[Nek5000-users] Compilation error

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

Hi,

You don't have enough memory on your system for
the per-processor resources required.

Depending on compiler/processor, adding

G="-mcmodel=medium"

might resolve this, particularly if you are on a 64-bit
architecture.

If you are running in parallel it's certain that you
can reduce LELT and then just use a correspondingly
higher processor count.

Note that per-node (per core) memory scales roughly as

     M*(lx1*ly1*lz1*lelt)*8 bytes

where M ~ 300

As an example, if your problem requires 4000 elements and you have
16 processors, it is sufficient to set LELT > (4000/16 - 1) = 249.

hth,

Paul
