and I try to compile and run the program
written in the file e.c<br>
<br>
<pre><font color="#0000ff">~# cat e.c
#include <petsc.h>
int main(int argc, char **argv) {
PetscErrorCode ierr;
PetscMPIInt rank;
ierr = PetscInitialize(&argc,&argv,NULL,
"Compute e in parallel with PETSc.\n\n"); if (ierr) return ierr;
ierr = MPI_Comm_rank(PETSC_COMM_WORLD,&rank); CHKERRQ(ierr);
ierr = PetscPrintf(PETSC_COMM_WORLD,"My rank is %d\n",rank); CHKERRQ(ierr);
return PetscFinalize();
}
</font>
</pre>
I compile it with the command<br>
<br>
<pre><font color="#0000ff">~# mpicc -o e e.c -I/usr/include/petsc64 -lpetsc64</font>
</pre>
and I run it with <br>
<br>
<pre><font color="#0000ff">~# mpirun -np 8 ./e</font>
<font color="#0000ff">My rank is 0
My rank is 0
My rank is 0
My rank is 0
My rank is 0
My rank is 0
My rank is 0
My rank is 0</font>
</pre>
but all my process get rank 0.<br>
<br>
Do you know what I'm doing wrong?<br>
<br>
Thank you!!<br>
<br>
Best regards,<br>
