[petsc-users] MPI_Wtime in fortran

Dear all

In my petsc fortran code, I am using MPI_Wtime to measure times. I include

#include <petsc/finclude/petsc.h90>

When compiling, I get warning for MPI_Wtime

*Warning:* Possible change of value in conversion from REAL(16) to REAL(8)
at (1) [*-Wconversion*]


But MPI_Wtime is supposed to return double precision. The values I get from
this function also seem to be wrong, always zero.

Thanks
praveen
