Deposit Collectors?

Informal lending and savings institutions exist around the world, and often include regular door-to-door deposit collection of cash. Some banks have adopted similar services in order to expand access to banking services in areas that lack physical branches. Using a randomized control trial, we investigate determinants of participation in a deposit collection service and evaluate the impact of o...

Colimits for Concurrent Collectors

This case study applies techniques of formal program development by specification refinement and composition to the problem of concurrent garbage collection. The specification formalism is mainly based on declarative programming paradigms, the imperative aspect is dealt with by using monads. We also sketch the use of temporal logic in connection with monadic specifications.

Cache-Conscious Copying Collectors

Garbage collectors must minimize the scarce resources of cache space and off-chip communications bandwidth to optimize performance on modern single-chip computer architectures. Strategies for achieving these goals in the context of copying garbage collection are discussed. A multi-processor mutator/collector system is analyzed. Finally, the Intel 80860XP architecture is studied.
