WebPritchard [17] showed how to apply a xed wheel to get a compact sieve that runs in linear time. Atkin and Bernstein [1] gave the rst compact sieve that runs in sublinear time. For … The sieve of Eratosthenes is a popular way to benchmark computer performance. The time complexity of calculating all primes below n in the random access machine model is O(n log log n) operations, a direct consequence of the fact that the prime harmonic series asymptotically approaches log log n. It has an exponential time complexity with regard to input size, though, which makes it a pseudo-polynomial algorithm. The basic algorithm requires O(n) of memory.
