  • C-code by Frank Pilhofer - The author says "My not only fast but also saves memory, and its macros are almost completely ununderstandable." pop

  • Robert Bennion's Hopping Sieve - "The hopping sieve" was developed by Robert Bennion at the University of Utah in the early 1970s. This sieve MAY have advantages over other methods if you have a small or slow cache memory. This page contains links and C source code. pop

  • A compact prime sieve - 52 lines of portable ANSI C. Outputs roughly first and last sqrt(N) primes when searching primes up to N (rounded up to next multiple of 30), and finally reports #primes found. Compile with cc -O sieve.c -o sieve usage: ./sieve As an indication of speed, my AMD Athlon(tm) XP 2700+ PC computes all primes up to 10^9 in 12 seconds.

  • Cache-friendly fast segmented sieve of Eratosthenes - Fast generation of primes in a given interval. Works with 64-bit integers. Should be compiled with the gcc compiler. Works with 64-bit integers. Works quite fast near 1e16 or higher (but uses a lot of memory...).
