Resource-independent execution support on exa-scale systems
Service-oriented Operating Systems
Processor and network architectures are making rapid progress with more and more cores being integrated into single processors and more and more machines getting connected with increasing bandwidth. Processors become heterogeneous and reconfigurable, thus allowing for dynamic adaptation to specialised needs. In future, thousands of billions of devices may be connected to form a single computing unit.
No current programming model is able to cope with this development, as they are too tightly coupled with the underlying device structure. Furthermore, complex, non-aligned middlewares and operating systems render the programming model unnecessarily inefficient. In order to realise efficient programmability of terascale devices by experts and average developers equally, a complete new approach to handling these types of devices across all layers is required:
Service-oriented Operating Systems (S(o)OS) address the needs of future distributed systems by drawing from service-oriented architectures (SOA) and the strengths of Grids. S(o) operating systems are modular and minimal, optimised to fit into the cache of distributed compute units and enable process-centric management of resources and distributed execution, thus maximising the resource usage whilst minimising overhead.

| Transactional Memory Discussion on LinkedIn |
Are Transactional Memories the way forward in scalable computing systems? Software Transactional Memories are better in avoiding deadlocks and in dealing with contention management, and scale better than traditional locking techniques, but on the other hand, transactions are often accused of scaling badly. |
