A multiprocessor system is a system in which two or more CPU (Central processing systems) are used. Input-Output processes- Any data-intensive pipeline has input, output processes where millions of bytes of data flow throughout the system. Generally, the data reading (input) process won't take much time but the process of writing data to Data Warehouses takes significant time. It involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, and have full access to all input and output devices, In other words, Symmetric Multiprocessing is a type of multiprocessing where each processor is self-scheduling. Multiprocessing helps you to increase . [7] Multiprocessing doesn't necessarily mean that a single process or task uses more than one processor simultaneously; the term parallel processing is generally used to denote that scenario. With the help of this strategy, a Keras model that was designed to run on a single-worker can seamlessly work on multiple workers with minimal code changes. The CPUs are added to the system to increase the computing speed of the system. A Linux Beowulf cluster is an example of a loosely coupled system. Multiprocessing however means true parallel execution of multiple processes using more than one processor. Applications in a multi-processing system are broken to smaller routines that run independently. Three things happen on that line: Read the value of the dictionary key (3,3) Increment the value by 1. Multi-tasking. The availability of more than one processor per system, that can execute several set of instructions in parallel is known as multiprocessing.
