Mono SIMD Tests

Fri, 02/06/2009 - 07:58 — johann.nadalutti

I have done some performances tests:
The goal is to generate a 4096x4096 gradient texture (same as fxgen 'Gradient' operator) in order to compare C++ and C#.
I use mono 2.2 C# compiler under windows with and without new SIMD extension! (Thanks to Miguel de Icaza)

Results tests in ms:
In MS C 235 (VS Release Mode SIMD)
In MS C 360 (VS Release Mode 4D Float)
In Mono C# 453 (With Mono SIMD)
In Mono C# 562 (With Mono 4D Float)
In MS C# 609 (VS With 4D Float)
In MS C 672 (VS Debug Mode)

Then main idea is to see if a 100% C# version of fxgen could be possible.
That could allow users to create their own operators directly into the editor in C# script.
This operators could be write in C# then compiled and optimized by mono JIT for target CPU.

SIMD extension for Mono is really a good idea...

That sounds very nice.

That sounds very nice. Looking forward to it! The few texture generators I used all based on parameters and few fixed operators. Using own code would be very helpful, as you can design own operators the way you need them. Whats missing currently are especially customizable noise functions. Important things like scratches are very difficult to do. The other thing is mapping operators to specific areas of your textures with alphamaps.
