Grid Middleware • Situation today: • A mess • Situation tomorrow: • Will it still be a mess?
Grid Middleware Today • Many different implementations (“stack”) • Limited interoperability • Tuned for specific application domains • Political decisions (Europe vs. US vs. Nordic vs …..) • Standards/Policies are developing slowly and with limited reach • A few promising examples appeared lately like OGSA-BES, JSDL, DRMAA? • Comparison to Networks: Where is the TCP/IP? • Production quality? • Reliability • Scalability • Maintainability • Deployability • Manageability
Grid Middleware • Layers - what to focus on • Which functionality is required - at what layers • Which standards are really needed • Viable security infrastructure • How to improve middleware quality? • How to sustain development efforts? • Open source? • What’s the role of industry?
