Message Passing and Threads
In this chapter we examine two fundamental, although low-level, approaches to expressing parallelism in programs. Over the years, numerous different approaches to designing and implementing parallel programs have been developed (e.g., see the excellent survey article by Skillicorn and Talia [870]). However, over time, two dominant alternatives have emerged: message passing and multithreading. T...
متن کاملMessage Passing and Combinatorial Optimization
Graphical models use the intuitive and well-studied methods of graph theory to implicitly represent dependencies between variables in large systems. They can model the global behaviour of a complex system by specifying only local factors.This thesis studies inference in discrete graphical models from an “algebraic perspective” and the ways inference can be used to express and approximate NP-har...
متن کاملApproximate Message Passing
In this note, I summarize Sections 5.1 and 5.2 of Arian Maleki’s PhD thesis. 1 Notation We denote scalars by small letters e.g. a, b, c, . . ., vectors by boldface small letters e.g. λ,α,x, . . ., matrices by boldface capital letter e.g. A,B,C, . . ., (subsets of) natural numbers by capital letters e.g. N,M, . . .. We denote i’th element of a vector a by ai and (i, j)’th entry of a matrix A by ...
متن کاملBiclustering Using Message Passing
Biclustering is the analog of clustering on a bipartite graph. Existent methods infer biclusters through local search strategies that find one cluster at a time; a common technique is to update the row memberships based on the current column memberships, and vice versa. We propose a biclustering algorithm that maximizes a global objective function using message passing. Our objective function c...
متن کاملProving Copyless Message Passing
Handling concurrency using a shared memory and locks is tedious and error-prone. One solution is to use message passing instead. We study here a particular, contract-based flavor that makes the ownership transfer of messages explicit. In this case, ownership of the heap region representing the content of a message is lost upon sending, which can lead to efficient implementations. In this paper,...
