Some compilers in this category provide special constructs or extensions to allow programmers to directly specify operations to be performed in parallel (e.g., DO FOR ALL statements in the version of FORTRAN used on the ILLIAC IV, which was a SIMD multiprocessing supercomputer).SIMD multiprocessing finds wide use in certain domains such as computer simulation, but is of little use in general-purpose desktop and business computing environments.[citation needed] [edit] MISD multiprocessing Main article: MISD MISD multiprocessing offers mainly the advantage of redundancy, since multiple processing units perform the same tasks on the same data, reducing the chances of incorrect results if one of the units fails.However, a drawback to this architecture is that a large part of the system falls idle when programs or system tasks are executed that cannot be divided into units that can be processed in parallel.

Computer science previously formed an option in group 5 of the Diploma Programme curriculum but now lies within group 4.

As such, it is regarded as an experimental science, alongside biology, chemistry, design technology, physics and environmental systems and societies.

You might want to look into some functional languages such as haskell and lisp which would get past these problems but are rarely used for writing games.

Though there is a great book on writing games in lisp.

It is used in array processors and is implemented in fault tolerant machines.

Another example of MISD is pipelined image processing where every image pixel is piped through several hardware units performing several steps of image transformation.Previous extended essay were mostly to do with security however that doesn't appeal to me i was thinking of something along the lines of video games and multiprocessors. Previous extended essay were mostly to do with security however that doesn't appeal to me i was thinking of something along the lines of video games and multiprocessors. thank you The sega saturn was a multi processor system that rarely used the second processor. But there is a problem with imperative languages and splitting code to run on multi processors.I'm not sure what the utilisation of a 7 core PS3 looks like, but I imagine it is very rarely close to 100%.A single instruction stream directs the operation of multiple processing units to perform the same manipulations simultaneously on potentially large amounts of data.For certain types of computing applications, this type of architecture can produce enormous increases in performance, in terms of the elapsed time required to complete a given task.This Lib Guide (adapted with thanks from Zurich International School's Kevin Browning and The American School of Madrid) was created by Kathy Fester and Roxy Yuen Concordian International School, Bangkok The content is shared under a Creative Commons Attribuition-Noncommerical license.Feel free to reuse any information found on this guide.One component of the International Baccalaureate® (IB) Diploma Programme (DP) core, the extended essay is mandatory for all students.
