MAMF: I see no point in combining the general and specific articles related to multi-threading. Having browsed most of the links I feel the current setup is better.

:I agree indeed, but then this page needs to be revamped, as it was originally intended to only cover the Hardware multithreading, thus the previous name before the renaming. As of now, if somebody looks for software multithreading information, he will get very confused by what the page says which is specific to hardware multithreading. I'd suggest to move the detailed hardware material to a separate page, and link to there from here. [[Author:SamuelThibault|Samuel Thibault]] Fri, 18 Sep 2009 13:47:17 +0200

''"Execution times of a single-thread are not improved but can be degraded."'' I strongly doubt of this. If there is really only one thread, then it can use the whole computing power and caches for itself. When running two threads that do not share data, that's another story of course [[Author:SamuelThibault|Samuel Thibault]] 16:27, 1 December 2008 (UTC)

:::Errr, no, looking at the list again, running two threads is the point of the previous item in the list: ''"Multiple threads can interfere with each other when sharing hardware resources such as caches or translation lookaside buffers (TLBs)."'', here "multiple threads" does not necessarily mean "multiple threads of the same process". <small><span class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:SamuelThibault|SamuelThibault]] ([[User talk:SamuelThibault|talk]] • [[Special:Contributions/SamuelThibault|contribs]]) 13:49, 1 January 2009 (UTC)</span></small><!-- Template:Unsigned --> <!--Autosigned by SineBot-->

Mmm, I'm tempted to drop the reference to multithreaded cryptography. If we let that one in, then I'm afraid we'll get a big bunch of "multithreaded this" and "multithreaded that", as multithreading is potentially applied to any algorithm...

== Multithreading vs SMT? ==

Can somebody explain the differences between this article and [[Simultaneous Multithreading]]? As these two articles are written now, it looks that overlap is huge, and it is tempting to merge this article into SMT (which is much more specific and universally recognizable term than 'Multithreading'). [[User:Ipsign|Ipsign]] ([[User talk:Ipsign|talk]]) 05:09, 11 October 2010 (UTC)

: As this article is trying to explain, SMT is a sub-type of MT. As such, this article covers other types of MT. There are also errors in the [[Simultaneous multithreading]] article. I don't agree that SMT is a more widely recognized term. If anything, the Intel Marketing trademark 'Hyperthreading' is more widely recognized. [[User:Dyl|Dyl]] ([[User talk:Dyl|talk]]) 03:48, 12 October 2010 (UTC)

:: Hyperthreading is (arguably) one of SMT implementations, so I would argue they should belong to the same article (I dont care if it is named SMT or Hyperthreading). And when somebody searches for 'multithreading', I don't think they expect to see this article (more likely, it is about multithreading in software, which is currently under [[Thread (computer science)]]). In addition, most of material in current [[Multithreading]] article is completely unsourced. I will be arguing complete rewrite and/or merge on these grounds. [[User:Ipsign|Ipsign]] ([[User talk:Ipsign|talk]]) 14:03, 17 October 2010 (UTC)

: You want to merge multithreading because it is completely unsourced? Where's the policy that mandates such action? Also, where would you merge this article too? [[User:Rilak|Rilak]] ([[User talk:Rilak|talk]]) 06:59, 29 October 2010 (UTC)

== Rewrite ==

Line 69 ⟶ 57:

:: "Are you asking what implicit multithreading is?" - no, I'm trying to figure out ''where in the current [[Multithreading (computer architecture)]] article it is mentioned?'' And if it is not in the article, do you think it belongs there? [[User:Ipsign|Ipsign]] ([[User talk:Ipsign|talk]]) 08:44, 2 November 2010 (UTC)

:: Actually, now (after going through several dozens of DAB links) I tend to withdraw my objection to the article name, though it seems that it will need to be heavily expanded to cover this whole topic. [[User:Ipsign|Ipsign]] ([[User talk:Ipsign|talk]]) 12:38, 3 November 2010 (UTC)

::: I scrolled through the article and I think that it only covers what the ACM paper calls explicit multithreading. I don't think that we need to cover implicit multithreading here as those architectures are not generally categorized as multithreading.

== System thread ==

Line 75 ⟶ 64:

Is there a name for this type of multithreading which was invisible to most users? The arrangement meant single threaded processes ran better than they might otherwise because many overheads were dealt with in parallel in the background. Do any processors nowadays do this business of having a second stream deal with such overheads, or does it happen in practice anyway when not all available hardware threads are being used by programs?

== External links modified (February 2018) ==

Hello fellow Wikipedians,

I have just modified one external link on [[Multithreading (computer architecture)]]. Please take a moment to review [[special:diff/824577468|my edit]]. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit [[User:Cyberpower678/FaQs#InternetArchiveBot|this simple FaQ]] for additional information. I made the following changes:

*Added archive https://web.archive.org/web/20100821074918/http://cache-www.intel.com/cd/00/00/01/77/17705_htt_user_guide.pdf to http://cache-www.intel.com/cd/00/00/01/77/17705_htt_user_guide.pdf
