Disposal of dead actors in actor-model languages is as important as disposal of
unreachable objects in object-oriented languages. In current practice, programmers are …

Scientific and business communities are adopting large-scale distributed systems as a
means to solve a wide range of resource-intensive tasks. These communities also have …

The Oxford English Dictionary defines provenance as (i) the fact of coming from some

The use of remotely sensed data to estimate terrestrial properties usually involves the
acquisition of ground data. Remotely sensed data are being applied to ever larger areas …

We have developed a new programming language, called Pony, that allows the user to
easily write fast, safe, parallel programs. The focus of this work is using a powerful and novel …

We propose Pony-ORCA, a fully concurrent protocol for garbage collection in the actor
paradigm. It allows actors to perform garbage collection concurrently with any number of …

The use of real-time distribution middleware programmed with high-level languages like
Java is becoming of increasing interest in next generation applications. Technology like …

ORCA is a garbage collection protocol for actor-based programs. Multiple actors may mutate
the heap while the collector is running without any dedicated synchronisation. ORCA is …

An actor garbage collector (actor GC) is a tool for automatically identifying actors that are
safe to delete, and reclaiming their resources. Actor GC could be particularly useful in …

A reliable communication layer is an essential component of a mobile agent system. We
present a new fault-tolerant directory service for mobile agents, which can be used to route …
