How to setup Distibuted processing in ADE L

Hi Kirill

Would you please post the contents of your queue_config file?

Thanks
Quek

 Hi Quek

 Of course, here it is

fast 2

nuclon 2

silver 2 

fast is a name of a queue (i've chosen it randomly)

nuclon and silver are names of the of the hosts (silver is main machine)

PS PS i forgot, i try to use LBS manager to distribute simulations

PPS i've started queue manager and have made simulation on slave host, but it doesn't save my time on simulation. And there is an error when i choose list instead of queue (it's said in distproc.pdf that i should type the names of hosts in a row, but error is "the unknown host 'silver nuclon')

Thanks

Hi Kirill

Thanks. I am doing some testing using IC614-501 and is seeing the same error if I do not enable auto job submit option. I will update you again.

Hi Kirill

The error message "queueName should be string type" appears because cdsqmgr has not been properly setup. I saw the same error because I had forgotten to start cdsqmgr before starting Virtuoso. I started cdsqmgr after Virtuoso has started up. Please try this:

a. Exist Virtuoso

b. Start cdsqmgr as follows:
linux>pkill cdsqmgr
linux>cdsqmgr /your-full-path/myQueueFile

c. Start Virtuoso

It should work now. Distributed processing is working for me now.

 Hi Quek

I've tried to run parametric simulation with using DP, but even with only 3 points in analysis much time is taken. For example, without DP it takes about 15 seconds, with DP it takes about 2 minutes (the same simulation is made).

And in the end such message is displayed "Cadence Analog Ditributed Processing option: Job 'job050' failed with exit status = 1

And between points there is a message "function ansCdlCompPrim redefinied" 

Maybe i've done something wrong again? 

PS i found that in terminal there are some errors (wn is a parameter from 20um to 30um with step 5um):

cat: cannot open /home/kruglov/Sim/test_opamp1/spectre/schematic/param/job050/wn=2.5e-05/psf/spectre.out

cat: cannot open /home/kruglov/Sim/test_opamp1/spectre/schematic/param/job050/wn=3e-05/psf/spectre.out
 

So i think that parametric analysis can be done only for one point (beginning point) and can't be done for other points 

Hi Kirill

If you run "adptest" cmd in a terminal window, are there any test items that fail?

linux>adptest

Hi Quek!

silver% adptest

BEGIN Analog Design Environment Distributed Processing Setup Test

Testing for existence of LBS_CLUSTER_MASTER variable...
    PASSED.

    PASSED.

Please be patient - the remaining portion of the test takes some time.

PS there are 3 queues - 1)fast with 2 hosts 2)slow1 with nuclon host 3)slow2 with silver host

So everything is ok as i see.

PPS when i run parametric analysis with 'slow2' queue - everything is OK, but when i run the same analysis with 'slow1' queue - error occurs: Job failed with exit status = 1. And there is an interesting thing - first run of the same parametric analysis with 'fast' queue (both hosts) failed, but the last run was correct. Maybe the problem occurs when i run something on slave host (nuclon)?

Hi Kirill

Sorry for the late reply. I thought that adptest check might reveal some problems with your setup but it looks like everything is ok. Besides "exit statu=1" message, were there any other error/warning messages in ciw or the simulator log files?

I doubt that upgrading to the latest IC614-502 would resolve the problem. This looks network related too. It would be great if you can contact your local Cadence support for more help.
