A large number of MPI implementations are currently available, each of which emphasize
different aspects of high-performance computing or are intended to solve a specific research …

We describe our work on improving the performance of collective communication operations
in MPICH for clusters connected by switched networks. For each collective operation, we …

A conversational implicature is an inference that consists of attributing to a speaker an
implicit meaning that goes beyond the explicit linguistic meaning of an utterance. This paper …

We describe the design and implementation of DeepDive, a system for transparently
identifying and managing performance interference between virtual machines (VMs) co …

Abstract Model parameter synchronization across GPUs introduces high overheads for data-
parallel training at scale. Existing parameter synchronization protocols cannot effectively …

The GridFTP extensions to the File Transfer Protocol define a general-purpose mechanism
for secure, reliable, high-performance data movement. We report here on the Globus striped …

The Dutch Advanced School for Computing and Imaging has built five generations of a 200-
node distributed system over nearly two decades while remaining aligned with the shifting …

We discuss the design and high‐performance implementation of collective communications
operations on distributed‐memory computer architectures. Using a combination of known …

Application development for distributed-computing “Grids” can benefit from tools that
variously hide or enable application-level management of critical aspects of the …

Previous studies of application usage show that the performance of collective
communications are critical for high-performance computing. Despite active research in the …
