I guess PETSC_SCALAR should be correctly defined for the case complex+__float128 in petscsys.h. Maybe a new PetscDataType PETSC___COMPLEX128? This would require changing PetscMPIDataTypeToPetscDataType and then PetscBinaryRead...

It is not necessary, I can write a kind of convertor myself. Otherwise complex128 seems to be working. -- Regards, Alexander
