PetscLogGpuFlops

Log how many flops are performed in a calculation on the device

Synopsis

static inline PetscErrorCode PetscLogGpuFlops(PetscLogDouble n)

Input Parameter

• flops - the number of flops

Notes

To limit the chance of integer overflow when multiplying by a constant, represent the constant as a double, not an integer. Use PetscLogFlops(4.0n) not PetscLogFlops(4n)

The values are also added to the total flop count for the MPI rank that is set with PetscLogFlops(); hence the number of flops just on the CPU would be the value from set from PetscLogFlops() minus the value set from PetscLogGpuFlops()

Developer Note

Currently Fortran stub generator cannot run through files in include
