[Nek5000-users] Limits on Buffer for Writing Binary Data

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

Neks,

I have been working on routines to dump out interpolated data from Nek to
binary files that can be read in VisIt.  The data I'm outputting is
designed to cover any subdomain inside the simulation and at any resolution
(typically much higher than Nelm*lx1^3).  I have found that when I try to
dump too much data at once through a modified version of out_buff() and
byte_write() it can cause an error and kill my program.

I am assuming there must be some sort of buffer limit on how much data can
be written at once, but I haven't been able to determine what it is
specifically.  It seems to be a function of lx1 and lelt though.

Anyone know what the limit is/what is causing this error?

Thanks,
