I developed an application / benchmark that calculates PRIME numbers using a multithreaded parallel algorithm written in C++ and assembler. The software calculates prime numbers from 1 to 1.000.000.000 [one billion].

A slider will help you set the exact interval: from 1 to 10.000.000 [ten millions] and up to 1.000.000.000 [1 billion]. The default value of the slider is 100.000.000 [one hundred millions]. In that case, the application will calculate all the prime numbers between 1 and 100 millions.

Also, you can create a datafile that can be used to submit results to HWBOT.

My laptops i3-2330m did 1 to 100000000 in 1 minute 15 seconds, thats 2 cores 4 threads running at 2.2ghz. My 2500k did that same test in 19 seconds with 4 cores.

Honestly I like the benchmark. It does not show my overclock in the cpu frequency spot like others above does.

Okay, just ran the new version, same result. I find it odd that I can beat an sb-e running faster than me though?

Please get your x86 build sorted!

Plus, I would recommend a very simple UI thread updating showing that the thing is still "live". It only needs to update once every 5 seconds. That is no overhead and will not throw the results.

PS. I like the "video of the day" on your site. Funny! True!

Only the last version is available for download. I see some "." in the path in your screen, is the path correct, doesn't contain illegal characters?

I'l test some possibilities to add a UI refresh thread. Any sugestions about the benchmark?

I find it very interesting that the i7 950 is scoring higher than my i7 3820 even though the 3820 is faster and newer. According to this the 950 is faster than the 3820. :confused:

Me too.

I see some "." in the path in your screen, is the path correct, doesn't contain illegal characters?
A period is an acceptable character for a windows path. A bad path wouldn't give an "invalid win32 app." error.

In defense of the application, both 32 and 64-bit versions work for me. Maybe it doesn't support Win XP / Server 03?

Make sure you have .NET 4.0 installed as well.

Are you testing the x86.exe in a 64-bit environment? Or W32? I think the build is faulty and not x86 compatible. It might somehow be x86 code (ie compiler using only 32bit code) but in a x64.exe wrapper.

The benchmark is developed using Visual C++ 2012 wich doesn't support Windows XP and Windows Server 2003.

You don't need .Net Framework 4.0, the application is written using Visual C++ and MFC [native code, not managed].
