making parllel for loop with uses of all processor

KUNWAR999

here is my code, word is a string array. i want to convert this code into parllel ,so that i can reduce time and use all processor of my i5 processor system.. for (int i = 0; i < k1; i++) { for (int j = 0; j < k1; j++) { num[j][i] = Convert.ToInt32(words[count]); count++; } } can anyone help me out in this????

Easiest solution is to convert it to a parallel loop[^], available in .NET 4;

using System;
using System.Threading.Tasks;

class Demo
{
int N = 1000;

void TestMethod()
{
    Parallel.For(0, N, (i, loopState) =>
    {
        Console.WriteLine(i);
        if (i == 100)
        {
            loopState.Break();
        }
    });
}

}

If you need more control, you'd typically use a thread[^].

I tried this code.. but i m getting high execution time than its sequential code.. and parllel execution should take less execution time than sequential code.. :(

..if the problem can be solved using parallel threads, and only when implemented correctly. The example was the easiest method, but it's only a shorthand for a specific type of problem. You can spawn threads[^] to run code concurrently. It's usually the OS that decides on which core the thread runs, but I believe you can set it's affinity.

i hv tried it one more way as using #pragma omp parllel .. but vs2010 saying that its unrecognized concept.. actually i am avoiding using threads because i want to use parllel processing in processor directly.. :(

..and how would you do that?
