Telemac2d Mersey tutorial 14 years 9 months ago #36

:unsure: I ran the Mersey tutorial example for telemac2d in parallel processing mode which failed. Does anybody know why it failed and how to overcome this problem? I attach the log file for the failed run.

Dear hydroenvironmental

The log file is not attached. Could you post it again?
Did you test this example without any change (scalar mode)? If yes, is the result was OK?

Regards
Christophe

Dear Tony (hydroenvironmental),

I found why the mersey telemac2d case does not work in parallel. We are working currently on a new release of the system, v6p0, which will be made available during the summer, in which we had already modified the way the subroutine streamline works. In short, I have now a new version of v5p9, including some of the coming parallelisation changes of v6p0. This latest version of v5p9 now works with the mersey in parallel.

I will shortly make this version available on this web-site.

Best regards,
Sébastien.

That's great :) as I was unsure how to debug this problem look forward to getting the upgraded source code and thanks very much for the very prompt reply to my query

I have installed V5p9R5 as advised but on running the Mersey Example in parallel processing mode it still fails. I have attached the pdf of the error message


Any suggestions??

Tony,

Just to check - can you make sure you deleted the local executable (in the mersy directory) before re-runing telemac2d ...

telemac2d will then re-create a new executable for the mersey, given the new version of the system

Best regards,
Sébastien.
