How do you utilise your computer to reduce Run Time?

Hello,

I am running a non-linear Opti-struct model with an average run-time of 4.5 hours (non-linear due to the need for SLIDE contacts).

I was hoping that by running it on a more powerful machine that I could reduce the run-time but I've only managed to knock 10mins off. I feel like I must have missed something.

These are the detail of the computer I'm trying to run on:

Intel(R) Xeon(R) Gold 6242R CPU @ 3.10GHz   3.09 GHz  (2 processors)

256 GB (256 GB usable)

64-bit operating system, x64-based processor

I have been submitting my runs with these options. 

-len 80000 -optskip -nt 6

Could any one give me any pointers as to what I am missing?

Thanks

Alice

    Run options can be found here:  https://2021.help.altair.com/2021/hwsolvers/os/topics/solvers/os/run_options_os_r.htm

     

    Since you have two processors, you should be able to use both of them using the "-np 2" option.

     

    Does your .out file give any warnings for memory usage?

    If you are into reducing computation time in general , you can check the number of iterations at the end of the *.out file and the *.stat file. The stat files is not very "verbose" / "designed to be comprehensive" but you can take a look at it and see what parts of the computation process take more time.
