HP 4510S laptop. has dual core processor but is only running one half of it.

This system is running on Win 7 32bit. If I upgraded to W7-64 bit would the system then use both halves of the processor?

I use BELARC advisor which lists all hardware, SW on my system. It also tells me what processors I have, memory, etc. It will also tell me if I have a dual or single core processor and whether it is running both cores or only one. My gateway NV50 is running Win 7-64 bit and BELARC tells me how it is working on both cores. But my wifes LT which is an HP has win 7-32 bit for an OS and Belarc advises that it is only running one core. That is why I asked the question. I am upgrading the HD from 250 to 750 gb and maxing out her memory. Maybe then she will quit complaining about how slow it works.

HT2534 My iPhone has 2 email addresses but I only need one. How do I erase the other email address and simply use my main one. The other account is connected to another device so I do not need both addresses

Hi,
My mom and I have Apple devices (she has an iPhone 3G, and I have an iPod touch) .. I noticed that some of her apps require my password to my Apple ID and some of the other apps require her password for her Apple ID. When she first bought the phone, I used my Apple ID to download those apps since she was new to the Apple community. However, whenever she gets new updates, those apps still need my password (even though I've erased my account from her phone). Is there any possible way for her to update all of her apps using only one ID (hers) instead of using mine? It's very troublesome and I don't want to give her my password because she'll only end up losing it.
If anyone can answer this question, I'd greatly appreciate it.

Sorry for the delayed response, yes i want to use my university account when replying to all emails. Note i just discovered something, when i forward my university email to my icloud account and than responded from either my imac of my macbook air (i.e. in icloud) it automatically goes to my university account in the "from" space (good news!!!). That is just what i wanted, . While that is the good news, the bad news is that my iphone and ipad still treat this email as being from icloud even though it is forwarded (redirected) from my university account. That is when i respond to an email (or for that matter create a new email in my icloud account) it automatically lists the icloud account as the "from" account and i have to go in and manually modify it. So i am 50% there to solving my problem (i.e. actually did nothing the systems just worked well) but i still need to figure out a way to make this happen on my ipad and iphone. Any help or suggestions, note the default button in the iphone and ipad for email work differently than the default in the composition menu of the imac or macair.

How to use Real time execution trace toolkit with Dual-core processor??

hi there
the situation as follows:
i have a computer (PC and Laptop) types with Dual-core processors, and am trying to do simulation using Multi-core technology and based on different simulation scenarios...starting from sequantial processing,.......Piple lining processing strategy. so that i can differentiate the time delay between those types of processing based on (Using 1 processor then dual-core processor Computers)
my question is: As i read through Ni's white papers i saw many notes refer to Real-time execution trace toolkit to investigate the (processing-time , etc) of multi-core processors in processing diffenent algorithms. My algorithms are to be run on 1 computer with dual-core processor BUT, not in real time environments, that is ( No hardware to be connected to my pc) only algorithms running on my pc....
So, is it possible to use Real time execution trace toolkit or anyother tools in LabVIEW to show processing-delays and/or anyother timing critical issues without using my application for real- time hardware.???
in other words: how to use Real time execution trace toolkit in non-hardware and/or real-time scenarios???
please help me in this.
Any suggestion, comments, feedback.....is absolutely highly appreciated
thanks a lot in advance

Hey,
The Realtime Execution Trace Toolkit only works for NI RT Targets.
But you can use the Desktop Execution Trace Toolkit, just search for it under ni.com.

Labview 7.1 and Dual Core Processors

Hi,
I was wondering if anyone has encountered any problems using Labview
7.1 and the newer dual-core processors. I have a Dell Dimension DXPO51,
2.8 GHz Pentium D with 1 GB ram. There is NO virus software or any
other non-essential programs running in the background. The computer is
totally dedicated to controlling a machine.
Other NI boards installed: PCI-6221 for analog inputs, PCI-6602 for
reading encoders, PCI-7352 Motion Control board to control 2 motors.
The problem:
Periodically when I start my program, it locks up and I get the "Tell
Microsoft about this problem..." screen. After it exits out of Labview
and I restart, the Run arrow is not broken but the program will not run
until I make a change on the block diagram. Then I can run again.
Doesn't happen all the time, doesn't happen after running after a
certain amount of time, doesn't happen after a particular change is
made (i.e. adding case statements, adding an event, etc.). In other
words, totally random.
I have tried totally uninstalling ALL National Instruments software,
including cleaning the registry, and re-installing everything. Didn't
help.
The machine will be shipping with the executable file only but I'm still leary of problems arising due to this issue.
Any help or suggestions of things to try would be appreciated.
Thanks,
Teri

Hi Teri,
I've seen scattered reports of users having trouble with dual-processor
machines with earlier versions of LabVIEW, though I'm not aware of
verified solutions in those cases. The dual-processor operation
should be completely transparent to LabVIEW, although I know XP has had
some difficulties in providing the abstraction correctly. A
workaround that has been successful in the past is to set the processor
affinity for LabVIEW to a single processor. This should eliminate
the dual-processor nature of the system from consideration. If
the problem still recurs after that, then the issue stems from another
source and we can investigate further. Does it show this behavior
with any program (or just by opening the LabVIEW environment)?
How often does this occur (10%, 50% of the time)?
Cheers,

Uneven Core usage on dual core processor

Hi there
I noticed today whilst doing some video encoding (.TS files to .MP4) that my Mac Mini is not spreading the load over both of the cores in my dual core processor. Whilst Core 1 is showing nearly 100% Core 2 is hardly being used. Also I noticed that when the load on Core 1 dips then Core 2 will peak but as soon as the load goes back to Core 1 it will equally dip on Core 2 so essentially in Activity Monitor it looks like the core usage is a negative image of each other. The total CPU usage never peaked above 54%.
Could this an indication of a failing CPU or is it a case of poor core management? The software I've been using is VLC Player and also iMagiConverter.
Cheers
Jonty

What I don't understand is why software developers make software (especially video encoding that is all about CPU number crunching) that only utilises 50% of the CPU resources!
There are any number of possible reasons, from an application using a cross-platform code base that doesn't lend itself well to mulitiprocessor optimization for a particular platform, to inexperienced programmers who don't well understand programming for parallel threads, to developers who just want to crank out an application as quickly as they can (iMagiConverter seems to sort of fall into that category, given the number of applications of a similar nature that the "company" has produced). You'd have to get involved in the project development to know for sure.
Regards.

Jdeveloper dual core processor performance problem

I have a dual core 2.4 ghz processor and 2 gig of ram and Im running Jdevloper 9.0.5.2 and my performace is terrible. Other developers in the company have non-dual core processors and they can start up in debug mode using the Jdeveloper embedded oc4j our application in 10 seconds where it takes me 4 min!!!!! It is a struts,ejb web application. Is there anything I can do to help in debug mode??? cheers.

Hi Bernard,
Which version of McAfee are you using?
On my (personal) laptop, I'm using McAfee VirusScan 9.0.10. I don't frequently run JDeveloper on this laptop, but when I do, it's not experiencing signficant startup delays (it's a very low power machine: PIII 650 512Mb)
McAfee VirusScan seems to have very few configuration options (noticably different from Norton, which I use on my corporate desktop machine). I specifically remember changing the "File Types to Scan" option to "Program files and documents only". You can get to this by right clicking the "M" notification area icon, VirusScan->Options menu, Advanced button on the ActiveShield page.
In Norton, I think I have it configured so that it only scans files on write rather than on read. I also exclude directories which contain jdeveloper installs or other large Java apps (although scanning only on write elliminates most of the performance problems anyway and still leaves your system reasonably secure).
The easiest way to convince your MIS dept that the virus checker is the source of your problems might be if you ask them to allow you to turn it off in order to test the difference it makes to performance. It's a reasonable request to make if you're trying to elliminate possible causes for the slowdown (from the description you gave, it does sound like the AV upgrade is the first place I'd start looking).
If the virus checker is the source of your problems, you'll probably be seeing massive slowness in most large Java applications that have a large number of JARs on their classpath.
Thanks,
Brian

Toshiba Sattelitte L550D, AMD dual core processor M520, Firefox 3.6 works fine; any later version produces only server not fond for any URL; any one have a fix?

Forgot to mention op system is Windows 7 64 bit; 4 gig memory and a 320 gig 5400 rpm (slow) SATA drive. Have tried Pale Moon with the same result although its site shows the AMD Turion II dual core processor as supported

Yes, the question was poster from my desktop machine which is set to dual boot both windows 7 and Xp. I regularly run spybot scans but I'll try all the others you mentioned.
Thanks

Using the 2nd of a dual core processor

I have a dual core processor laptop and currently it isn't using the 2nd one at the moment. The first one is full and I am getting messages saying I have no memory space. How can I use the 2nd processor?

We need to know your full model number, like Satellite A215-S7437, and your Part Number, like PSAFGU-00L002. You can find this information on the Toshiba label on the bottom of your computer. Also, we need your operating system version, like Windows 7 32bit.
In addition, give us the exact error message that you are getting. Do not paraphrase, spelling and syntax are important. A screen shot of the error message would be best.
However, I would mention that your processor(s), your available system RAM (Random Access Memory), and the available space on your HDD (Hard Disk Drive), are three completely different things.

Turning on Virtualization in Compaq/HP Presario C500 with Dual Core processor

Hoping someone can help me out.
Running a Compaq Presario C500 laptop with the Dual Core processor. Intel's site says the processor supports virtualization.
However, in the F.24 A Phoenix BIOS setup (pressing F10 on Startup), there's no option to turn on Intel Virtualization Technology on any of the Tabs. Tried downgrading the BIOS to F.14A -- as the description says; "Adds item to Setup utility (F10) to enable/disable Intel Processor Virtualization Technology."
However, when I startup, press F10 -- there's no option for turning this on.
Is there another place to go -- other than the F10 setup area of the BIOS -- to turn on Virtualization Technology?
If an expert out there can help, it would be very appreciated!

Problem with dual core processors: 50% ressources are not used.

Hello all,
I have noticed, that the java app cannot get normally more than 50% of the system ressources. I use different threads in my application, but the app still does't achieve 100% of system power. Max 50-60%.
If I run two processes, I get 100%, but I can't share memory space between this two process. Or I can?
What is the best way to write an application, that can use 100%, in other words, full power of dual core processors.
Thanks in advance.

Try thread.setPriority() method. I am making guess
and any comments
from experts on this method will be highly
acknowledged.Yeah. Don't do that, it's a bad idea.
Back to the original post, there are two reasons this can be happening.
1) Your code is not efficient multi-threading wise. If you are for example running two thread that are in theory parallel but in actual fact provide linear execution so that one is almost blocked by the other then multiple threads and multiple cores will underutilized. It's hard to speculate further on this without seeing your code.
2) The OS. First of all there is the issue of how the oS shares up the processor between processes. This varies and may or may not be configurable. The bottom line on this point is that your OS may be capping the utilization of the processor by process. Again there's not enough information give by you to expand on this point. The second OS issue regards how the OS deals with multi-core. Just because you have a multicore processor does not mean that your OS automatically can take advantage of it.

Is a Pentium(R) Dual-Core processor good enough for Adobe Premiere Pro?

is a Pentium(R) Dual-Core processor good enough for Adobe Premiere Pro? Under system requirements, Adobe listed Intel Core Duo...not sure if this is just as good?

Hi Brian,
Good question. Keep in mind that these are minimum system requirements. I have not had a core 2 duo for some time, but I recall that the performance was not that good at that time, and this was CS5.5, or so. If you are going to use this machine, be sure to work at lower playback resolutions until you can afford a more powerful computer.
Video editors typically have more powerful systems than the minimum system requirements. Check our hardware forum for details: Hardware Forum

Parallelism in oracle using only one dual-core processor

Hi, is usefull or could i use parallel execution in oracle using only one dual core processor?
Can someone explain me why?

Hi
To take advantage of parallel processing you need enough resources (mainly CPU and I/O). If you run serially and the bottleneck is the CPU, then parallel processing might help. On the contrary, if the bottleneck is located in the I/O sub-system, throwing more CPU to it would not make things better. So, it's a question of balance between the CPU and I/O resources you have.

Why is it that the new macbook pro processor upgrade option only offers up to 2.8 Ghz with Intel Dual Core i7, when back in Sep 12 I bought a 2.9 Ghz Intel Dual Core i7 Macbook, is the new one tuned to go much faster anyway?

Why is it that the new Macbook Pro processor upgrade option only offers up to 2.8 Ghz boosting to 3.3 Ghz with Intel Dual Core i7, when back in Sep 12 I bought a 2.9 Ghz boosting to 3.6 Ghz Intel Dual Core i7 Macbook, is the new one tuned somehow to go much faster anyway, or will the new one be slower in fact? Or does the solid state drive compensate for the lack of increased processor capacity?

The CPU's come from different Intel 'families'. The older ones are 'Ivy Bridge' and the newer ones are 'Haswell'. Numbers alone will not determine the efficiency of CPU.
Ciao.
