Non-Uniform Memory Access (NUMA) Seminar

Winter 2014/15

Prof. Dr. Andreas Polze

Felix Eberhardt, M.Sc.
Frank Feinbube, M.Sc.

Organization

Extent: 2 semester hours (3 graded credit points)

Dates: Wednesday, 11.00 - 12.30, HS3

The seminar focusses on literature review. Participants are required to read fundamental scientific publications on non-uniform memory access (NUMA) systems, and present them to their fellow students.
  • Each participant is expected to give a 30-45 minute presentation on a topic.
  • Presentation slides should be discussed with a supervisor one week prior to the presentation date.
  • At the end of the seminar, we plan to assemble a technical report about your seminar topics.

Topics

1. NUMA system architecture

1.1 Multiprocessor architectures (historic, current): AMD, Intel, IBM, Sparc
1.2 Interconnection technologies
1.3 Cache coherency

2. Operating systems

2.1 Scientific approaches: Thread and data placement
2.2 Topology discovery
2.3 Kernel APIs for thread and data placement

3. Programming models

3.6 PGAS (Unified Parallel C, Coarray Fortran, Fortress, Chapel, X10, and Global Arrays)
3.7 C++11 Memory consitency protocol

4. Profiling

4.1 Performance counter
4.2 Instruction based sampling
4.3 Scientific approaches: Profilers/analyzing runtime behaviour
4.4 Profiling tools: Intel, AMD, IBM, Sun/Sparc
