The aim of this Priority Programme is therefore to explore the potentials of ongoing developments in the field of main memory technologies and architectures. Despite the disruptive nature of these technologies, systems software and applications shall be enabled to fully exploit them. In order to master disruptive memory technologies and their impact on the overall memory hierarchy, research efforts are required on all levels of the classic system software stack, for example:

o Computer Architecture (Technical Computer Science): innovative architectures, for example, sensor nodes with fully-persistent state; improving/adapting existing architectures, for example, issues of volatile and non-volatile memory co-existence; instruction set extensions and memory management units
o Operating Systems: software abstractions for new types of memory; integration into the memory hierarchy; fine-grained isolation and sharing of persistent objects; synchronisation mechanisms and memory transactions; systems that never reboot; removal of "persistent" faults or bugs
o Algorithms / Data Structures: dealing with heterogeneity (high/low bandwidth, different read/write performance); lightweight transactions on data structures
o Databases: optimised usage of different memory types, for example, index structures in persistent memory or optimised query execution
o Languages / Compilers / Software Engineering: support for In/Near-Memory Computing; evolution of persistent state; extended type systems and other models for novel classes of memory; conversion of legacy software; potential bugs related to the new technology

Proposed projects must have a clear relation to the above-mentioned aim of the Priority Programme. The addressed research questions are expected to be evolutionary (improving existing systems in a focused manner), disruptive (making use of novel memory technology for new and potentially incompatible features), or visionary (rethinking systems completely). All three kinds of projects are welcome and cross-project collaboration during the runtime of the project will be encouraged for mutual benefit.
