[Nek5000-users] how to choose lx1

[nek5000-users at lists.mcs.anl.gov]

Hi Justin,

Thanks for your quick email.

I killed the simulation after half an hour later, because it was still 
on the same line.
I don't think my setup is that big. So I am not sure if I should wait 
more or not.

Best,
Mehmet

Hi Mehmet,

How long is nek at the gs_setup line? It can take several minutes for large
cases.

The last error you're having is because you've run out of memory. Remember
that the memory footprint on each processor scales as lx1^3 * lelt. With
certain compilers you can add the following option in makenek:

G="-mcmodel=medium"

This allows you compile larger arrays, and generally use more memory.

Best,
Justin
