Extractions: I used to work for Cilk Arts, a startup formed to commercialize the Cilk programming language from MIT. Cilk Arts was acquired by Intel in July, 2009. While financial terms were not disclosed, this was not one of those everybody-gets-rich deals. I'm not complaining about that worthless stock options are a customary risk of startups but don't think I am sitting on a mountain of money feeling sorry for myself. I left Intel in May, 2010. Seven ex-Cilk Arts employees were acquired in 2009. I was the fourth to resign. I was very nearly the first. This is part of the reason why I quit. Two missing sequence numbers are internal Intel matters that can remain that way. 1. The acquisition of Cilk Arts was super-secret, don't-even-tell-your-family secret, for no reason. If the only options were super-secret or public then Intel should have issued a press release once the preliminary deal was signed a month before close. I learned later that people inside Intel with need to know were not informed either. 2. Intel wasted my summer. I spent July and August in the office doing nothing. There was no meaningful work to do but I had to be around all the time in case something came up. I was not able to take a summer vacation like I planned and I started off with no accumulated vacation at Intel.

Extractions: * The Cilk++ programming platform reduces the challenge of multicore software programming. Cilk++ enables rapid development, testing and deployment of high-performance multicore applications. The solution consists of a simple set of extensions for the C++ programming language, a powerful runtime system and tools that ease the development of multicore software. * An irreversible shift towards multicore processors is underway, but multicore processors are parallel computers - and parallel computers are notoriously difficult to program. Writing, or rewriting, parallel (multithreaded) applications can be difficult, expensive, time-consuming and error-prone, and requires a new programming skill set.

Rinard This paper presents a novel interprocedural, flow-sensitive, and context-sensitive pointer analysis algorithm for multithreaded programs that may concurrently update shared pointers. The algorithm is designed to handle programs with structured parallel constructs, including fork-join constructs, parallel loops, and conditionally spawned threads. For each pointer and each program point, the algorithm computes a conservative approximation of the memory locations to which that pointer may point. The algorithm correctly handles a wide range of programming language constructs, including recursive functions, recursively generated parallelism, function pointers, structures, arrays, nested structures and arrays, pointer arithmetic, casts between different pointer types, heap and stack allocated memory, shared global variables, and thread-private global variables. We have implemented the algorithm in the SUIF compiler system and used the implementation to analyze a set of multithreaded programs written in the Cilk programming language. Our experimental results show that the analysis has good precision and converges quickly for our set of Cilk programs.
Serial Semantics With Cilk++ | InsideHPC.com The Cilk++ programming semantics are essentially extensions to what look like standard, serial C++ constructs. One can simply add ‘cilk_spawn’, ‘cilk_sync’, and replace http://insidehpc.com/2008/12/16/serial-semantics-with-cilk/
Extractions: var AKPC_IDS = ""; HPC news for supercomputing professionals insideHPC Skip to content Latest News HPC ... HPC The equivalent serial C++ program can easily be debugged and analyzed using existing development tools The serial semantics of Cilk++ programs allows CilkArts to build better tools that analyze the performance and correctness of Cilk++ programs, and these tools offer strong guarantees about the program. The serial semantics of Cilk++ provides a real advantage to program testing and quality assurance. Serial semantics provides high performance while allowing you to design your program without specifying the number of processors on which the program with execute. have Its my personal belief that Cilk++ is, at the least, an interesting attack at parallel programming. Keep in mind, with the growing core density in upcoming chip platforms, one can easily build fairly powerful SMP systems that fit on a desktop. This makes language constructs such as Cilk++ incredibly attractive to those who want to almost immediately take advantage on their newfound parallelism without extensive development pipelines. here Posted in HPC by John Leidel

This OpenCourseWare from MIT in Cambridge teaches students the theory behind programming for parallel computing . Professors Charles Leiserson, Michael Bender, Hsu Wen Jing and Dr. Bradley Kuszmaul present lectures on several topics important to the field of multithreaded programming. Subjects of study include race and determinacy detection, load balancing, synchronization and memory consistency. Later lectures cover issues relating to parallel systems on hypercubic networks. The course concentrates on programming via Cilk, a version of the C programming language that was designed for parallel processing environments. This class would be beneficial to students seeking a Doctor of Computer Science degree.
