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 system-0.1.zip. The preliminary CPU timer docs can be viewed online at http://mysite.verizon.net/beman/cpu_timer.html. 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. --Beman
