Cyberinfrastructure – the NEOS Project

Turn a jumble of software into a resource

Target: Large-scale optimization Components: modeling languages as well as solvers

Widely disseminate the resource via the Web Provide related educational tools

NEOS Guide LP & NLP Frequently Asked Questions

Scale it all up

Centralized scheduler, distributed solvers 2000-3000 submissions/week, peaks over 5000 Callable version (the Kestrel client)

Cyberinfrastructure – current NEOS research

Standards for problem representation Problem analysis and solver choice Documented callable interface (API) for the Server “Web service” interfaces Benchmarking and verification

Cyberinfrastructure – visions for DMII

Software as well as hardware

Finding “idle cycles” to run solvers Supporting the whole modeling life-cycle

(building – solving – analyzing – revising)

Resources for exponentially hard problems

Link modeling tools to high-performance computers Devise economic foundations for solver services

Education & dissemination

Online guides, case studies, listings Integration into new courses and fields

(in science, engineering, business)
