New download link with id=666 xD Evil benchmark! :D

Going to check it out.

Ok, program tested. All 4 cores in 100% usage during the test so it is really good job done :) And i hope you will revert slider. Here is my score:



And for incorrect cpu speed detection i would suggest you to perform little bench while detecting speed to make readings proper.

Ultimate Multi Core PI

The graphical user interface has been rewritten in C# and WPF 4.0 [the application needs Net Framework 4.0].

The core of the benchmark was moved to a DLL written in Visual C + + [calculation algorithm and parallelization] so that benchmarks results are not altered at all.

New look:

Because we want to be sure that all users are benching with the same settings... Any requests beside decimal slider?
Having just a handful of presets might be preferable if people want some other options.

It's going to take a very very long time to complete with 360.000 decimals. It will complete at one time, just leave the benchmark running. It's exponential complexity. For 10k decimals its takes in 0 sec, 800ms, for 20k decimals 2 sec 900ms... and for 80k decimals 54 sec. CPU: i5 3330 @ 3Ghz, 4 cores.

It's multi-threaded. 8 threads at 3.5GHz > 4 threads at 4.6GHz in multithreaded apps(that can utilize 8 threads) because you can get much more throughput.

I clicked on the link to download it and it just says "You've been permanently banned from the forums"...

Guess I don't get to try it.

with HT ON 4.6ghz. but why should we turn off HT ? more and more games/software are being designed for multithreaded optimization..

Here is mine. The correct frequency is 3.6GHz though:



Possible bug: I use multiple monitors. When I clicked Submit to HWBOT to get the screen shot, it took a screenshot of my primary monitor, which didn't have the Multi Core Pi window on it.

Also, why it is so slow? I'd expect a multi-threaded Pi program to calculate Pi a heck of a lot faster than this. Or did you intentionally make it slow because it is meant to be a benchmark?

Works well except the CPU Frequency is wrong. I set power options to performance to force the CPU clock to 4.5Ghz, but it doesn't make a difference.
