[petsc-users] PETSc binary write format

[Sajid Ali]

It's just a cleaner re-write of the petsc output that I can understand
(which I intend to modify from python in the future). I tried removing the
new line characters but that didn't work either.

Looking at the first line of the binary dump from petsc output :

[sajid at xrm <https://lists.mcs.anl.gov/mailman/listinfo/petsc-users>
temp]$ xxd -b vector.dat
0000000: 00000000 00010010 01111011 01001110 00000000 00000000  ..{N..


The first 4 bytes combine to give

*00000000000100100111101101001110*

Which is int-32 representation of VEC_FILE_CLASSID and this is the first
line of my file as well.


Thank You,
