APS or IRUN multithread = multicore?

greatqs

Is the terminology of "multithread" (i.e. +mt = x) in APS/IRUN means number of CPU core to use? On a 12 cpu core machines, the max number of "multithread" should be 12, is it right? Thanks

    Hi all,

    Sorry to up this topic.

    Just to explain me why, when i want to do an APS simulation with multi threads option, i cannot use the maximum specified.

    For example, when I set 6 threads, the message in start of simulation is: 

    "Multithreading Enabled: 6 threads on system with 8 available processors."

    and after:

    " Waiting for available license for Virtuoso(R) Spectre."

    And the simulation doesn't start, I've to change the 6 to 4 and then the simulation start.

    But normally I can use 8 no ? 

    Note that, no simulations are running (even from my colleague) when iḿ doing these tests.

    Thanks in advance for your help.

    Rgds,
