Hi, I need to report progress (0-100%, which I compute myself) of my Petsc solver code to an external driver code that is controlling my solver. I had a look at the many Petsc logging functions and examples but I am still not sure which way to go. I tried PetscLogStage, but it does not seem to display any information during the execution, and I also do not see a way this information could be sent somewhere and accessed by e.g. registering a custom (static) function used to inform the downstream code what the solver is doing at the moment. The most trivial solution that I have found is to output a message like [STATUS 50%], which could be intercepted in the downstream code by overwriting PetscVFPrintf, but it sounds rather inelegant. I would be very glad to receive some pointers where to start looking.
Regards, Dominik
