Full expression→Symbol s→Article meaning
Where the article explains it
If each element occupies s bytes, the ratio of work done to bytes moved is
The passage around this formula
Multiplying an m k matrix by a k n matrix performs 2mnk floating-point operations while touching mk + kn + mn elements. If each element occupies s bytes, the ratio of work done to bytes moved is
