Überblick
Fast prime counting function program and C/C++ library
Verlauf
primecount is a command-line program and C/C++ library for computing the prime-counting function π(x), using optimized parallel implementations of combinatorial algorithms.
Kim Walisch developed primecount as a high-performance implementation of combinatorial prime-counting algorithms. The project supplied open-source implementations of Deleglise–Rivat and Xavier Gourdon’s algorithm, progressively adding shared-memory parallelism, distributed MPI execution, improved load balancing, and APIs for C and C++.
Release 3.0 merged MPI support into the main project in 2016. Release 5.0 introduced Xavier Gourdon’s algorithm in 2019, and 5.1 made it the default for sufficiently large inputs. Subsequent releases focused on performance, testing, portability, and packaging.
primecount became available through operating-system package managers including Homebrew, Arch, Debian/Ubuntu, Fedora, FreeBSD, openSUSE, Nix, APK, and WinGet. The official project reports its use in several prime-counting-function world-record computations.
Users run primecount to calculate the number of primes less than or equal to a supplied value or call libprimecount from C/C++. Advanced options select particular algorithms, threads, status output, and verification modes; suitable builds can use OpenMP and MPI for large computations.
primecount packages research-grade number-theory algorithms as both a practical command and a reusable native library. It is notable to performance enthusiasts for its OpenMP parallelism, optional MPI distribution, 128-bit-scale computations, load balancing across many cores, and close coupling with libprimesieve.
