[Nek5000-users] hpts issue: not dumping anything

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

Hi Michael,

I've had some experiences on IBM machines in the past where the
file never appeared unless it was explicitly closed.
Surprisingly, this was the case even if I properly exitted.

I've not looked at the hpts source, but this may be the issue.

Can you try closing the file prior to exitting?

Obviously this is a pain in a situation where you want to
let your run keep going until terminated by the end of
your allocated block, but I wouldn't know anyway around it.

There may be a compiler option to force it to not buffer
the I/O so parsimoniously.

Paul
