Questions about OCEAN XL

jorankin

Stacy,

    Hello. I am writing with regards to OceanXL. I, too, am having trouble using OceanXL to do what I have been able to do previously with Ocean. My two issues are below:

 1. I would like to have OceanXL output only certain outputs (such as those I have specified in ADE or ADEXL, like gain, bandwidth, etc) in tabular format using something like fprintf or the like. It doesn't seem to work the same way I have tried in the regular OCEAN since I am running distributed sims.

 

2. I would also like to run OCEANXL in distributed mode AND run it in the background without it holding down my cadence session. In the past, I have run OCEAN using the icsub command, but this precludes me running distributed sims. I would like to run OCEANXL using the icsub command AND have it use my distributed simulation settings specified in my OCEANXL script.

      Of course, I can run distributed sims in ADEXL which works. But when I run enough sims in parallel, my cadence session gets tied down and I can't do anything else. This is undesirable. My productivity goes down 10x!

     The above issues are not spelled out at all in the OCEANXL reference provided to designers. Do you have suggestions for a better reference and/or how to fix the problems?

 

Thanks,

John

  • Andrew,

        I appreciate your response on this. I should have made a new post in the first place, but I'm a newbie to this forum and pretty much forums in general.

          It looks like I've figured out how to run an OCEAN that includes OCEANXL distributed processing settings. To get this to work, I simply have to submit the job to the same queue that the distributed processing commands within the OCEAN (XL) script specify. For example, if, in my script, I specify:

    ocnxlJobSetup( '(
            "blockemail" "1"
            "configuretimeout" "300"
            "distributionmethod" "LBS"
            "jobqueue" "medium"
    ...

    Then I should submit the command as follows:

    bsub -q medium "ocean <ocean script.ocn> outputlog.log"

    This seems to work well for me.

          I have also found that if I run these simulations in OCEAN (XL) and close the corresponding ADEXL session, importing the data into ADEXL doens't take nearly as much time to process the data as it did before when I ran the simulation interactively in ADEXL. So, I could postprocess using the axlWriteDatasheet function, but ADEXL will work too. I will still look into this datasheet function.

        I have another question that I will post in another thread.

        You are right about the company I work for. I am new as of April and that's why I didn't know much about bsub or icsub...

     Thanks,

    John
