[petsc-users] Is PETSc using internet?

[Eda Oktay]

Hi all,

I am using the following libraries and for some reason, I figured out
that if ı am disconnected to internet, my program is not working:

#include <petscmat.h>

#include <petscis.h>

#include <petscsys.h>

#include <slepceps.h>

#include <stdio.h>

#include <stdlib.h>

#include <petsctime.h>

#include <petscdraw.h>

#include <petscviewer.h>

#include <petscdm.h>

#include <petscdmlabel.h>

#include <petscds.h>

#include <petscsf.h>

#include <mpi.h>

#include <math.h>

#include <float.h>

#include <string.h>

#include <time.h>

I thought that there is no reason for PETSc to go online for libraries
but I couldn't find any other reason.

The first thing I am doing in my program after initializing SLEPc and
PETSc is reading the binary matrix from my file and when I am offline,
the program can't even get the matrix.

Thanks,

Eda
