Ease (programming language)

Article summary

Ease is a general purpose parallel programming language. It is designed by Steven Ericsson-Zenith, a researcher at Yale University, the Institute for Advanced Science & Engineering in Silicon Valley, California, the Ecole Nationale Supérieure des Mines de Paris, and the Pierre and Marie Curie University, the science department of the Sorbonne. The book Process Interaction Models is the Ease language specification. Ease combines the process constructs of communicating sequential processes (CSP) with logically shared data structures called contexts. Contexts are parallel data types that are constructed by processes and provide a way for processes to interact. The language includes two process constructors. A cooperation includes an explicit barrier synchronization and is written: :: \parallel P() \parallel Q() ; If one process finishes before the other, then it will wait until the other processes are finished. A subordination creates a process that shares the contexts that are in scope when created and finishes when complete (it does not wait for other processes) and is written: :: \big /\!\!/ P() ; Subordinate processes stop if they attempt to interact with a context that has completed because the parent process has stopped. This enables speculative processes to be created that will finish if their result is not needed.…
