Analysis of the Go memory model

The task is to formalize resp. analyze aspects of Go's memory model, in
particular in connection with Go's communication and synchronizing

The Go language is a relatively recent arrival to the programming language
scene, and backed by Google for use in internal projects, upcoming Android
support, and use by third parties like Docker.

Go is expressive, concise, clean, and efficient. Its concurrency mechanisms
make it easy to write programs that get the most out of multicore and
networked machines, while its novel type system enables flexible and
modular program construction.

One important and tricky aspect of Go in connection with concurrency is Go's
memory model. As in basically all modern programming languages, Go
supports a weak memory model. Such memory models, while crucial for
efficient implementations and optimizing compilers reflecting advanced
modern hardware, are notoriously hard to formalize, to analyze, and to
program with.

The task of the master thesis is to provide means to analyze
executions in Go's weak memory model. That task involves

  •  getting a firm and precise grip on the semantics of the memory model.
  • find ways of analyzing, for instance statically, Go programs to
      detect situations where the program is not properly synchronized.
  • implement a prototype analyzer based on the developed theory
  • contribute to publications/conference submissions.


It may be possible to visit TU Darmstadt (Germany) during the thesis,
within the GoRETech-project.
