After years of procrastination, I've finally put together the CPU timer
I've always wanted. It provides wall-clock time, user CPU time, and
system CPU time. A time reporter class handles the details of display.
Typical output would be:
wall 0.50 s, user 0.03 s, system 0.05 s, total cpu 0.08 s, 15.6%
The percentage is CPU utilization relative to wall clock.
Note that I see a CPU timer as complementary rather than competitive to
the high-precision timer component others are working on. I'm all for
their effort to continue.
My plan is to submit the CPU timer stuff as part of a Boost.System
library, which packages small operating system dependent components
together for convenience.
There is an early version of Boost.System stuff in the vault. Go to the
System directory at http://boost-consulting.com/vault/ to download
The preliminary CPU timer docs can be viewed online at
Note that I did use Boost.Date_Time components. That was because I'm not
very familiar with Boost.Date_Time, and wanted to initially concentrate
on getting the desired results. Advice on how to best make use of
Boost.Date_Time would be appreciated.
Likewise, any other comments are welcome.
