Software is sucks? Probably it really is!

Remember new features, that make your code unreadable? A couple of days ago, CLR team released first preview of Parallel Computing for .NET. Isn't it really cool, that now you can use full power of your computer? I decided to test the extension and wrote simple routine, that throttles your CPU.

static int i=0;
static void MessMe()
        {
            for (;;)
            {
                i ++;
                if (Console.KeyAvailable)
                {
                    Console.ReadKey(true);
                    break;
                }
            }
        }

Cool, now let's run it (with measurement) on my Dual Core 2 processor.

MessMe();

Nice, 54K simple math operations per second with half of each of my cores

It's already works (maybe because of my super OS?), but I still did not used it. Let's try to use the Parallel Computing extension.

Parallel.Do(MessMe);

What's going on with CPU?

Looks the same? Probably. Now the question is why the application performance degraded? Maybe it should know how much cycles I need?

And now with the Extension

Well, not really works. Let's try another method

Parallel.For(1, int.MaxValue, delegate(int k)
            {
                i = k;
                if (Console.KeyAvailable)
                {
                    Console.ReadKey(true);
                }
            });

 

Hmmm, it looks much better now, but still I do not understand that's going on here.

Yes, I know, this is stupid way to test framework and it's very early stage to judge, however, please someone can explain me what exactly wrong I'm doing?
