It is because these responsibilities are separated that a Cilk program can run without rewriting on any number of processors, including one. The Cilk language has been developed since 1994 at the MIT Laboratory for Computer Science. It is based on

MIT licensed Cilk technology to Cilk Arts, Inc. of Lexington, MA, a venture-funded start-up founded by Charles E. Leiserson and Matteo Frigo. Cilk Arts developed Cilk++, a quantum improvement over MIT Cilk, which includes full support for C++, parallel loops, and superior interoperability with serial code. In July 2009 Intel Corporation acquired Cilk Arts. Intel has since released its ICC compiler with Intel Cilk Plus , which provides an easy path to multicore-enabling C and C++ applications.

Singh on parallel programming models and performance modeling. My fascination with parallel computers started during college at MIT, where I worked with the Cilk and RAW projects. After graduation I worked for a few years at Akamai Technologies where I learned how to apply algorithms to real problems and develop solid applications running on thousands of machines. Before going to college I attended the Computer Science High School in Bucharest, Romania. During this period I participated at several CS olympiads winning 3 times the 1st prize at national level, and 2 gold medals at international level at IOI'93 Argentina and IOI'94 Sweden. Hobbies and extra-curriculars include climbing, mountaineering, shotokan and taekwondo, playing chess, and photography. Research Interests Currently I'm working on parallel programming models and performance modeling of hierarchical interconnects (see Coarse Grain Dataflow home page). Previous related work includes :

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.

Next: Acknowledgments Up: Adaptive and Reliable Previous: Related work Conclusion The widespread use of NOWs for parallel computation requires a software infrastructure that allows programmers to code in a high-level language that abstracts away the complexity of protocols, scheduling, and resource management. Cilk and Cilk-NOW are part of this developing software infrastructure. In this paper, we have shown how Cilk-NOW's end-to-end design leverages structure in the Cilk programming model to implement adaptive parallelism and fault tolerance simply and efficiently. All overheads are amortized against work-stealing operations, and the number of steals grows with the critical path and not with the work. This result is only possible because Cilk-NOW incorporates Cilk-specific policies at all levels of its design. The Cilk-NOW runtime system, as described in this paper and as currently implemented, supports the Cilk-2 language which is essentially functional in that it does not have support for a global address space or parallel I/O. More recent incarnations of Cilk for MPPs and SMPs have support for a global address space using "dag-consistent" distributed shared memory [ ], and we are currently working on extensions for parallel I/O. With these additions to Cilk, preserving Cilk-NOW's adaptive and fault tolerant execution model remains a challenging open problem. We are currently working on this problem. The dag-consistency model was conceived with adaptive parallelism and fault tolerance in mind, and we are investigating the idea of coupling our current return transactions mechanism with a causal message-logging mechanism [
