Explain Aneka Threads with it's diagram.

 THE ANEKA ENVIRONMENT

Aneka is a development as well as a runtime environment. As a development environment, Aneka provides a collection of libraries that allow you to construct parallel applications using one of the three supported programming paradigms. Those are Task, Thread, and MapReduce. As a runtime environment, Aneka parallelizes the units of work that comprise your program. It should be noted that executing apps on Aneka requires access to a pre-installed runtime environment on a cluster. You may, however, run Aneka solo on your personal computer for development reasons.

Aneka Threads

An Aneka Thread is a piece of work that may be run on a remote computer. Unlike ordinary threads, each Aneka Thread runs in its process on the distant system. An Aneka Thread provides a comparable interface to a normal Thread and may be started and aborted in the same way. Aneka Threads, on the other hand, are simpler and do not support all of the behaviors provided by the .Net Thread class, such as thread priority management and actions like suspend and resume.

Suppose that a data warehouse consists of the four dimensions; date, spectator, location, and game, and the two measures, count and charge, where charge is the fee that a spectator pays when watching a game on a given date. Spectators may be students, adults, or seniors, with each category having its own charge rate. a) Draw a star schema diagram for the data b) Starting with the base cuboid [date; spectator; location; game], what specific OLAP operations should perform in order to list the total charge paid by student spectators at GM Place in 2004?

  b) The specific OLAP operations to be performed are: 1. Roll-up on date from date id to year. 2. Roll-up on spectator from spectator id to status. 3. Roll-up on location from location id to location name. 4. Roll-up on the game from game id to all. 5. Dice with status= “students”, location name= “GM Place”, and year=2004

Business ethics   Business ethics are moral principles that guide the way a business behaves, wrong Acting in an ethical way involves distinguishing between right and then making the right choice. Business ethics are applied or professional ethics. They may take the form of actions within written and unwritten codes of principles, and values and are determined by an organization's culture. They largely govern the decisions in the organization. However, determining what practices are ethical or not is more difficult since the lines between ethical and unethical can become blurred. The following are some of the notable definitions of business ethics Decenzo & Robbins Ethics commonly refers to a set of rules or principles that defined right and wrong conduct. Ricky W. Griffin Ethics is an individual's personal beliefs about whether a behavior, action o decision is right or wrong. Managerial ethics are the standard of behavior the guides individual managers in their work. Clara...

Explain Parallel Efficiency of MapReduce.

 PARALLEL EFFICIENCY OF MAP-REDUCE It is worth trying to figure out what is the parallel efficiency of MapReduce. Now let us assume that the data produced after the map phase is σ times the original data size D (σD), further, we assume that there are P processors which in turn perform map and reduce operations depending on which phase they are used in, so we do not have any wastage of processors. Also, the algorithm itself is assumed to do wD useful work, w is not necessarily a constant it could be D^2 or something like that, but the point is that there is some amount of useful work being done even if you have a single processor and that's wD. Now let us look at the overheads of doing the computation wD using MapReduce. After the map operation, instead of D data items, we have σD data items in P pieces, so each mapper writes data to their local disk. So, P there is some overhead associated with writing this data. Next, this data has to be read by each reducer before it can begin ...
