Seminar: ‘Formalizing Garbage: Mathematical Models of Memory Management’ by Jeremy Singer

Event details

  • When: 6th October 2015 14:00 - 15:00
  • Where: Cole 1.33a
  • Series: School Seminar Series
  • Format: Seminar, Talk


Garbage collection is no longer an esoteric research interest. Mainstream programming languages like Java and C# rely on high-performance memory managed run time systems. In this talk, I will motivate the need for rigorous models of memory management to enable more powerful analysis and optimization techniques. I will draw on a diverse range of topics including thermodynamics, economics, machine learning and control theory.


Jeremy Singer is a lecturer at the School of Computing Science, University of Glasgow, Scotland. He has research interests in programming languages,compilation, run time code optimization and memory management. Singer received his PhD from Cambridge in 2006. Website:


School Seminar: Complex Networks and Complex Processes

Complex networks provide a way of modelling systems with lots of
dependent elements, such as traffic networks or social networks. By
running processes over these networks we can explore how the topology of
the network affects the way the process evolves, and potentially
identify factors that accelerate or impede it. This opens-up
possibilities both for study (science) and control (engineering).

This talk will briefly introduce the mechanics of complex networks and
the processes that run on them, review some recent results we have
obtained, and look to future research programme where we will combine
simulation with sensing to give us new ways of looking at the world.

Feldspar is a domain specific language with the goal of raising the
level of abstraction for performance sensitive, low-level code.
Feldspar is a functional language embedded in Haskell, which offers a
high-level style of programming. The key to generating generating
efficient code from such descriptions is to use a high-level
optimisation technique called vector fusion. Feldspar achieves
vector fusion for free by employing a particular way of embedding the
language in Haskell by combining deep and shallow embeddings.
