Dear PETSc team.

This CD is sent in response to a communication between myself and the
PETSc team via the petsc-users mailing list.

I have recently installed PETSc v2.3.1 and have discovered that it fails
to solve certain problems when using Spooles. These problems were being
solved successfully when using PETSc v2.3.0. I am using Spooles
downloaded from the the PETSc ftp site and built into
PETSC_DIR/externalpackages.

Included on this CD is an example of one of the problems that fail to
solve. "mat" and "rhs" are the matrix and RHS in binary format as
generated by MatView() and VecView() respectively.

Would you kindly investigate this and see whether or not you replicate
the results I have been getting.

Kindest Regards

Mr Stephen R. Ball
