Then what is difference between cores and logical processor ?form online articles I read number of logical processors is equal to number of total threads, But as far as i know threads are subset of processes so but what thread means if it comes to hardware perspective ? Can anyone explain ...
Logical processor Vs Cores Vs Threads. 發行項 2015/06/30 Question Tuesday, June 30, 2015 2:43 PM I am trying to understand CPU architecture deeply like cores, logical processors and vcpus. For Cores I understood that in main physical unit the separate operation unit called core and it ...
I'm having a hard time understanding hyper-threading. If the logical core doesn't actually exist, what's the point of using hyper-threading?. Thewikipediaarticle states that: For each processor core that is physically present, the operating system addresses two virtual (logical)...
A single CPU with hyper-threading appears as two logical CPUs for an operating system. In this case, the CPU is single, but the OS considers two CPUs for each core, and CPU hardware has a single set of execution resources for every CPU core. Therefore, CPU assumes as it has multiple c...
To summarize: CPU cores are physical components of your processor. CPU threads, on the other hand, represent the number of logical processing cores or, to put it a bit differently, the number of processes your CPU cores can handle.
Partitioned resources for HT operation: load buffers, store buffers, re-order buffers, small-page ITLB are statically allocated between two logical processors. Competitively-shared resource during HT operation: the reservation station, cache hierarchy, fill buffers, both DTLB0 and STLB. ...
A state machine and hardware sequencer can be used to transition the logical threads between states based on triggering events and whether or not an interruptible point has been encountered in the logical threads. The logical threads are scheduled on the physical threads to meet, for example, ...
In order to get to the current supported limit of 256 Logical processors, four processor groups are defined by Windows 2008 R2. More details can be found here: https://msdn.microsoft.com/en-us/library/dd405503%28VS.85%29.aspxThis graphic displays the hiera...

To see if limiting the number of worker threads to the number of logical cores on the computer would result in the fastest run time I implemented my own TaskScheduler. It creates one less thread than cores on the computer. The idea being that the calling thread can be used t...
