Eden is a parallel extension of the functional language Haskell. Eden inherits from Haskell its laziness, which allows it to avoid unnecessary computations. However, in order to enable the parallel execution of processes in Eden, this feature must be disabled when new processes are instantiated. Hence, any newly created process can be speculative, as it is not known whether the computations it ...

Eden is a parallel extension of Haskell allowing the programmer to explicitly specify which expressions must be evaluated as parallel processes. Eden is implemented by modifying the Glasgow Haskell Compiler (GHC). This decision has saved a lot of work but has also produced some drawbacks: Some optimizing transformations done by GHC are not convenient for Eden, either because they spoil its sema...

Crowd sensing applications have demonstrated their usefulness in many real-life scenarios (e.g., air quality monitoring, traffic and noise monitoring). Preserving the privacy of crowd app users is becoming increasingly important as collected geo-located data may reveal sensitive information about these home, work places, political, religious, sexual preferences). In this context, a large variet...

Classical results on the surjectivity and injectivity of parallel maps are shown to be extendible to the cases with non-Euclidean cell spaces of particular types. Also shown are obstructions to extendibility, which may shed light on the nature of classical results such as the Garden-of-Eden theorem. Key–Words: Cellular automata, Non Euclidean cell spaces, the Garden-of-Eden theorem

We prove a converse to Moore’s “Garden-of-Eden” theorem: a group G is amenable if and only if all cellular automata living on G that admit mutually erasable patterns also admit gardens of Eden. It had already been conjectured in [11; 1, Conjecture 6.2] that amenability could be characterized by cellular automata. We prove the first part of that conjecture.

The explicitly parallel programming language Eden adds a coordination level to the lazy functional language Haskell. This paper describes how a compiler and runtime system for Eden can incrementally be built on the basis of a compiler and runtime system for the computation language. The modiications needed in the compiler are restricted to speciic orthogonal extensions. We show that Eden's desi...
