Abstract

J-Cell aims at providing a single system image (SSI) in clusters of heterogeneous many-core processors. The project’s fully decentralized runtime environment is designed to hide the underlying hardware complexity, provide robustness in face of hardware failures, and allow applications to scale across a large number of processor cores.

J-Cell is built around the concept of globally accessible objects (GAOs), which can float freely in the system, and which encapsulate all the application state, including the thread’s execution contexts. A transaction-based consistency mechanism hides the synchronization latencies. The transaction system’s versioning approach also provides the redundancy that guards against failing processor nodes.

First results from simulation studies are encouraging. An actual implementation of the entire system is ongoing work.
