Why is there huge performance hit in 2048x2048 versus 2047x2047 array multiplication?
...n your cache. L is always power of 2.
The six comes from fact that 2^6 == 64 bytes is standard size of cache line.
Now what does this mean? Well it means that if I have address X and address Y and
(X >> 6) - (Y >> 6) is divisible by L (i.e. some large power of 2), they will be stored ...

Is floating-point math consistent in C#? Can it be?
... I found this not easier than using integers directly.
Implement FixedPoint64 in C#. I found this rather hard to do. For some operations intermediate integers of 128bit would be useful. But .net doesn't offer such a type.
Implement a custom 32 bit floatingpoint. The lack of a BitScanReverse intrinsi...
