Thanks for your help; both of these worked... Last real machine I
ran on was a Cray YMP, so I'm learning a lot about MPI. I ended
up installing MPI on an SMP machine; compiled NEK for MPI with the
wrappers; and ran it on multiple cores. I assume not quite as
good as OpenMP, but worked great for my purposes...<br>
<br>
Thanks,<br>

Hi Murph,<br>
<br>
A couple of options here:<br>
<br>
1) Try recompiling with G = "-mcmodel=medium" in makenek.<br>
<br>
2) Use more than one core so that lelt can remain the same<br>
but lelg can be as large as lelt*P, where P is the number<br>
of cores you'd like to use.<br>
<br>
Raw email is the standard interface as far as I know...<br>

Hi All,<br>
<br>
Trying to run some initial test cases of a problems I'm
working on:<br>
- Currently on single node (SMP Linux)<br>
- MPI turned off (IFMPI="false")<br>
- DOF at 5 (lx1=6, lxd=9, lelx=8)<br>
<br>
If I run with lp=1,lelt=2160, lelg=2160, for a 12x12x15
mesh, it compiles and runs fine.<br>
<br>
If I up it to lp=1,lelt=4500,lelg=4500, for a 15x15x20
mesh, it crashes the compile with:<br>

<br>
Just wondering if this is due to a true limit with the
platform/word size, or if I'm screwing something up...<br>
<br>
Thanks,<br>
Murph<br>

PS - Is there any other interface to this list other than
raw email?<br>
