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

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.
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?
