When using fractional progress reporting, TPIE is able to measure and remember the proportion of execution time spent between the fractions.
The TPIE Hello world example program writes, sorts and verifies a stream of numbers. In the source code we do not have to specify how much time writing takes compared to sorting. Instead, we keep track of this information in an auxiliary file.
If helloworld
is compiled without the NO_FRACTION_STATS
define, upon exiting, the program will write the fraction database to a file named fractiondb.gen.inl
. When compiled with the NO_FRACTION_STATS
define, this file is included in the source code.
The following example is from the main
function in helloworld.cpp
. For load_fractions
and save_fractions
, include fractional_progress.h
.
