Reading error in validation procedure (bumpflu) 13 years 9 months ago #1112

Dear all,

We have compiled Telemac on linux with gfortran. It works quite well but we have a problem with the validation procedure.

We have done the bumpflu test case and we get the following error:

We have also tested to validate two output files of the same run obtained on the same computer and we get the same error !!!!!

If someone have a solution concerning this problem we are interested in.

Hello Julien,

We already had this problem recently with a new version of Intel compiler on Linux. It could be we have a weakness in subroutine suite_serafin.f in library BIEF. In fact the file is read once to get the number of records correctly written. Then there is a REWIND to read it again. It is after that REWIND that there is an error when reading the title again (in subroutine skipgeo.f). So it is like the REWIND does not work.
However installations of gfortran do work on Linux, so it can probably be solved by a compiler option.
We still look for a possible solution and keep you posted.

Regards,

Jean-Michel

We have compiled TELEMAC with gfortran on Ubuntu (one of our vritual computer for automated validtaion of the system). We do not seem to have this problem. The bumpflu test case also works in parallel.

If it helps, here are the three command line options:

Creating obejcts:
gfortran -c -O3 -ffixed-line-length-132 -fconvert=big-endian -frecord-marker=4 ...
Creating libs:
ar cru ...
Creating executables:
gfortran -fconvert=big-endian -frecord-marker=4 -v -lm -lz -o ....

For the parallel verison you need to add the -lpthread to the executable commande.

Hope this helps.
Sébastien.

jchauchat	Hello We were able to reproduce the problem with the release v6p1 and the same compiler (gfortran 4.1.2). After upgrading the compiler to version 4.4.6 the reading problem of selafin files has been corrected. So if you encounter this problem look at your gfortran compiler version J. CHAUCHAT
