longDescription = ''
|
|
primecount is a command-line program and C/C++ library that counts the
|
|
primes below an integer x ≤ 10^31 using highly optimized implementations
|
|
of the combinatorial prime counting algorithms.
|
|
|
|
primecount includes implementations of all important combinatorial prime
|
|
counting algorithms known up to this date all of which have been
|
|
parallelized using OpenMP. primecount contains the first ever open source
|
|
implementations of the Deleglise-Rivat algorithm and Xavier Gourdon's
|
|
algorithm (that works). primecount also features a novel load balancer
|
|
that is shared amongst all implementations and that scales up to hundreds
|
|
of CPU cores. primecount has already been used to compute several prime
|
|
counting function world records.
