long id = (long) t;

why is the second ‘long’ in brackets?

Very Interesting example

speedup is coming from the fact that threads get scheduled and in serial case its just function call. Try to print the cpuid. You will know. This program is just a example of pthread and it will run perfectly on uniprocessor.

Are you implying that multiple cores aren’t getting used in this code? Where is the speedup coming from then?

The sample code seems to illustrate standard pthread API usage. Did I miss out something ?

I plan to use this code as a good example to teach introduction to pthread and multicore programming.

I was mostly interested in using pthreads to do a comparison of how much easier OCaml solutions are.
