Failure resilience in federated ecosystems for instrument science is a critical challenge. Failures disrupt experiments and make them potentially useless, wasting valuable instrument, network and computing allocations and creating setbacks for scientists. Oak Ridge National Laboratory’s (ORNL’s) Interconnected Science Ecosystem (INTERSECT) Initiative offers a federated ecosystem for instrument science, enabling autonomous experiments, self-driving laboratories, smart manufacturing, and artificial intelligence (AI) driven design, discovery, and evaluation. While it currently does not offer failure resilience, existing INTERSECT experiments require it, such as to reliably steer an autonomous additive manufacturing (AAM) process using real-time data streamed to a simulation in the feedback loop.

This project creates a resilient INTERSECT ecosystem architecture using resilience design patterns, a resilient system of systems (SoS) architecture, and a resilient microservices architecture. Its proof-of concept prototype implements a resilient federated ecosystem using the INTERSECT software development kit (SDK) and demonstrates resilience capabilities for the INTERSECT AAM cross-facility experiment between the Manufacturing Demonstration Facility (MDF) and the Oak Ridge Leadership Computing Facility (OLCF) Advanced Computing Ecosystem (ACE) testbed. The outcome of this project facilitates the proper development and deployment of resilience for federated ecosystems. It creates, implements and demonstrates a consistent design methodology that allows scientists to pick and choose the right solution for the resilience problem at hand and deploy it with ease. It enables a resilient federated ecosystem that facilitates the US Department of Energy’s (DOE’s) Integrated Research Infrastructure (IRI) vision.
