Increase memory size when using MaxFlex

Hamed Hani
Hi,
 
I am trying to run Adams MaxFlex on an HPC. I run to a memory error with the following message:
 
Severity is 'USER FATAL MESSAGE' (1)
%1: 'because BUFFPOOL size exceeds MEMORY.'
%2: 'MEMORY= 20971520 words, BUFFPOOL= 58889 * (BUFFSIZE+10) = 3859997283 words, BUFFSIZE= 65537 words'
%3: 'Decrease BUFFPOOL or increase MEMORY.'
USER ACTION: Please contact your MSC representative.
 
The platform that I am using is Linux. Is there a way to increase the memory size before running the simulation using environment variables or any other way to resolve this issue without having access to the GUI?
 
Thanks,
Hamed

    I haven't used MaxFlex on the HPC, yet, but A/Solver and A/Car.
    If ANY background-mode start is required, this only works in v2023.3 and newer.
    So first advice would be to use the latest version 2023.4
     
    BTW: "On the cloud" rings a bell as we never got ADAMS 2022+ & RH8 working on virtual clients. (2021.2 and RH7 was half way working, though)
    Do yourself a favor and use a physical hardware on your side of the desk.
     
    If it's just the memory setting, that's easily done:
    Modify your HPC scripts that a directory ~/.msca is created on the HPC node.
    Then create a file named msca_2023.4.reg with this content:
    [MSCA/ASolver/Preferences]
    memSize=huge
     
    Then try again.
