## twinprimes_ssoz.d
/* This D source file is a multiple threaded implementation to perform an
 * extremely fast Segmented Sieve of Zakiya (SSoZ) to find Twin Primes <= N.
 *
 * Inputs are single values N, or ranges N1 and N2, of 64-bits, 0 -- 2^64 - 1.
 * Output is the number of twin primes <= N, or in range N1 to N2; the last
 * twin prime value for the range; and the total time of execution.
 *
 * Code originally developed on a System76 laptop with an Intel I7 6700HQ cpu,
 * 2.6-3.5 GHz clock, with 8 threads, and 16GB of memory. Parameter tuning
 * would be needed to optimize for other hadware systems (ARM, PowerPC, etc).
