[torqueusers] Abaqus with PBS

Hi Josh,

It is my experience that the compute nodes MUST be able to access the license server. We have set up NAT on the master nodes. (if you don't know NAT does some fancy things which allow a private network to talk to a public network). We have many software packages which use licence servers, and this is the only method I know of apart from installing the license server on the master node.

Hope this helps,

  Hi Ashley,

  Thanks for the info. We still unable to get the abaqus to work, I believe the problem is due to the compute nodes (Slave nodes) not be able to access to the license server directly. Only Master node able to access to the license server. Our clusters also have shared file system, Abaqus is installed in there and available for all nodes. Do I need to configure other things/environmet instead of "abaqus_v6.env"? I'm attached the following error from the abaqus output. 

  Server node is down or not responding
  See the system adminstrator about starting the server, or
   make sure the you're referring to the right host (see LM_LICENSE_FILE)
  Feature:       explicit
  Hostname:      cluster 
  License path:  27001 at cluster
  FLEXlm error:  -96,482
  For further information, refer to the ABAQUS Installation and Licensing Guide,
  or contact your ABAQUS Inc. representative. 

  Pls let me know if you have an idea to fix this. Thank you for your time. :-)

  Best Regards,

    Hi Josh,

    I set up Abaqus (6.5-4) on our cluster last week. The first thing is the
    nodes in our cluster have a shared file system, we use for software 
    packages (for us this is called /pkg). Abaqus is installed here and so
    is available on all the nodes. We also have NAT setup on the master
    nodes so that Abaqus can access the license server (which is on another

    Assuming this is set up you need to create a site file 'abaqus_v6.env'
    most of the directives are specified in the manual but here are the
    important one for torque:

    #Set up your MPI environment, this is for LAM which we use at QUT. 
    #We also use ssh instead of rsh.
    mp_mpi_implementation = LAM
    mp_mpirun_path = {LAM:'/usr/local/bin/mpiexec',
                     MPICHGM:'/usr/local/mpichgm- 1.2.6..14a/bin/mpirun.ch_gm'}
    mp_mpirun_options = '-boot'
    #mp_rsh_command = 'rsh -n -l %U %H %C'
    mp_rsh_command = 'ssh -x -n -l %U %H %C'

    #this is the location of the license server
    abaquslm_license_file=" 1712 at sirius.qut.edu.au"


    # QUT batch queue setup; abaqus_2cpus is the default queue 
    # (Using bash as the PBS interpreter is better than tcsh - fewer probs!)
    run_mode = BATCH
    scratch  = "/tmp"


    queue_cmd="qsub -r n -q abaqus_nolimit -S /bin/bash -V -l nodes=1:ppn=2 %S"
    abaqus_2cpus="qsub -r n -q abaqus_nolimit -S /bin/bash -V -l
    nodes=1:ppn=2 %S"
    abaqus_4cpus="qsub -r n -q abaqus_nolimit -S /bin/bash -V -l 
    nodes=2:ppn=2 %S"
    abaqus_8cpus="qsub -r n -q abaqus_nolimit -S /bin/bash -V -l
    nodes=4:ppn=2 %S"

    Using this setup the user submits a job (from the master node) like so:
       'abaqus job=pillar queue=abaqus_8cpus cpus=8' 

    I hope this helps,
