ran out of memory in OpenSeesSP

Post by Luisa »

Hi, When run out of memory (even if you use: system Mumps -ICNTL14 20) can we try something like this: system Mumps -ICNTL14 80? If not, what should I do then? Thank you.

As far as I know, you can use INCTL14 80 or larger, remember using OpenSees 64 bit. Have you checked whether there is a memory leak in your model or not?

Thank you mo_zarrin. Maybe the problem is that my laptop is a 6 GB RAM one! It doesn't work even with "INCTL14 100"! Nonetheless, the problem may source from something else!
Could you tell me please, are the only differences between regular OS and OpenSeesSP tcl files that:
1- we just simply change the system for analysis in OpenSeesSP (system Mumps -ICNTL14 100), and
2- we use -xml instead of -file in node/element recorders.
Or should I alter anything else in my tcl file as well?! Thanks.

the Mumps _ICNTL 100 is going to fail if you are having memory problems as that is requesting an NxN matrix (do the math: N X N X sizeof(double) is how much memory you need).

you don't need -xml

I've changed the system (64-Gb RAM) and it seems there is no problem with memory anymore. However, when I run OpenSeesSP I get the following error:

Could you tell me what the reason is?!

Thanks for your reply Dr McKenna ... The system is Mumps and here are the analysis commands:

constraints Lagrange;
numberer RCM;
system Mumps -ICNTL14 80;
test EnergyIncr 1.E-6 10;
algorithm Newton;
integrator Newmark $gamma $beta;
analysis Transient;
analyze 500 0.01;

is this by any chance occuring on a second analysis and working for the first.

I tested some other systems and still get the same error! Is there any solution? Why this happens again and again ... ?! Is the problem with the Mumps?

So ... isn't it possible to solve the mumps problem?! Should I forget about parallel processing?!
