Extractions: on Networks of Workstations Robert D. Blumofe, University of Texas, and Philip A. Lisiecki, MIT 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.

Implemented entirely in user-level software on top of UNIX, Cilk-NOW is a runtime system for a functional subset of the parallel Cilk language [ ], a multithreaded extension of C. Applications written in Cilk include graphics rendering, backtrack search, protein folding [ ], and the *Socrates chess program [ ] which won second prize at the 1995 ICCA World Computer Chess Championship running on the 1824-node Intel Paragon at Sandia National Labs. Like all runtime systems for Cilk, Cilk-NOW schedules threads using a provably efficient algorithm based on the technique of random "work stealing" [ ] in which processors with no threads steal threads from victims chosen at random. With this algorithm, Cilk delivers performance that is guaranteed to be both efficient and predictable [ ]. In addition to thread scheduling, Cilk-NOW also performs

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. The most recent release of Cilk is Cilk-5.3.2

Extractions: First Prize in the 1998 ICFP Functional Programming Contest went to Cilk Pousse, a program written in the Cilk multithreaded programming language being developed by the Supercomputing Technologies research group (SuperTech) of the MIT Laboratory for Computer Science (LCS). Although Cilk is not a functional language, it provides high-level linguistic abstractions for parallelism, and the contest was explicitly open to programs written in any language. (Half the entries were programmed in C.) The challenge task was to write a program to play the game of ``Pousse'', a variant of tic-tac-toe played on an N -by- N board. The programs competed on a 4-processor Pentium Pro machine running a Linux operating system. Teams had 72 hours to complete the programming. Almost 50 programs were entered into the contest. In the course of the competition, the Cilk Pousse program was undefeated in all games, even though in Pousse, the first player has a significant advantage. The First Prize citation recommends Cilk as ``the superior programming tool of choice for discriminating hackers.''

Extractions: Top All Packages in Directory cilk Cilk is designed for general purpose parallel programming, but it is especially effective for exploiting dynamic asynchronous, parallelism. The current release runs on symmetric multiprocessor machines that support Posix threads, GNU make, and gcc. You can also run Cilk on uniprocessor machines, which is useful for development and debugging, although you won't get any parallel speedup. According to cilk, a programmer should structure a program to expose parallelism and exploit locality, leaving the runtime system to schedule the computation to run efficiently. Thus, the runtime system handles details like load balancing, paging, and communication protocols. Unlike other multithreaded languages, however, cilk is algorithmic in that the runtime system guarantees efficient and predictable performance.

Although the two systems present significantly different parallel processing models, we attempted to code the benchmark problems in similar ways. The problems selected were matrix multiplication, travelling salesman problem, quick sort, Gaussian elimination, fast Fourier transform and finite differencing. We compared run times, speed-ups and coding efficiency as measured by lines of code in our implementations of the problems. ...

Extractions: Next: Adaptive parallelism Up: Adaptive and Reliable Previous: The Cilk language and The Cilk-NOW runtime system consists of several component programs that (in addition to macroscheduling duties discussed later) manage the execution of each individual Cilk program. In this section, we shall cover the architecture of a Cilk program as it is executed by the Cilk-NOW runtime system, explaining the operation of each component and their interactions. In Cilk-NOW terminology, we refer to an executing Cilk program as a Cilk job . Since Cilk programs are parallel programs, a Cilk job consists of several processes running on several machines. One process, called the clearinghouse , in each Cilk job runs a system-supplied program called CilkChouse that is responsible for keeping track of all the other processes that comprise a given job. These other processes are called workers . A worker is a process running the actual executable of a Cilk program. Since Cilk jobs are adaptively parallel, the set of workers is dynamic. At any given time during the execution of a job, a new worker may join the job or an existing worker may leave. Thus, each Cilk job consists of one or more workers and a clearinghouse to keep track of them. The Cilk-NOW runtime system contains additional components that perform macroscheduling as discussed in Section 6 , but for the purpose of our present discussion, we need only introduce the "node managers."
