpirun -np $NP -hostfile
$TMP/machines send
let "i+=1"
echo
"############################################################################################"
done
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Now above script runs well for 15-20 iteration and then fails with
following message
-------------------------Error
Message-------------------------------------------------------------------
error: executing task of job 3869 failed: execution daemon on host
"n101" didn't accept task

-----------------------------------------------------------------------------------------------------------
When i do ssh to n101, there is no orted and qrsh_starter running. While
checking its spool file, i came across following message
-----------------------------------------------Execd spool Error
Message---------------------------------
|execd|n101|E|no free queue for job 3869 of user neeraj@n199 (localhost
= n101)
-----------------------------------------------------------------------------------------------------------------------
What could be the reason for it.
While checking the mailing list, i come across following link
http://www.open-mpi.org/community/lists/users/2007/03/2771.php
but, i dont think its the same problem. Any help is appreciated.
