PETSC v3.24.0

[pedram mahzari]

I attempted to install pflotran, and I get this error:  

#error "Please use PETSc version 3.24.0 or later: 'git checkout v3.24.0' in $PETSC_DIR"

when I checked pflotran_constants.o, it is requested that:

#define VMAJOR 3
#define VMINOR 24
#define VSUBMINOR 0
#if (PETSC_VERSION_MAJOR < VMAJOR ||                    \
     (PETSC_VERSION_MAJOR == VMAJOR &&                  \
      (PETSC_VERSION_MINOR < VMINOR ||                  \
       (PETSC_VERSION_MINOR == VMINOR &&                \
        (PETSC_VERSION_SUBMINOR < VSUBMINOR)))))
#error "Please use PETSc version 3.24.0 or later: 'git checkout v3.24.0' in $PETSC_DIR"

However, it is stated on the website that v3.21.5 should be selected for PETSC. 

When I installed pflotran using v3.24.0, I keep receiving pflotran run crashes if number of cores is above 4 (probably MPI mismatch).

I used git checkout v7.0, and it worked with PETSC v3.21.5

Yes. I need to update the development version of the documentation to reference PETSc 3.24. 

PFLOTRAN v7.x is compatible with PETSc 3.21.x

PFLOTRAN master branch is compatible PETSc 3.24.x
