Hi,

Finally I got it working. I also thought that it was no longer needed in
linux host but it hasn´t worked for me until I activated
"execd_arg  ENABLE_BINDING=true". I am using OGS 2011.11

First I did some testing in just one node:

[pescobar][mem01][~]$ qconf -sconf fry
mailer                       /usr/bin/mail
xterm                        /usr/bin/X11/xterm
execd_spool_dir         /scratch/sge_spool
execd_params           ENABLE_BINDING=true

and started working:

[pescobar][mem01][~]$ qstat -cb -j 5162|grep binding
binding:                    set linear:1
binding    1:               ScCCCSCCCC

So now I have modified the global config to enable it in all my exec nodes:

[pescobar][mem01][~]$ qconf -sconf|grep execd_params
execd_params                 ENABLE_BINDING=true

I have tested that if I submit a job which takes 4 cores using "qsub
-binding set linear:1" in the exec_node just 1 core works, so it seems to
be working as expected :)

many thanks!
Pablo.
