Hi Barry,
I've put the functions and fortran bindings in the attached files. In our code, we use them as follows:
CALL mpi_bcast(value,1,MPI_LOGICAL,iproc,MPI_COMM_WORLD,ier) IF(ier/=0) CALL tracing_abort('ERROR in bcast logical root !')
IF (iproc==thisprocess) THEN ier = PetscAdminSend(1*(nprocesses-1),MPI_LOGICAL) ELSE ier = PetscAdminRecv(1,MPI_LOGICAL) END IF
I also noted that you changed the treshold from 0.1% to 0.01%, so I tried to change it as a user with PetscLogSetThreshold, but this function seems not accessible to users (and there's no fortran version or manual page).

Hi Barry,
In our version of the nested timers, we had the functions PetscAdminSend, PetscAdminRecv and PetscAdminReduce. So I was expecting to find them at the end of the file petsc-3.8.4/src/sys/logging/xmllogevent.c but apparently you (re)moved them?
I do not remember why I would have removed these functions. If you can send a patch that would return them I would gladly try to get them working with PETSc again.

We basically used these functions to fill the transfer(GiB/s) and reductions/s columns of the log just like we use PetscLogFlops to fill the compute(Mflops) column for our registered events.
How should I do this with the petsc version of the nested timers?
