[petsc-users] ex44f.F90 with fortran data types running with 2 cores

[Yaakoub El Khamra]

I am going over ex44f.F90 with petsc-3.4.2 built with fortran data types
and compiled with intel compilers. Minor code modifications were made:
type(Vec) as opposed to Vec and so on. I also added CHKERRQ(ierr) wherever
it needed to go and increased the DMDA size (I used 32).

The ierr value at the KSPSolve was 78, and stdout had the error message
below. I must be doing something wrong. Anyone has any thoughts on what
that might be?
