What was Intel's first multicore processor?
Intel's first multicore processor was the Xeon, followed the same year (2002) by the Pentium IV. The two cores were implemented in a hyperthreading configuration, allowing two simultaneous threads when both threads were in the same process address space. Independent cores (in different address spaces) were supported starting with the Core-2 Duo. This configuration extended the hyperthreading model to include duplicating enough of the bus interface unit to allow two unrelated threads to run simultaneously.
What is the use of ht processor?
HT Processor means a processor with Hyper-Threading ability. That means that the processor would be seen as two logical cores in the computer and that the computer would give out two threads for the processor to process, hence increasing its performance.
What do you mean by real and pseudo-parallelism?
Pseudo-parallelism is the parallelism effect where a single processor creates a illusion of parallel processing by switching processes(or context) at very small intervals such that it is unnoticable to the user. This creates the effect that multiple processes(threads or programs) are running simultaneously. What actually happens is, each process is given a finite time(very small) and the process executes its instruction during this period. At the end of this period, context switching occurs and the Operating System allocates a finite time for another process. The next process may or may not be allocated the same amount of time and the time allocated to each processes depend upon their priority. On the other hand, Real parallelism applies to multi-processor(or multicore) system where each processor(or core) initiates its own sets of processes. Note that, it is possible that when a multi-core processor is performing Real Parallelism, each core might be performing Pseudo-parallelism amongst the processes(or threads) it is currently running.
Does a processor execute multiple threads at a time?
Yes it dose
How hyperthreading processor is different from other traditional processors?
A traditional processor normally isn't 100% active. There are some parts of the processor that specialise in different processes, and they can only process one thread (or task) at a time, so when it is doing one process, other parts of the processor used for other things remain idle. A hyperthreading processor is seen in operating systems as 2 CPUs so it is given 2 threads (or tasks if you like) at once. The processor then processes one thread, and uses inactive parts of the processor to process the other thread.
Can a multithread solution using multiple user level threads achieve better performance on a multiprocessor system than on a single processor system?
A multithreaded system comprising of multiple user-levelthreads cannot make use of the different processors in a multiprocessorsystem simultaneously. The operating system sees only a single processand will not schedule the different threads of the process on separateprocessors. Consequently, there is no performance benefit associatedwith executing multiple user-level threads on a multiprocessor system.
How many cores does the ps3 processor have?
1 Core 8 Threads
How many threads can core 2 duo processor execute simutaneously?
Since the core 2 duo processor has two execution units, it can execute two threads simultaneously. (If you said quad instead of duo, the answer would be four.)
How many threads can be executed on an Intel Core 2 Duo processor simultaneously?
OK. How about an INTELLIGENT answer???? Would be nice, right? First, the difference between hardware and software threads. A hardware thread refers to a physical processor's ability to run a software thread. A software thread is part of your code that you execute in a thread. That is to say, if a processor can handle two hardware threads, that means the processor can simultaneously run up to two software threads at a time. Hardware threads means physical resources. Software threads are created by your program. Regardless of how many software threads your program defines, the processor that provides two hardware threads can only execute two of them concurrently. Now, I am having big problems finding out how many hardware threads a single processor can run. In graduate school, all of the processors we modeled provided two hardware threads. If this is always true, then the Core 2 Duo sounds like it provides 4 hardware threads. Your program can create pretty much any number of software threads, but at any given time there should be no more than 4 on the chip itself. I will see if I can ask someone from the university to get a good answer and will modify my answer if I find anything out. Either way, my answer completely trumps the one that was previously posted here.
Is thread same as a function?
No. A process is composed of one or more threads. Threads can invoke any function of the process.
What is relationship between process and thread?
Process --1------------m-- Threads 1 process to many threads Bring up your Task Manager (if you are using a windows), Performance tap, you can see the number of process and the number of threads, usually the number of threads is a lot higher than the number of processes.
What are the benefits of multithreaded?
A major benefit of multi-threading in computer operating systems is that the processor and other system resources are utilized to the maximum. With single-threading, system resources may remain for periods of time.
