New technological developments like the Compute Express Link (CXL) allow the construction of massively-parallel computers with ultra-large memory systems composed of highly diverse byte-addressable memory layers. 
The latter might differ drastically wrt size, access latencies, bandwidth and/or non-functional properties like persistence. This has a tremendous impact on the sometimes decades old virtual memory subsystems of current main stream operating systems that need to be redesigned and adapted to these new possibilities.

In this seminar we will cover both the underlying technological level of CXL as well as the basics of traditional virtual memory systems opposed to upcoming modern tiered memory systems with terabytes of main memory.Some basic knowledge of classical virtual memory systems (as covered e.g. in operating systems II) is required for participation.
Students will be assigned a number of scientific papers on related topics they have to report on in an oral presentation with slides and a written summary on the assigned topic.
Additionally, regular attendance is mandatory to receive the credits.
