That’s C notation for a type cast.

what does this do:
long id = (long) t;

why is the second ‘long’ in brackets?

Very Interesting example

Thanks for the clarification. I’ve removed mention of multiple cores from the post title and text.

Hi Ashish,

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.

This is good about multithreading using pthread but can you suggest how to assign various threads in each core manually through any APIs please tell

Maybe I’m missing something. Are you implying that multiple cores aren’t getting used in this code? Where is the speedup coming from then?

Fully agree with what Siddhartha has pointed out. Where is code that specifies using multiple cores?

Great guide, thanks for posting.

Because I ssh into several different servers with generic usernames (e.g. login01), I found it more useful to use the other part of the hostname rather than the first field.

I used the following command to obtain this:

host=`echo $(hostname) | sed “s/$(echo “$(hostname -s)\.”)//g”`

to obtain “ls4.tacc.utexas.edu” instead of “login2″ from “login2.ls4.tacc.utexas.edu”

I did not see any multi-core specific code in the example. The sample code seems to illustrate standard pthread API usage. Did I miss out something ?

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