Explanation / Answer

11.As we know that SIMD and MIMD are two different parallel computing architectures that use multiple processors and sometimes multiple computers to process data.Single Instruction Multiple Data (SIMD) means that all parallel units share the same instruction, but they carry it out on different data elements.Both two have major differences SIMD stands for Single Instruction stream Multiple Data stream, while MIMD stands for Multiple Instruction stream Multiple Data stream.

Differences Between SIMD and MIMD

Parallel computing works by dividing large problems into smaller problems which are then solved at the same time. SIMD and MIMD are two different parallel computing architectures that use multiple processors and sometimes multiple computers to process data. SIMD stands for Single Instruction stream Multiple Data stream, while MIMD stands for Multiple Instruction stream Multiple Data stream. SIMD and MIMD architectures permform similar basic functions, but they differ both practically and technically.

We can define SIMD as:

The SIMD architecture performs a single, identical action simultaneously on multiple data pieces, including retrieving, calculating or storing information.

We can define MIMD as:

The MIMD architecture performs multiple actions simultaneously on numerous data pieces.

Example for SMID:

One example is retrieving multiple 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.

Example for MIMD:

One example is performing various mathematical calculations -- such as addition and multiplication -- simultaneously in order to solve a complex math problem with many separate components.

In SIMD processor, we have a global controller unit with many processors and all the processor does the same thing. SIMD is limited to only few applications. In the cases like where we don't have identical but many independent tasks then we use MIMD architecture.

I think this answer will helps you.
