Sorry this is my 2nd email. See below for the 1st email.
Using petsc.h90 gave the error "... segmentation

My impression was intel is mostly faster. However, does it apply to
gfortran too? Is it also faster for a lot of code than Intel
fortran? I'll give it a go if it's so. However, I remember changing
a no. of options to build and in the end, it was slower. that's a
few yrs ago though.<br></div></blockquote><div><br></div><div>Anything is faster than a seg-faulting compiler. However, we have just run a number of tests in which</div><div>gcc was faster.</div><div><br></div><div> Matt</div>

<br>
I encountered the error below when
compiling my code using intel fortran:<br>
<br>
/tmp/ifortlPEDlK.i90: catastrophic
error: **Internal compiler error:
segmentation violation signal raised**
Please report this error along with the
circumstances in which it occurred in a
Software Problem Report. Note: File and
line given may not be explicit cause of
this error.<br>
<br>
In the end, I realised that it is due to
using <b>petsc.h90</b>:<br>
<br>
module PETSc_solvers<br>
<br>
use set_matrix<br>
<br>
...<br>
<br>
implicit none<br>
<br>
contains<br>
<br>
subroutine
semi_momentum_simple_xyz(du,dv,dw)<br>
<br>
<b>#include "finclude/petsc.h90"</b><br>
<br>
integer :: i,j,k,ijk,ierr,II !,ro...<br>
<br>
If I use :<br>
<br>
<b>#include "finclude/petsc.h"<br>
<br>
or<br>
</b><br>
<b>#include "finclude/petscdmda.h90"</b><br>
<b>#include "finclude/petscksp.h90"</b><br>
<br>
Then there is no problem.<br>
<br>
May I know why this is happening?<br>
<br>
Although I can now compile and build
successfully, is this the right way to
go?<span><font color="#888888"><br>
