Redundacy
[edit]This article seems entirely redundant with Multiprocessing. Even if there is some info currently not in that article the topic shouldn't be split as significant overlap would result. --Zac67 (talk) 09:41, 25 November 2018 (UTC)
This article has been proposed to delete because redundant with "multiprocessing".
My opinion is different for two reasons:
1) all encyclopedias describe the terms "multiprocessor" and "multiprocessing" with separate entries (because they are two different concepts) [1][2][3][4].
The question is: why in Wikipedia no ?!
2) - The information described in the "multiprocessor system architectures", ie how the multiprocessors are connected, are not described in the "multiprocessing" entry and nowhere else in the Wiki and these would have been lost.
(only for knowledge I am a super expert in computer design with almost thirty patents in particular in this field (search with google "Zulian Ferruccio patent" and for instance:
http://www.freepatentsonline.com/result.html?query_txt=Zulian+Ferruccio&sort=relevance&srch=top&search= https://patents.google.com/patent/US6314484 https://patents.google.com/patent/EP0608663A1/ru http://patent.ipexl.com/inventor/Zulian_Ferruccio_1.html https://patents.google.com/patent/US4928224 https://patents.google.com/patent/US5870560 https://patents.google.com/patent/EP0098494A2/en https://patents.google.com/patent/EP0396940B1/en https://patents.google.com/patent/EP0033915A1
... etc...)

- While I absolutely agree that there are significant differences I don't think it's wise to create a forked article here. The current content can very well be incorporated into Multiprocessing, rather than abandoning that article and creating a new one here with a very narrow perspective. --Zac67 (talk) 14:31, 25 November 2018 (UTC)
multiprocessor
[edit]"Multiprocessor is a system with more than one processor"
Multiprocessor applications are:
- fault tolerance
- multiprocessing
- parallel processing
that is, not just for multiprocessing
- In fault tolerance systems, all processors perform the same task and the results are compared to each other (for instance, triple redundancy for the Aircraft computer)
- In multiprocessing each processor usually operates on a common database (data sharing)
- In parallel processing, each processor operates on separate data
- A multi-core processor is an integrated circuit (IC) to which two or more processors are connected for improved performance, reduced power consumption for multiprocessing but above all for multithreading which is a form of parallel processing.
Another form of parallel processing is given by superscalar processors that have more than one execution unit.
"multiprocessor system architecture" describes how a multiprocessor system is connected, regardless of the type of system that can be for fault tolerance, multiprocessing and parallel processing and must be described in a dedicated article or in multiprocessor description article not in multiprocessing!! this is a sub-case of multiprocessor.
