[petsc-users] MPI_Wtime in fortran

[Praveen C]

To be more precise, my code looks something like this

implicit none
#include <petsc/finclude/petsc.h90>
double precision time

time = MPI_Wtime()

I get the warning of conversion from REAL(16) to REAL(8) and the value of
time is always zero.

Thanks
praveen
