Focus: "System Software for disruptive Memory Technologies"

Main memory, one of the central components of computer systems, has increasingly gained relevance. However, basic properties of the interface between memory and software remained the same despite increased capacities and access speeds: main memory is volatile, passive and mostly homogeneous. These assumptions also shape the expectations of software developers.

Recent developments invalidate these assumptions and thus are disruptive for industry as well as computer science research. Non-volatile memory modules in server systems as well as microcontrollers and high-bandwidth memory modules in HPC systems are already in use. In addition, current research in in- and near-memory computing is expected to enable high grades of parallelism by exploiting data locality properties.

In turn, this enables important improvements of computer system properties, e.g., the reduction of energy consumption, performance and reliability improvements, simplifications and reduced costs. However, it is still an open research question how current as well as future software and systems can make use of these innovations.

The "3rd Winter School on Operating Systems" of the Operating Systems Special Interest Group of the German Computer Science Society (GI) primarily offers
PhD students as well as early-stage researchers the opportunity to stay up to date with current developments of system software for systems using these disruptive memory technologies. Like in the previous 2016 and 2019 editions, a compact program comprising lectures, industry talks, and hands-on laboratories/hackathons will be offered to convey theoretical as well as practical information and knowledge. In addition, WSOS as a recurring event of the OS SIG is intended to be a platform for networking and exchange with renowned invited speakers from academia and industry. The working language of WSOS is English.


Planned  program:

  • 6 lectures (by international experts)
  • 4 industry talks (on current topics and future perspectives)
  • 2 work-in-progress sessions (to introduce the participants and their research topics)
  • 1–2 hackathons (to gain detailed knowledge about specific topics)
  • Discussion rounds by and with national and international researchers and experts
  • Diverse social events (for discussion and networking)
  • Extent: ca. 16 SWS (a confirmation of participation will be provided which can be handed in at the students' university. Please confirm the acceptance of winter school participation credits with your organization.)


Target audience:

  • PhD students
  • Early stage researchers
  • Possibly outstanding master student in the area of operating systems
  • Representatives from the industry


Number of participants: ca. 50 (selected in an application process)
