Concerted European Action on Magnets (CEAM)rocessing dating back several decades. MapReduce has since enjoyed widespread adoption via an open-source implementation called Hadoop, whose development was led by Yahoo (now an Apache project).Today, a vibrant software ecosystem has sprung up around Hadoop, with significant activity in both industry and academia.

VARIATION 12: Parallelmontagen,problems are independent [5], they can be tackled in parallel by different workers—threads in a processor core, cores in a multi-core processor, multiple processors in a machine, or many machines in a cluster. Intermediate results from each individual worker are then combined to yield the final output.

In the natural and physical sciences, the ability to analyze massive amounts of data may provide the key to unlocking the secrets of the cosmos or the mysteries of life.

They are brittle with respect to the natural variation found in language, and developing systems that can deal with inputs from diverse domains is very labor intensive. Furthermore, when these systems fail, they often do so catastrophically, unable to offer even a “best guess” as to what the desired analysis of the input might be.

MapReduce Basics,d very early in typical undergraduate curricula. The basic idea is to partition a large problem into smaller sub-problems. To the extent that the sub-problems are independent [5], they can be tackled in parallel by different workers—threads in a processor core, cores in a multi-core processor, multi
