16 Questions
Define Shared Memory Architecture.
Shared Memory Architecture refers to a parallel computing architecture where multiple processors share the main memory.
What does MPMD stand for in parallel computing?
MPMD stands for Multiple Program Multiple Data.
Explain the concept of SPMD.
SPMD stands for Single Program Multiple Data. In SPMD, all processors execute the same program but on different data sets.
What is a Task in the context of parallel computing?
A Task is a logically discrete section of computational work, typically a program or program-like set of instructions.
Differentiate between Parallel Task and Serial Execution.
A Parallel Task can be executed by multiple processors simultaneously, while Serial Execution involves executing a program sequentially, one statement at a time.
Explain the life cycle of a Process in parallel computing.
A Process has a life cycle consisting of execution, creation, and termination phases. Processes can create new procedures, leading to a chain of process generation.
Which type of parallel computer architecture is characterized by a single data stream fed into multiple processing units, each operating independently via independent instruction streams?
Multiple Instruction, Single Data (MISD)
Which of the following types of parallel computer architecture is exemplified by Connection Machine CM-2 and Maspar MP-1?
Single Instruction, Multiple Data (SIMD)
In Flynn's Classical Taxonomy, which category of parallel computing is considered the most common type among modern computers?
Multiple Instruction, Multiple Data (MIMD)
What is a key characteristic of SIMD architecture?
Lockstep operation
The IBM 9000 and Cray C90 are examples of which type of parallel computer architecture?
Single Instruction, Multiple Data (SIMD)
What distinguishes MISD architecture from the other types of parallel computer architectures?
Single data stream into multiple processing units
Which type of architecture involves multiple processing units operating on different data streams using independent instruction streams?
Multiple Instruction, Multiple Data (MIMD)
What is a common example of a system that follows MISD organization and architecture?
CarnegieMellon C.mmp computer
'Most modern computers fall into this category' refers to which type of parallel computer architecture?
'Multiple Instruction, Multiple Data (MIMD)'
What makes Processor Arrays and Vector Pipelines suitable for specialized problems like image processing?
Deterministic execution and synchronous operation
Learn about the SPMD (Single Program Multiple Data) and MPMD (Multiple Program Multiple Data) programming models in the context of parallel programming using Python. Understand how tasks can execute only specific portions of a program based on branching logic. Explore how different tasks can work with varying data sets.
