[Nek5000-users] How to read NEK data generated on another machine (with different endianness)

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

Dear Paul,


Thanks a lot for your prompt response.


I am attaching the error and output files for the job, which did not work. Could you please have a look into it, and suggest something?


When we restart on Juqueen, everything works fine.


Moreover, we are using version 1.0rc1 / SVN r1115 on SuperMUC, whereas 1.0rc1 / SVN r1088 on Juqueen. I don't know, but might this be causing some problem?


Thanks and best regards,

Ambrish

Dear Ambrish,


Nek5000 supports either endian conditions and one

can in principle go back and forth.


What does the error look like?


I'm assuming that the issue does not arise when you

restart on juqueen?


Paul



With best regards,
Ambrish

Dear All,


We have generated some data on JUQUEEN (Julich Supercomputing Centre), and want to analyze them on SuperMUC (Leibniz Supercomputing Centre). But NEK (1.0rc1 / SVN  r1115) on SuperMUC can't process the data. It is giving some error after reading the file.


Original data is in big endian format, and SuperMUC generates data with little endian format. Could this be a problem? If so, how can we tackle this issue?


Thanks,

With best regards,
Ambrish
