It features a Weyl-sequence as part of the state. In general testing, **stc64** is the fastest among *pcg64*, -*xoshiro256`**`*, *sfc64*, and *lehmer64*. *wyrand* is faster on platforms with fast 128-bit -multiplication, and has 2^64 period length (https://github.com/lemire/SwiftWyhash/issues/10). -However, it is not suited for massive parallel usage due to its limited total minimal period length. +*xoshiro256`**`*, *sfc64*, and *lehmer64*. + +*wyrand* is faster on platforms with fast 128-bit multiplication, and has 2^64 period length +(https://github.com/lemire/SwiftWyhash/issues/10).
