--- Comment #9 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-06-28 12:20:41 UTC --- (In reply to comment #8) > do you have some specific (and certain) recommendations in order to make this > scientific code to be compiled (alongside with a lot other fortran scientific > code)? As short term solution: Use an older version of gfortran (before 4.6.0-2010-05-05) - or remove the 0 initialization. While the Fortran standard does not guarantee it, in practice, static memory should nevertheless be zero initialized (.bss). The proper fix will take a bit longer: A couple of days for the fix and then it will likely also take a while until a Red Hat/Fedora build will be available. (Though, non-Fedora nightly builds will have it earlier.) * * * (In reply to comment #7) > As written, I think it should be sufficient to support the initialization > via a scalar. For what it is worth: Intel's compiler seem to do the same. Hence, DATA B/<repeat>*<value>/ is is very fast while using DATA B(:)/<repeat>*<value>/ is very slow - even though, both lines are effectively the same.
