Multiprocessor vs. Multicomputer: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on January 23, 2024
Multiprocessor is a system with multiple CPUs sharing a single memory and OS. Multicomputer is a network of independent computers, each with its own memory and OS.
Key Differences
Multiprocessor systems are designed with multiple CPUs integrated into a single machine, sharing common resources like memory and operating system. Multicomputer systems, however, consist of several independent computers, each with their own CPU, memory, and operating system, connected through a network.
In multiprocessor setups, CPUs share resources such as memory and I/O, facilitating efficient communication and task management within a single system. In contrast, multicomputer systems operate independently, with each computer managing its own resources, and communication between computers happens over a network.
Multiprocessor environments excel in tasks that require tightly coupled processing, offering high-speed data processing within a single system. Multicomputer networks, on the other hand, are more scalable, as adding more computers to the network can enhance overall computational power.
Multiprocessor systems, due to their shared architecture, can be less fault-tolerant, as a single point of failure can affect the entire system. Multicomputer systems offer higher fault tolerance, as each computer operates independently, ensuring the network can sustain individual computer failures.
Multiprocessor systems are often used in environments where high-speed, parallel processing is crucial, like scientific computing. Multicomputer systems are more common in distributed computing scenarios, like cloud services, where scalability and fault tolerance are key.
