[petsc-users] Loading DM binary data into 64-bit-integer PETSc

[Barry Smith]

  In general, no because the integer values inside the files will have different lengths. You can use the Python lib/petsc/bin/PetscBinaryIO.py or MATLAB share/petsc/matlab/*.m utilities to read the data from one format and save it in the other. Sorry for the inconvenience.
