Studies suggest that it typically takes 20 years to go from the discovery of new materials to fabrication of new and next generation devices based on new materials. Many other scientific domains show similar delays. These scientific cycles must be shortened, and it will require a major transformation in how we collect digital data about physical artifacts from scientific instruments, and how we make the digital data available to computational tools for developing new materials, fabricating new devices, and speeding up the discoveries in science.These scientific cycles must be shortened, and it will require a major transformation in how we collect digital data about physical artifacts from scientific instruments, and how we make the digital data available to computational tools for developing new materials, fabricating new devices, and speeding up the discoveries in science.|
We will discuss novel cloud-based services, and algorithms that are an integral part of 4CeeD for collecting and correlating data from microscopes and fabrication instruments, modeling of scientific workflows in clouds as micro-services, self-adaptive micro-service-based infrastructure for heterogeneous scientific workflows, and role of edge computing. Specifically, we will show that our micro-service based approach helps to improve flexibility of workflow composition and execution, and enable fine-grained scheduling at task level, considering task sharing across multiple workflows. Furthermore, the self-adaptive micro-service management employs integration of feedback control, machine learning and optimization frameworks to offer resource adaptation without any advanced knowledge of workflow structures. We will also discuss a unique usage of edge computing to enable integration of aging instruments to be integrated into the micro-service operating infrastructure.
The evaluation of the 4CeeD system shows robust prediction of resource usage and adaptation under dynamic workloads, real-time service to users to offload, curate and analyze data, and access to diverse instruments.
