What is scalable parallel computer architecture?
Parallel computing is a type of computing architecture in which several processors simultaneously execute multiple, smaller calculations broken down from an overall larger, complex problem.
What is MIMD in parallel processing?
MIMD stands for ‘Multiple Instruction and Multiple Data Stream’. In this organization, all processors in a parallel computer can execute different instructions and operate on various data at the same time.
What are the types of MIMD architectures?
There are two types of MIMD architectures: distributed memory MIMD architecture, and shared memory MIMD architecture.

What are parallel computer models?
Parallel computers use VLSI chips to fabricate processor arrays, memory arrays and large-scale switching networks. Nowadays, VLSI technologies are 2-dimensional. The size of a VLSI chip is proportional to the amount of storage (memory) space available in that chip.
How do SIMD and MIMD differ as parallel processing architectures?
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.
What are MIMD architectures and explain their features?
In computing, MIMD (multiple instruction, multiple data) is a technique employed to achieve parallelism. Machines using MIMD have a number of processors that function asynchronously and independently. At any time, different processors may be executing different instructions on different pieces of data.
What is SIMD and MIMD?
What is an HPC processor?
High performance computing (HPC) is the ability to process data and perform complex calculations at high speeds. To put it into perspective, a laptop or desktop with a 3 GHz processor can perform around 3 billion calculations per second.
Which is the type of microcomputer memory?
In microcomputer we have two types of memory 1) Volatile and 2) Non-volatile. Volatile: Memory that stores data for short time of period till the light is switch on. Non-Volatile: Memory that stores data permanently. RAM (Random Access Memory): RAM is also known as Physical memory.
What are the different hardware architectures for parallel processing?
Hardware architecture of parallel computing –
- Single-instruction, single-data (SISD) systems.
- Single-instruction, multiple-data (SIMD) systems.
- Multiple-instruction, single-data (MISD) systems.
- Multiple-instruction, multiple-data (MIMD) systems.
What are the characteristics of a MIMD architecture?
MIMD architecture includes processors that operate independently and asynchronously. Various processors may be carrying out various instructions at any time on various pieces of data. There are two types of MIMD architecture: Shared Memory MIMD architecture and Distributed Memory MIMD architecture. Shared Memory MIMD architecture characteristics:
How does distributed memory work in a MIMD machine?
In distributed memory MIMD machines, each processor has its own individual memory location. Each processor has no direct knowledge about other processor’s memory. For data to be shared, it must be passed from one processor to another as a message.
What does MIMD stand for in Computer Science?
In computing, MIMD ( multiple instruction, multiple data) is a technique employed to achieve parallelism. Machines using MIMD have a number of processors that function asynchronously and independently. At any time, different processors may be executing different instructions on different pieces of data.
What does multiple instruction, multiple data ( MIMD ) mean?
Multiple Instruction, Multiple Data (MIMD) refers to a parallel architecture, which is probably the most basic, but most familiar type of parallel processor. Its key objective is to achieve parallelism.
