Hi,

I managed to find the error appearing after using PETSc 64bit in linux -

call MPI_COMM_SIZE(MPI_COMM_WORLD, num_procs, ierr)

I have assigned num_procs as PetscInt and I got 0 instead of 1 (for 1 procs)

Assigning num_procs as integer as the problem.

Is this supposed to be the case? Or is it a bug?

Thank you very much.

Yours sincerely,

Hi,

I found that I am unable to read in values thru namelist in Fortran after using 
PETSc 64bit in linux.

I have a parameter txt file which is read in using namelist in Fortran:

namelist /body_input/ no_body, convex_body, motion_type, hover, wing_config  ...

open (unit = 44 , FILE = "ibm3d_input.txt" , status = "old", iostat = 
openstatus(4))

         if (openstatus(4) > 0) then

             print *, "ibm3d_input file not present or wrong filename."

             stop

         end if

         read (44,nml = solver_input)

         read (44,nml = grid_input)

         read (44,nml = body_input)...


After using PETSc 64bit, my code aborts and I realise that it is because the 
values have became NaN. Strangely, it does not occur in windows with VS2008.

I wonder if it's a bug with the Intel Fortran compiler 2018.

Anyone has similar experience?
