The Cilk Project Download Introduction Online Manual ... Papers Cilk Cilk is a language for multithreaded parallel programming based on ANSI C. Cilk is designed for general-purpose parallel programming, but it is especially effective for exploiting dynamic, highly asynchronous parallelism, which can be difficult to write in data-parallel or message-passing style. Using Cilk, our group has developed three world-class chess programs, StarTech, *Socrates, and Cilkchess. Cilk provides an effective platform for programming dense and sparse numerical algorithms, such as matrix factorization and N-body simulations, and we are working on other types of applications. Unlike many other multithreaded programming systems, Cilk is algorithmic, in that the runtime system employs a scheduler that allows the performance of programs to be estimated accurately based on abstract complexity measures. Click here for a brief introduction to Cilk. The Cilk-5.3.2 Reference Manual contains a programming guide with a short tutorial on the Cilk language. Latest Version The most recent release of Cilk is Cilk-5.3.2

Cilk Programming Language Critique by Minglun Qian Summary Silk is a multithreaded parallel programming language based on ANSI C. With only a few added keywords like cilk, spawn, sync, inlet, abort, shared and lock Cilk is able to start, synchronize and terminate a parallel Cilk procedure easily. With the " work stealing " scheduling, cilk can balance the workload dynamically and achieve high efficiency as the creator claimed. Cilk is designed to provide a dynamic, asynchronous procedure oriented parallel programming environment and targets at computations with divide-and-conquer algorithm and tree search algorithm involved. Another goal of Cilk is to let a Cilk programmer concentrate on structuring the program and leave the responsibility of efficiently scheduling the computation to the runtime system. Abstraction Overall, Cilk is able to provide a consistent abstraction of Cilk-procedure Cilk-thread and operations on it although the definition on the thread is pretty away from a traditional definition. The consistent abstraction makes the Cilk programmer being able to program a multithreaded application with ease. Introduction of the Inlet concept sometimes makes programming easier.

Abstracts - 1997 ANNUAL TECHNICAL CONFERENCE Adaptive and Reliable Parallel Computing on Networks of Workstations Robert D. Blumofe, University of Texas, and Philip A. Lisiecki, MIT Abstract In this paper, we present the design of Cilk-NOW , a runtime system that adaptively and reliably executes functional Cilk programs in parallel on a network of UNIX workstations. Cilk (pronounced "silk") is a parallel multithreaded extension of the C language, and all Cilk runtime systems employ a provably efficient thread-scheduling algorithm. Cilk-NOW is such a runtime system, and in addition, Cilk-NOW automatically delivers adaptive and reliable execution for a functional subset of Cilk programs. By adaptive execution, we mean that each Cilk program dynamically utilizes a changing set of otherwise-idle workstations. By reliable execution, we mean that the Cilk-NOW system as a whole and each executing Cilk program are able to tolerate machine and network faults. Cilk-NOW provides these features while programs remain fault oblivious , meaning that Cilk programmers need not code for fault tolerance. Throughout this paper, we focus on end-to-end design decisions, and we show how these decisions allow the design to exploit high-level algorithmic properties of the Cilk programming model in order to simplify and streamline the implementation.

1 Functional programming and parallel computations The idea to use functional programming features for parallel computations is old enough. The most important of these features is the fact that functions without side effects can be computed in arbitrary order, so a programmer is freed of a number of problems connected to computations synchronization. However, there is no program architecture that is generic enough, and the advantages of functional approach are compensated by programming style limitations which often are hardly compatible with traditional imperative programming languages. That is why a pure parallel graph reduction is primarily used for implementation of functional programming languages [ ]. Though parallel implementations of imperative programming languages using some functional programming features also exist. Maybe the best known implementation is Cilk programming language [ ]. Another example immediately preceding authors work is T-system package which is developed in Program Systems Institute of Russian Academy of Sciences [ ]. We should mention the following T-system features that are also peculiar to the technology described in this paper:

Most parallel programming languages are conventional or sequential programming languages with some parallel extensions. A compiler is a program that converts the source code written in a specific language into another format, eventually in assembly or machine code that a computer understands. For message-passing based distributed memory systems, "compilers" often map communication functions into prebuilt routines in communication libraries. Some systems listed here are basically communication libraries. However, they have their own integrated utilities and programming environments.

The winners First Prize First prize went to the MIT Cilk Pousse team, whose entry crushed all opponents in its path, not losing a single game in the finals. The Cilk Pousse team has the following members: Reid Barton Chris Joerg Dan Adkins Martin Rinard Harald Prokop Don Dailey Matteo Frigo Charles Leiserson The judges felt the Cilk team made such a strong showing for several reasons: Expertise: The Cilk project has a lot of experience in game tournaments, having competed strongly in chess tournaments before. Parallelism: Cilk is a language designed for parallelism, and was able to exploit the tournament machine's four processors quite efficiently. The Cilk entry was the only entry that employed a really sophisticated parallel search algorithm. What the Cilk Pousse team delivered was a brutal search engine, that pumped out immense numbers of moves per second, similar to the strategies that produce championship chess programs. Organisation: At eight people, the Cilk Pousse team was the largest single team to enter, being comprised of two professors, one research engineer, one sysadmin, and four students (some graduate, some undergraduate, and even one local high-school student). ...and of course, general excellence and superior hacking.
