SC2Mapster

Hey, thanks for the input!

Of course loop unrolling will screw readability and there are more obvious methods to improve performance, but I simply wanted a second opinion on that. As the map will be SP only (at least for the prototype), maybe there won't be any performance issues after all.

Yeah, that's what I thought, too. And, God forbid, I would probably hit the script limit pretty soon :)

Hey,

I just started a rather ambitious economy simulation project where I have to loop a lot through various arrays/structs, some of them with constant values. When looking for a way to optimize perfomance right from the start, I stumbled upon loop unrolling:

e.g.

for ( i=0 ; i<8 ; i=i+1 )
    dest[i] = src[i];

becomes

dest[0] = src[0];
dest[1] = src[1];
dest[2] = src[2];
dest[3] = src[3];
dest[4] = src[4];
dest[5] = src[5];
dest[6] = src[6];
dest[7] = src[7];

The value assignments for my arrays are generated within an VBA automated excel sheet, so I can change values and generate new unrolled loops very fast.

But I am curious, has anyone of you tested loop unrolling with Galaxy to find out if there is any relevant performance advantage? Or will the Galaxy compiler do this for me by itself?
