What do you do to increase the amount of available memory?
<div><br>
</div>
<div>In your current setting, Nek5000 compiles with one processor since lpmin is set to 1. You have to increase it to successfully compile.</div>

<div>Hi all,<br>
<br>
</div>
I'm trying to compile a 3D mesh with mesh size of 6000 ekements. Unfortunately I keep running into compilation errors. To be clear I can compile problems upto 3000 elements large. But setting lelt value larger than 3000 results in an error.
<br>
<br>
</div>
I have realised this might be a memory issue and have tried to compile with increasing amounts of available memory. This does not seem to resolve the issue.<br>
<br>
</div>
To be clear my SIZE looks like this<br>
<br>
parameter (ldim=3) ! domain dimension (2 or 3)<br>
parameter (lx1=6) ! p-order (avoid uneven and values <6)<br>
parameter (lxd=10) ! p-order for over-integration (dealiasing)
<br>
parameter (lx2=lx1-2) ! p-order for pressure (lx1 or lx1-2)<br>
<br>
parameter (lelg=6000) ! max total number of elements<br>
parameter (lpmin=1) ! min MPI ranks<br>
parameter (lpmax=1024) ! max MPI ranks<br>
parameter (ldimt=1) ! max auxiliary fields (temperature + scalars)<br>
<br>
</div>
Sincerely,<br>
<div><br>
