Overview

CoRG is a research group in the Information and Comptuter Sciences Department at the University of Hawai`i at Manoa. CoRG researchers develop novel simulation models, algorithms, and systems for parallel and distributed computing platforms and applications. We study platforms including single clusters, grids that aggregate multiple high-end clusters across different institutions, and even thousands of volatile PCs scattered over the Internet. Our research results in strategies that help engineering and science applications exploit these platforms to the best of their capabilities.

Current Projects

   SimGrid is a toolkit that provides core functionalities for the simulation of distributed applications in heterogeneous distributed environments. This project is an international collaboration. You can find here a (2MB) PDF version of the SimGrid Poster.
Desktop Grids Investigation of how platforms that consists of non-dedicated PCs can support new classes of applications. Research activities include the understanding and modeling of resource availability as well as the design of resource selection and allocation strategies for parallel applications. (Most recent paper.)
Mixed-Parallel Application Scheduling Novel techniques for scheduling scientific mixed-parallel applications on parallel/distributed computing platforms. Mixed-parallel applications combine task and data parallelism, that is, they are structured as directed acyclic graphs of data-parallel tasks. (Most recent papers: paper #1, paper #2).
Job Scheduling in Virtual Clusters Novel job scheduling problems pertaining to resource sharing in parallel computing platforms that allocate resources to users using virtual machine technology.
Synthetic Resource Specification Generation A program that generates synthetic grid resource descriptions, based on this paper, is available as a tarball: GiST_v0.1.tar.gz.
