Computers / No AMD Zen 'SMT' issue with Windows Scheduler BUT...
« Last post by snadge on 16 March 2017, 17:43:26 »
As some of you may have been aware, there was some concern that AMD Ryzen chips may have had a thread scheduler issue... that is to say that it was thought that threads of data were being handed off as 0,1,2,3,4 etc to the CPU instead of 0,2,4,6 - 1,3,5,7 etc - if they are not off-loaded every 2nd CPU/Thread then you could end up with an application that has only 2 threads being processed by 2 logical cores  on 1 physical core...this is not as good as each thread being processed by a dedicated core,, so to ensure this the windows scheduler hands off threads in a manner that they will land on dedicated cores before it runs out and assigns them as multi-threaded workloads

Trying to ascertain whats happening has lead to another discovery, whilst AMD has again put cores in groups of two complexes, it would seem that the communication of cores between groups take 100ns longer than cores within the same complex

Oh I didn't hear about these? It's really a big problem with the Switch? Maybe they rushed the release.

yeah they have, thats what everyone is saying, especially for the shortage of games, apart from Zelda you can only get about 3-5 other "crap" games

AMD have probably launched their Ryzen too soon as well.. their problems arent great and can be fixed with BIOS & GAME updates - that said it was recently shown that AMD's SMT (Simultaneous Multi-Threading) handling seems to be working as expected in some peoples tests (as this was initially expected to be the cause with the windows scheduler not being optimised for AMD SMT which is same as Intels Hyper-Threading)

I use Windows 10.

great OS but too much telemetry for my liking.... its constantly logging every single thing that happens on the PC, this causes write amplification on SSD's, this is a combo of Telemetry for Windows Feedback, Logging for windows crashes, live tiles/cortana constantly syncing online and web browsers such as Firefox have quite a bit of write amplification due to writing cookies and database for crashes every 15 seconds.
