The Multicore Transformation Closing Statement: The multicore transformation (Ubiquity symposium)
by Walter Tichy
September 2014Multicore CPUs and GPUs have brought parallel computation within reach of any programmer. How can we put the performance potential of these machines to good use? The contributors of the symposium suggest a number of approaches, among them algorithm engineering, parallel programming languages, compilers that target both SIMD and MIMD architectures, automatic detection and repair of data races, transactional memory, automated performance tuning, and automatic parallelizers. The transition from sequential to parallel computing is now perhaps at the half-way point. Parallel programming will eventually become routine, because advances in hardware, software, and programming tools are simplifying the problems of designing and implementing parallel computations.
Making Effective Use of Multicore Systems A software perspective: The multicore transformation (Ubiquity symposium)
by Keith D. Cooper
September 2014Multicore processors dominate the commercial marketplace, with the consequence that almost all computers are now parallel computers. To take maximum advantage of multicore chips, applications and systems should take advantage ...
The Future of Synchronization on Multicores: The multicore transformation (Ubiquity symposium)
by Maurice Herlihy
September 2014Synchronization bugs such as data races and deadlocks make every programmer cringetraditional locks only provide a partial solution, while high-contention locks can easily degrade performance. Maurice Herlihy proposes replacing locks ...
The MOOC and the Genre Moment: MOOCs and technology to advance learning and learning research (Ubiquity symposium)
by Michael Feldstein
September 2014In order to determine (and shape) the long-term impact of MOOCs, we must consider not only cognitive and technological factors but also cultural ones, such as the goals of education ...
