manticore is a programming language created in 2009. The Manticore project is an effort to design and implement a new functional language for parallel programming. Unlike many earlier parallel languages, Manticore is a heterogeneous language that supports parallelism at multiple levels. Specifically, the Manticore language combines Concurrent ML-style explicit concurrency with fine-grain, implicitly threaded, parallel constructs. These lectures will introduce the Manticore language and explore a variety of programs written to take advantage of heterogeneous parallelism. At the explicit-concurrency level, Manticore supports the creation distinct threads of control and the coordination of threads through first-class synchronous-message passing. Message-passing synchronization, in contrast to shared-memory synchronization, fits naturally with the functional-programming paradigm. At the implicit-parallelism level, Manticore supports a diverse collection of parallel constructs for different granularities of work. Many of these constructs are inspired by common functional-programming idioms. In addition to describing the basic mechanisms, we will present a number of useful programming techniques that are enabled by these mechanisms. Finally, we will briefly discuss some of the implementation techniques used to execute Manticore programs on commodity multicore computers.
