We present an O(1)-round fully-scalable deterministic massively parallel algorithm for computing the min-plus matrix multiplication of unit-Monge matrices. We use this to derive a O(log n)-round fully-scalable massively parallel algorithm for solving the exact longest increasing subsequence (LIS) problem. For a fully-scalable MPC regime, this result substantially improves the previously known algorithm of O(log(4) n)-round complexity, and matches the best algorithm for computing the (1 + epsilon)-approximation of LIS.
We describe a new randomized parallel algorithm for computing the planar convex hull of n points on a p processor-memory pair machine communicating through a network for which O(log p) routing is possible. We show tha...

We describe a new randomized parallel algorithm for computing the planar convex hull of n points on a p processor-memory pair machine communicating through a network for which O(log p) routing is possible. We show that the algorithm has optimal O(n log n/p) performance provided that p = o(n/log3n). We report extensive computational experience with the algorithm which supports its theoretical claims.
We describe a randomized CRCW PRAM algorithm that finds a minimum spanning forest of an n-vertex graph in O(log n) time and linear work. This shaves a factor of 2log* n off the best previous running time for a linear-...

We describe a randomized CRCW PRAM algorithm that finds a minimum spanning forest of an n-vertex graph in O(log n) time and linear work. This shaves a factor of 2log* n off the best previous running time for a linear-work algorithm. The novelty in our approach is to divide the computation into two phases, the first of which finds only a partial solution. This idea has been used previously in parallel connected components algorithms.

In this paper, we present a dynamic load-balancing algorithm for parallel digital logic simulation making use of reinforcement learning We first introduce two dynamic load-balancing algorithms oriented towards balancing the computational and communication load respectively and then utilize reinforcement learning to create an algorithm which is a combination of the first two algorithms In addition, the algorithm determines the value of two important parameters the number of processors which participate in the algorithm and the load which is exchanged during its execution. We investigate the algorithms on gate level simulations of several open source VLSI circuits
