[CIG-SEISMO] Some problems with xspecfem3D and the Intel compilers

[Malladi, Rama Kishan V]

Hi Dimitri, All,
I will check what changed in the recent version of the Intel compiler and see if this can be reported to the compiler team as a bug report.

Thanks

Hi Carène and Fabien, Hi all,

Thanks a lot! Since several users have reported problems with this Intel compiler option, in particular with ifort version 17, let me keep it but turn it off by default (in 2D, 3D, and 3D_GLOBE).

When it works fine it does speed up I/Os significantly though, thus worth trying it. I will mention that in the users manual (of 2D, 3D, and 3D_GLOBE).

Thanks!
Best regards,
Dimitri.
