Not out of the box no. There is -info ::self which makes info only print from calls made on PETSC_COMM_SELF, but I don’t think that’s what you want. Best advice would be to print to a file and grep the file for any lines starting with the rank number you want. Best regards, Jacob Faibussowitsch (Jacob Fai - booss - oh - vitch)

Can I make -info only print from one process? Mark
