What is different between SIMD multiprocessing and MIMD multiprocessing?

SIMD Defined
- The SIMD architecture performs an identical action simultaneously on multiple data pieces. This single action can include retrieving, calculating or storing information. An example is retrieving a lot of different files at the same time. Processors with local memory containing different data execute the same instruction in a synchronized fashion, with inter-processor communication for shift allocation.
MIMD Defined
- The MIMD architecture performs multiple different actions simultaneously on multiple data pieces. An example is the performance of various mathematical calculations such as addition and multiplication simultaneously in order to solve a complex math problem with many separate components. MIMD computing may or may not be synchronized and is increasing more commonly than SIMD computing.

What is the difference between parallel computing and parallel processing?
Parallel processsing ranges from instruction-level parallelism e.g. superscalar and VLIW to message-passing MIMD also called multicomputer, and also includes SIMD e.g. vector and array processing. Multiprocessing is specifically task parallelism, and is by definition shared-memory MIMD with multiple processor cores, sometimes multiple sockets.
What is the difference between SIMD and MIMD?
SIMD (single instruction, multiple data) describes multiple processing elements that work on the dame operation on multiple data points. MIMD (multiple instruction, multiple data) is the number of processors that function independently.
What has the author Matthew D Levin written?
Matthew D. Levin has written: 'Parallel algorithms for SIMD and MIMD computers'
What is flynn's taxonomy of parallel architecture?
Flynn's taxonomy is used to categorize computer architectures. Considers the number of processors and the number of data paths incorporated into an architecture. The fours combinations of processors and data path are: SISD( Single instruction, single data stream) MISD( Multiple instructions, single data stream) SIMD (Single instructions, multiple data streams) MIMD( Multiple instructions, multiple data streams)
Static versus dynamic network in SIMD interconnection network?
Static- Links between two processor are passive & dedicated buses cannot be reconfigured for direct connection to other processor.Dynamic- It can be reconfigured by setting the n/w active switching element.with different classes i.e single stage & multistage.
Is a process that allows the CPU to receive a single instruction and then execute it on multiple pieces of data rather than receiving the same instruction each time each piece of data is received?
"SIMD, which stands for 'single instruction, multiple data,' is a process that allows the CPU to receive a single instruction and then execute it on multiple pieces of data rather than receiving the same instruction each time each piece of data is received."(Pg. 434, A+ Guide to Managing and Maintaining Your PC)
What does the acronym SSE stand for?
There are many different things that use the abbreviation SSE. In computing, it can stand for Streaming SIMD Extensions, server-sent events, or simple sharing extensions. It can also be used for supply-side economics and is also an energy company in the UK.
What are multi vector and SIMD computers?
(Single instruction, Multiple Data) A process that allows the CPU to execute a single instruction simultaneously on multiple peices of data, rather than by repetitive looping.
What is array processor and what is the role of attached array processor?
aray processor is a processor that performs computations on large arrays of data. It is of two types: (1) attached array processor. (2)SIMD array processor.
What does MMX stand for?
it stands for Multimedia extension. MMX is a technology by using which a computer can accept an input or give an output in the form of text, image or sound. MMX enabled microprocessors employ SIMD (Single Instruction Multiple Data) technique of data processing.
What is Shuffle Exchange Network?
it is an interconnection network that is designed for connection between processors.this model works whit 2 functions:shuffle and exchange. shuffle function: shuffle( sn-1,sn-2,...,s0)= (sn-2,...,s0,sn-1) exchange function: exchange (sn-1,sn-2,...,s0)=(sn-1,sn-2,...,~s0) for example,we can sum integers whit shuffle exchange network with this algorithm: summation(SIMD-PS) begin for i=1 to log n do for all pj where 0<= j <= n do shuffle aj bj := aj exchange bj aj := aj+bj end for end for end this model of interconnection networks is SIMD(single instruction multiple data) from Flynn architecture and in useful for parallel algorithms.
What is the difference between distributed and parallel processing operating system?
1) Distributed Operating systems are also referred to as Loosely Coupled systems whereas parallel processin g systems are referred to as tightly coupled systems. 2) A Loosley coupled system is one in which the processors do not share memory and each processor has its own local memory whereas in a tightly coupled system there is a single systemwide primary memory shared by all the processors. 3) The processors of distributed operating systems can be placed far away from each other to cover a wider geographic area which is not the case with parallel processing systems. 4) The no. of processors that can be usefully deployed is very small in a parallel processing operating system whereas for a ditributed operating system a larger no. of processors can be usefully deployed....... 5)globle clock is used for controlling simd n mimd in parallel..... .in distributed no any global colck present in this synchronization algorithms are used 6)in the distributed operating system there is an unpredictable communication delays between processors whereas the processors in the parallel processing system share over an interconnection network
