[Nek5000-users] compilation, large memory

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

Hi Frank,

Are you running in parallel?   How many processors, and how
many elements in the problem of interest?

If you have, say, 120 elements, and are running on 4 processors,
you can set lelt=30, which would reduce your per-processor-memory
footprint by a factor of 4.

Cheers,

Paul

I am having a problem compiling on an x86_64 system.  Smaller problems
work fine.  My SIZE file starts out with:

       parameter (ldim=3)
       parameter (lx1=6*4,ly1=lx1,lz1=lx1,lelt=120,lelv=lelt)
       parameter (lxd=9*4,lyd=lxd,lzd=lxd)
