"Massively parallel probabilistic computing with p-bits"

 "Massively parallel probabilistic computing with p-bits"

The slowing down of Moore's Law has led to a crisis as the computing workloads of Artificial Intelligence (AI) algorithms continue skyrocketing. There is an urgent need for scalable, energy-efficient hardware catering to the unique requirements of AI algorithms and applications. In this environment, probabilistic computing (p-computing) with p-bits [1] has emerged as a scalable, domain-specific and energy-efficient computing paradigm, particularly useful for probabilistic applications and algorithms. In this talk, I will describe two general applications of p-computing: optimization and learning as problems relevant to Machine Learning and AI. I will discuss two recent and representative [2-3] experiments illustrating how both problems can be efficiently addressed by a suitably modified magnetoresistive random access memory (MRAM) technology. I will then show standard silicon-based implementations of p-computing applied to practical optimization problems in large scale [4] to stress why nanodevice-based implementations of p-computing is a crucially needed ingredient.
