Scalable collective message-passing algorithms
… suffer the worst congestion when the largest messages are exchanged, damaging performance. Known algorithms for torus networks use only one network port, regardless of how many are available. Unlike known algorithms, our algorithms have a small amount of redundant communication. Unlike known …

Support for Send-and-Receive Based Message-Passing for the Single-Chip Message-Passing Architecture
… as PVM and MPI have made send-and-receive based message-passing the most popular programming model for distributed memory architectures. This thesis explores modifying the Single-Chip Message-Passing (SCMP) architecture to more efficiently support send-and-receive based message-passing. The …

Approximate Message Passing for Matrix Regression
Approximate message passing (AMP) algorithms have become popular in various structured high-dimensional statistical problems. Previous AMP algorithms for generalized linear models (GLM) typically require the signal to be in the form of a vector, and the design matrix to have independent and …

Message passing in a factored OS
… system processes that communicate with message passing rather than shared memory. This microkernel-based design has the potential for better performance and more efficient use of architectural resources. This is because each isolated address space can be scheduled on a separate dedicated …

Message passing: How software engineers use talk.
In this thesis I present software engineering as a social process in which programmers work together to create technical solutions. I propose that the social structures which developers create and within which they work provide the foundations from which they are able to collaborate to build …

Message Passing Algorithms for Statistical Estimation and Communication
… based on belief propagation (BP) and Approximate Message Passing (AMP), are developed for these problems. We first consider matrix sketching, where the goal is to recover an *n*<sub>1</sub> x *n*<sub>2</sub> low-rank matrix with *k*-sparse singular vectors from a small number of linear …

Message passing interface implementation for Concordia parallel programming environment
… we present the design and implementation of a Message Passing interface (MPI) [1] for the Concordia Parallel Programming Environment (CPPE), an environment for parallel computing simulation. The purpose of this project is to provide Message Passing Interface (MPI) support for CPPE, so that user …

Space reclamation for uncoordinated checkpointing in message-passing systems
… recovery from transient process failures. In a message-passing system, the rollback of a message sender may cause the rollback of the corresponding receiver, and the system needs to roll back to a consistent set of checkpoints called the recovery line. If the processes are allowed to take …

Feedback message passing for inference in Gaussian graphical models
… in a cycle-free graph. We propose a feedback message passing algorithm in which non-feedback nodes send out one set of messages while the feedback nodes use a different message update scheme. Exact inference results can be obtained in O(k²n), where k is the number of feedback nodes and n is …
