[Nek5000-users] Question - SIZE Parameters And Compilation Errors

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

Hi Murph,

A couple of options here:

1) Try recompiling with  G = "-mcmodel=medium" in makenek.

2) Use more than one core so that lelt can remain the same
    but lelg can be as large as lelt*P, where P is the number
    of cores you'd like to use.

Raw email is the standard interface as far as I know...

hth,

Paul
