Faster remainders when the divisor is a constant: beating compilers and libdivide

Daniel Lemire

Not all instructions on modern processors cost the same. Additions and subtractions are cheaper than multiplications which are themselves cheaper than divisions. For this reason, compilers frequently replace division instructions by multiplications. Roughly speaking, it works in this manner. Suppose that you want to divide a variable n by a constant d. You have that n/d = n * (2 N / d ) / (2 N ).

Don’t read your data from a straw

Daniel Lemire

It is common for binary data to be serialized to bytes. Data structures like indexes can be saved to disk or transmitted over the network in such a form. Many serialized data structures can be viewed as sets of ‘integer’ values. That is the case, for example, of a Roaring bitmap. We must then read back this data. An integer could be serialized as four bytes in a stream of bytes.
