sieve of Eratosthenes, systematic procedure for finding prime numbers that begins by arranging all of the natural numbers (1, 2, 3, …) in numerical order. After striking out the number 1, simply strike out every second number following the number 2, every third number following the number ...
primesieve is a command-line program and C/C++ library for quickly generating prime numbers. It is very cache efficient, it detects your CPU's L1 & L2 cache sizes and allocates its main data structures accordingly. It is also multi-threaded by default, it uses all available CPU cores when...

This paper presents a new distributed approach for generating all prime numbers in a given interval of integers. From Eratosthenes, who elaborated the first prime sieve (more than 2000 years ago), to the current generation of parallel co... GAL Paillard,FMG França,C Lavault 被引量: 20发表...
The Sieve of Eratosthenes (1803) is an ancient method for finding prime numbers. A sieve is noted as something a witch sails in by 1580s; hence sieve and shears, formerly used in divination. sieve (v.) late 15c. (implied in verbal noun sieving), transitive, "sift through or as if th...

He is credited with devising analgorithmfor findingprime numberscalled thesieve of Eratosthenes, in which one arranges the natural numbers in numerical order and strikes out one, every second number following two, every third number following three, and so on, which just leaves the prime numbers...
Here’s a simple implementation in C. Notice that I use one array to store all the integers, and after I perform the sieve I move the remaining prime numbers into their own array. The program below will store and print the first 100,000 primes (you can adapt it easily for a larger ...
