Re: [Boost-users] Threads example question

What am I doing wrong?

boost::timer doesn't tell you the elapsed wall-time necessarily. On linux, it gives elapsed cpu time (which adds together the processing time used by all processors).

Thanks, this is it. I tried clock() from time.h and it works similarly to timer. time() from time.h seems to give me wall-time, but only with 1s resolution. here: http://pastebin.ca/1473138 With four calls to the same function, I'm now getting the speedup I was expecting: 1cpu 18s 2cpus 9s 3cpus 9s 4cpus 5s AW
