Hello all!
At present time I need to compile solver called Defmod (https://bitbucket.org/stali/defmod/wiki/Home), which is written in Fortran 95.
Defmod uses PETSc for solving linear algebra system.
Defmod uses PETSc for solving linear algebra system.
Solver compilation with 32-bit version of PETSc does not cause any problem.
But solver compilation with 64-bit version of PETSc produces an error with size of ierr PETSc variable.
But solver compilation with 64-bit version of PETSc produces an error with size of ierr PETSc variable.
1. For example, consider the following statements written in Fortran:
PetscErrorCode :: ierr_m
PetscInt :: ierr
...
...
...
call VecDuplicate(Vec_U,Vec_Um,ierr)
call VecCopy(Vec_U,Vec_Um,ierr)
call VecGetLocalSize(Vec_U,j,ierr)
call VecGetOwnershipRange(Vec_U,j1,j2,ierr_m)
As can be seen first three subroutunes require ierr to be size of INTEGER(8), while the last subroutine (VecGetOwnershipRange) requires ierr to be size of INTEGER(4).
Using the same integer format gives an error:
Using the same integer format gives an error:
There is no specific subroutine for the generic ‘vecgetownershiprange’ at (1)
2. Another example is:
call MatAssemblyBegin(Mat_K,Mat_Final_Assembly,ierr)
CHKERRA(ierr)
call MatAssemblyEnd(Mat_K,Mat_Final_Assembly,ierr)
I am not able to define an appropriate size if ierr in CHKERRA(ierr). If I choose INTEGER(8), the error "Type mismatch in argument ‘ierr’ at (1); passed INTEGER(8) to INTEGER(4)" occurs.
If I define ierr as INTEGER(4), the error "Type mismatch in argument ‘ierr’ at (1); passed INTEGER(4) to INTEGER(8)" appears.
If I define ierr as INTEGER(4), the error "Type mismatch in argument ‘ierr’ at (1); passed INTEGER(4) to INTEGER(8)" appears.
3. If I change the sizes of ierr vaiables as error messages require, the compilation completed successfully, but an error occurs when calculating the RHS vector with following message:
[0]PETSC ERROR: Out of range index value -4 cannot be negative
