Ocean distributed simulation problem

$

Hi 

I try to run an ocean script with distributed simulation 

I use SGE (LBS_BASE_SYSTEM=LBS_SGE) - cadence version : IC6.1.7-64b.500.15

I don't have any problem with jobs distribution. The netlist is well created only for the first job and not for the others.

For example In result directory /scratch/test/spectre/config/distributed/job_2017/netlist, the input.scs file is not created.

error messages :

--virtuoso message 1 for each job ------------------------------------------------------------------------------ 

Delete psf data in /scratch/test/spectre/config/distributed/job_2017/psf.

submitting job...

INFO (50) : Although ADE failed to generate a valid netlist, but still a dummy job is being submitted.

In lack of a valid netlist, the job will fail almost instantly without consuming too much machine resources

or processing time but will help in deletion of temporary data and reusing the job name for the next run.

-----virtuoso message 2 for each job-------------------------------------------------------------------------

Cadence® Analog Distributed Processing option: Job `job_1017' failed with exit status = 1

-------------------------------------------------------------------------------

spectre.out error in job_xxx/psf directory

Error found by spectre.
ERROR (CMI-2011): Unable to open input file `input.scs'.
No such file or directory.

---------------------------------------------------------------------------------

Someone can help me with this problem ?

NB: the same kind of script worked with a previous cadence version  IC6.1.5.500.6 

Best regards

Script :

----------------------------

simulator( 'spectre )
hostMode( 'distributed )

design( "/scratch/test/spectre/config/netlist/netlist")
resultsDir( "/scratch/test/spectre/config" )

envOption( 'cmd64bit t
)

analysis('tran ?stop 2u )
saveOption( 'save "selected" )

vsig=2.0

initialize jobList to nil
jobList = nil

for(i 1 5

sprintf(vsig_txt "%g" vsig)
desVar( "VSIG" vsig_txt)

sprintf(Nom_job "job_%d" i)

jobList = append1( jobList run(?jobName Nom_job ))

;next step

vsig=vsig-0.2

)

; wait for the jobs to finish

wait( (append1 jobList nil) )
