Unify: A Scalable, Loosely-Coupled,
Distributed Shared Memory Multicomputer
The objective of the Unify project is to develop a scalable distributed
shared-memory (DSM) multicomputer linking hundreds or thousands of high-performance
machines in geographically distant locations. There are five main areas
of research being addressed by the Unify project:
- New Scalable DSM Abstractions:
- We are developing new DSM abstraction that relax consistency and
synchronization requirements to produce better concurrency and mask the
high latencies of a wide-area system.
- Reliable Multicast
- We are developing a scalable reliable multicasting protocol called
TMTP to reduce bandwidth requirements and ensure timely reliable delivery
- Performance Monitoring Tool:
- We are developing a graphical user interface that monitors distributed
applications as they execute and helps users fine-tune performance.
- Adaptive Object Support:
- We are developing a reactive object library that will allow applications
to automatically adapt themselves to the current network environment to
attain better performance.
- We are adding support for Checkpointing and recovery in a system
with relaxed consistency requirements.
