Calls to RANDOM_NUMBER from different threads can sometimes return the same value.
Intel® Digital Random Number Generator Software Implementation Guide
In introduction to the Intel® Digital Random Number Generator (DRNG). Includes prerequisite downloads and related software as well as an overview of DRNG use.
DotMix is a new user-contributed code that provides programmers with a repeatable but efficient way to deterministically generate pseudorandom numbers in parallel in Intel® Cilk™ Plus. In this post, I explain what "contributed code" is, where it comes from, and give a brief preview of DotMix.
Pedigrees are a new feature implemented in Intel Cilk Plus and currently available in Intel® Composer XE 2013. In this post, I explain what pedigrees are, how they work, and how you can use them in Cilk Plus. Pedigrees are a key component used in the implementation of DotMix, a contributed code for a deterministic parallel random-number generator (DPRNG) discussed in my previous post.
