Greetings - I'm running a Monte Carlo simulation on a server which has 192 GB RAM and 32 processors. When I run the model, I receive the following error:
*** FATAL ERROR THERE IS NOT ENOUGH MEMORY SPACE TO RUN Mplus ON SEVERAL PROCESSORS. SET THE NUMBER OF PROCESSORS TO A SMALLER VALUE.
I'm able to set the process=23 and it will run, but not beyond. There are 9 dimensions of integration with 900 integration points (using integration=montecarlo). Curiously, I installed Mplus and downloaded the upgrade to 6.12, and though the "?" icon says 6.12 combination add-on, the command prompt window says it's 5.1. Could this potentially be contributing to the problem?
Yes this is the problem. You are running a 32-bit executable (version 5.1). Instead you should run the 64-bit executable version 6.12. You have both versions on your computer and are probably just starting the right one. Look in the "Program Files" directory, not "Program Files (x86)".
