When do scheduling decisions take place? \nWhen does CPU choose which process to run? Are a variety of possibilities?\n\n\nThank you ...

Processes are given a process priority, let's say from 0 (lowest) to 15 (highest). The process scheduler queues all processes according to their priority in their appropriate queue.\nThe scheduler start up with the first ready process of the highest priority queue. A process becomes ready by hardware interrupt, by time interrupt or by request (software interrupt).\nEvery process must be interruptable either by itself (waiting for an event) or by time (by the scheduler). Therefore is guaranteed that also processes with a low priority will be executed.

I'm not an expert. but Dual core processers are fairly new: AMD ATLON 64 X2, and also the PENTIUM D from INTEL. They are 2 processing cores on 1 cpu chip.

Jobs are run round robin until some fixed number of times. Then they are run only if their are no other jobs in the system.  Each process is run to a defined quanta limit in milli-seconds.\n\nA race condition occurs when the scheduling of two processes is so critical,  that the various orders of scheduling them result in different computations.\n\nA deadly embrace occurs when two processes are unknowingly waiting for resources that are held by each other and thus unavailable.\n\nThe scheduler simply does not schedule any job until all the necessary resources are available.\n\nSpecify all resources needed in advance except that the scheduler starts the job even when all of them are not immediately available. The concept here is to avoid allocating a resource to a job if there is any possibility of a deadly embrace.\n\nConstrain allocation to avoid deadly embrace.

First thing : are you using a licenced version of the operating system ?. IF yes..\n\nThe computer must be waiting for some background process to get closed before shutting down. thats why it is taking time. \n\nThere must be some program which might be not responding at the time of shutdown and the pc has to wait for it \n\nThere may be other factors also.

WHen you run the program, it is going through all the files in your whole computer, thats a lot of work. Your fan is probably heat controlled. WHen your CPU is working hard scanning, it is heating up so the fan comes on faster.

I don't see any processes that are unusual except that last one\n\nc:&#92;\n\nrun>msconfig and remove that from your startup to see if that helps

You may not totally resolve the over-allocation problem, but the project end-date will not be moved out.  This is because you have used the "slack" (ie the amount that some activities can be delayed without affecting the project end-date.) to delay certain tasks.

i have an nividia 6200 and it sucks...and if you're running a new cpu, especially with windows xp for gaming, 1st win xp takes like 256 mb ram to run by itself, so when you're buying a game, keep that in mind, ALSO...new cpus have built in things where if you don't disable the hardware first and you take it out, it will lock your cpu due to an anti-theft thing...i would take mine to the store and have the geeks do it for me, but that's just me

If it shuts off during a load or around the same time, your heat sink on your process might not be seated well and your cpu could be overheating.  Try reseating the heat sink or making sure it is in place very well.

no. not even if both cores can process the same task. but the CPU is faster when processing multiple tasks but not at the double speed. keep in mind that both cores uses one and the same resource - the system bus.

No.  It means you have two processors running at 1.66GHz (if we are talking about the Core Duo T2300 model).  What this translates to is that you have two processors that can run two different threads at the same time.  So, your anti-virus application might be running on one along with all your background processes and your photo editing and video editing software will be running on the other.  Windows will divided the processes among the two processors.  If an application is multithreaded then it is capable of running on both cores at the same time, which in effect makes it faster but there aren't many applications that are, save for Windows itself.

Set some priority of your work. ones you get that done just use computer as much as you want. But not with out getting your work done. So work 1st and Computers comes after that.

"They" reset dates because the calender is overbooked or because one party or the other is not prepared or is not present....Depending on what the case is, it may wind up dismissed if it gets delayed too long, but I'd raise cain with my lawyer for his failure to show up for a scheduled hearing.\nGood luck!

At the moment, it is doubtful if a dualcore will make much difference, since most software still needs to be rewritten to use both cores.\nOn the other hand: I have installed a dualcore about a month ago, and I do notice that when I have certain programs running which cause a heavy load on one of the cores, the other core is still available, thus keeping my system running more smoothly and allowing me to do more with it at the same time.

The problem with calculating running time of an algorithm is that there are so many variables which affect running time (far beyond just cpu speed and RAM size).  It is impossible to come up with a accurate calculation from these variables.\n\nBig O is useful because it calculates relative effeciency, regardless of hardware outside conditions, and size of test data.\n\nIn order to come up with actual numbers, the ONLY accurate way is to actually run the algorithm and time it.

You probably (very likely) have a virus. It's disabled your Task Manager so you can't see its process running.\n\nInstall anti-virus software immediately, and be more careful next time.

Depends on what software you are using, what speed and if you are doing anything in the background. It's probably stuck but give it some time unless you have been waiting for an hr or more then give up on it.
