Parallel Processing in win32

[serkan]

Hi,
I am new to the forum. I am doing some kind of C++ programming. which is win32 console application in a .NET IDE. Actually I had 10 different objects they call a particular function to accomplish their task. for eg
 

MyObject1 *obj1 = new MyObject1();<br /> obj1->dosomething();<br /> <br /> MyObject2 *obj2 = new MyObject2();<br /> obj2->dosomething();<br /> <br /> MyObject3 *obj3 = new MyObject3();<br /> obj3->dosomething();

1 2 3 4 5 6 7 8

MyObject1 *obj1 = new MyObject1();<br /> obj1->dosomething();<br /> <br /> MyObject2 *obj2 = new MyObject2();<br /> obj2->dosomething();<br /> <br /> MyObject3 *obj3 = new MyObject3();<br /> obj3->dosomething();

what happens the dosomethings() function is called sequencially and done one after another and takes 10 second. Can I reduce the time by making use of threads. How to know about threads as beginner. Any site which is useful as a tutorial for me.
 
Please suggest
thanks

You can do but code should be parallel. Here function is same,That’s fine. But No variables b/w  those call should not be shared.

Example: Parallel programming using By OpenMP API

#pragma omp sections num_threads(3)<br /> {<br />   #pragma omp section<br />    { <br />         Fun1();<br />    }<br />      #pragma omp section<br />    { <br />         Fun2();<br />    }<br />     #pragma omp section<br />    { <br />         Fun3();<br />    }<br /> }<br /> <br />

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

#pragma omp sections num_threads(3)<br /> {<br />   #pragma omp section<br />    { <br />         Fun1();<br />    }<br />      #pragma omp section<br />    { <br />         Fun2();<br />    }<br />     #pragma omp section<br />    { <br />         Fun3();<br />    }<br /> }<br /> <br />

Then Here three threads execute parallelly.
