Hello Guys,

    I tried integrating SGE with 3rd party checkpointing library say 
condor and BLCR, but unable to checkpoint the application. On searching 
the mailing list i found an issue below

        http://gridengine.sunsource.net/issues/show_bug.cgi?id=2037

   I am able to checkpoint the condor, if i manually send the 
application USR2 signal, but on suspending queue/job, the SGE is not 
checkpointing the application.
 The configuration of Condor chekpoint is as follows

 >  qconf -sckpt check_transparent
ckpt_name          check_transparent
interface          TRANSPARENT
ckpt_command       NONE
migr_command       NONE
restart_command    NONE
clean_command      NONE
ckpt_dir           /home/neeraj/checkpoint
signal             USR2
when               xs


Similarly for BLCR

 >qconf -sckpt BLCR
ckpt_name          BLCR
interface          APPLICATION-LEVEL
ckpt_command       /home/neeraj/local/sge/ckpt/blcr/blcr_checkpoint.sh 
$job_id \
                   $job_pid $ckpt_dir
migr_command       /home/neeraj/local/sge/ckpt/blcr/blcr_migrate.sh 
$job_id \
                   $job_pid $ckpt_dir
restart_command    NONE
clean_command      /home/neeraj/local/sge/ckpt/blcr/blcr_clean.sh $job_id \
                   $job_pid $ckpt_dir
ckpt_dir           /home/neeraj/checkpoint
signal             NONE
when               xsr


Please help me...
