hi, friends i wrote a code in c#.net and it's ok. but i have a problem which is running slow i hope thare is some suggestions my code is folow static void calis(int rer, int dizin) { while (it < iterasyon && mmse <= 0.00001) { mmse = 0; mae = 0; for (int nf = 0; nf < orneksay; nf++) { mmse += hesaplas(ndata, nf); trains(nf); }//nf mmse = 0.5 * (mmse / (orneksay * nron)); if (it % 100 == 0) { yazs.WriteLine(mmse.ToString()); yazs.Flush(); } it++; }//it dosyas.Close(); yazss.WriteLine(rer.ToString() + " " + mmse.ToString() + " " + it.ToString()); yazss.Flush(); dosyass.Close(); } } i call calis function and i see cpu usage %25 mey it improve its performs ? can you help me? regads.

Please edit your original post, add PRE tags around the code so it gets all formatted and readable, and check some of it, I don't think while (it < iterasyon mmse <= 0.00001) could ever compile. :)

Getting an article published on CodeProject should be easier and faster.

Your code is very confusing. As Luc suggested, I wonder if it would compile.

I see the delay happening in this block. But we cannot help you till the time we don't know the initial value of mmse and what does hesaplas(ndata, nf) do? Also, what is the value of orneksay? There are so many loopholes here. Suggestion: Add two int counters. one in while loop and one in for loop just to notice how many times does this loop run. If this number is too high, you should probably consider ways to reduce them.

thanks for reply. i take notice of a point, when i look at cpu using, i observer my code is using cpu %25 and i have quad pc so i can't use %75 of my cpu performance is there this problem solution ? not: orneksay=dataset

No buddy... it is not. You are working on a single thread and it will try to squeeze as much time of processor as it can. I wouldn't suggest trying multithreading till the time you haven't sorted number of loops. I have a feeling that its just number of loops. Could you do that counter and tell us how many times while loop runs and how many times for loop runs?
