running simulation is very slow

    Hello
    when i am trying to run simulation several times from a script file
    using the lines:
    schCheck
    (saveOption( 'subcktprobelvl "1"
    ( saveOption( 'currents "all"
    ( saveOption( 'save "all"
    ()run
    for each time it takes about a minute or so to the simulation to
    initiate and then run.
    why is that and what can be done?
    thanks

  2. Are you running any kind of load sharing in the background?

    I dont think so, what do you mean by load sharing?

  4. Do you run some kind of cluster server client like LSF from Platform
    Computing where you use a command to send your actual command to the
    dispatcher for execution in a computing grid. This feature is often
    used to pool computers and assign priorities to queues etc. so that
    you don't need a supercomputer per employee. The dispatching job may
    be implemented so that it is totally transparent to the user so you
    maybe have to ask your design support.

    If you have something like LSF, then you may be using the wrong queue,
    wrong parameters, have been starting too many jobs last week etc.
    There are many things that Design Support can do to balance the load
    of a grid. Most likely by giving the most active users a penalty like
    having to wait a minute for the simulation to be dispatched.
