I look an example in sdk Reduction:

size = 5<<20;

s>>=1

I look an example in sdk Reduction:

size = 5<<20;

s>>=1

So, what’s the question?

“>>’” and “<<” are shifts to the right and to the left respectively.

s>>=1 means s = s >> 1, i.e. s = s / 2

Aaaaa

size=5<<20= 5 * 2^20

right?

and one more:

if( tid % s ==0)
