Multiprocessor machines - making JVM only use one processor

When running java with a multiprocessor machine, is there a command line switch of some sort that restricts the java threading to only run on a single processor?
ie. make the java app run like it does on a single processor machine?

On Solaris you should be able to do this with Solaris Resource Manager, which is bundled as a part of OS with Solaris 9.

Pages '09 only uses one processor core?

Hello,
some days ago i had to open a document containing nearly 2.000 pages. Don't ask why.
Working with this document was quite complicated because Pages was responding very slowly. I used the activity monitor to see what was going on and i recognized that Pages only uses one core of my eight core MacPro.
I tested iWork on my iMac and MacBook Pro (both DualCores) as well: same problem.
Does iWork only use one processor core?
Kind regards,
roman

How much memory do you have in your system? I'll bet if you check activity monitor (applications/utilities) and go to system memory tab therein you will see lots of page outs. This happens with huge docs and little memory as the doc is being swapped between active operating memory and the hard disk The only way to solve this problem is to get more memory (not storage) in your system. For a 2,000 page doc you're going to need lots and lots and lots of extra gigs of memory. By the way - how big is the too big file of yours?
Number of processor cores isn't going to solve the issue if you have pageouts. It is a system memory/size of document issue and completely unrelated to how many processor cores you are using.

Dual G5 only using one processor in Logic 8

So...
Why does my Dual G5 only use one of the two processors in Logic 8? The one processor will go to max, stop the song from a cpu overload, yet the second processor never kicks in.
Please help! U_U
Thanks,
bp

it seems that the buffer settings on audio preferences are too small.
use this setting:
I/O Buffer Size: 512
Process Buffer Range: Large
Or... you are using some heavy third party Virtual Instrument that don't support Altivec on PPC processors.
(many software houses make good plugins that works fine on Intel processors but they forget to use Altivec implementation for PPC Mac side)

Only using one processor on Mac Pro

I can't figure out how to tell the software to use the other 3 processors. (Only one lights up in the CPU panel out of the 4) I've searched and can't find any answers...
Mac Pro 10.4.10 with Logic Pro 8 & 5 gigs ram. Any help would be much appreciated!

Can I put a dual processor in my power mac g5 which only has one processor right now

Can I put a g5 dual processor into my power mac g5? I have a power mac G5 but it only has one processor so I wanted to upgrade to the G5 dual processor found in the later version power macs. Would I be able to do this? If i could do this would i need another fan or other parts? I was also thinking of putting more ram in and another hard drive. PLEASE HELP

Exactly what to do with ram and video is hard to say without the model details. You can go to http://www.everymac.com and click on Power Mac G5 and then find the machine you have. The detailed info on the machine will show how much and what type of ram you can put in (I always use ram from either OWC, http://www.macsales.com or Crucial, http://www.crucial.com) and also gives the installed video card info. OWC would also be a good source to see what video cards are available that will work with that logic board.

AME is only using one processing core out of six.

I have not been able to figure out why AME is only using one of the six processing cores that I have in my Core i7 hex core processor. I'm running Windows 7 Ultimate 64 bit and the latest version of AME 2014 CC. When I render in Premiere Pro CC 2014 all cores are utilized. The codec that I'm using in AME is "YouTube SD 480P 29.97 - H.264". The video that is being encoded is fairly complex but it is only 30 minutes long and AME is estimating 18 hours to completion. That seems pretty excessive for that length of video.
Any help would be greatly appreciated.

Re: AME CC2014 Very Slow Encoding

Why only using one CPU

Just noticed when importing CD into iTunes on my MacBook is only uses one cpu, with activity monitor it show 98-100% CPU and never goes over 100%
My fans also run when importing, I use lossless.
Why not use more CPU speed?
R

I believe only applications writen to do so will take advantage of dual processors. I guess iTunes has not yet been updated for dual processor use.

Multisim 11 only uses one CPU core during simulation

Hi,
Just recently I've been using MultiSim again, v11 if that matters, and simulating goes slow, to my opinion that is.
Now there are two things that I've noticed:
- Multisim only uses one of two CPU cores during simulation, not both;
- I've enabled CPU throttle (AMD's Cool'n'Quiet) but corespeed remains very low even though Multisim needs CPU power while simulating.
The simulating of a NE555-based LED-flash circuit requires about 28 seconds to get to 100ms in the simulation. Now if I can get the CPU to throttle up, by for example having Prime95 stress one of the two cores, then the simulation only requires 12 seconds to get to 100ms.
So here are my two questions:
1. Is Multisim 11 capable of using more than one CPU core while simulating? If yes, how can I get it to use more than one?
2. Probably not the right forum to ask, but is there a way to force Windows 7 Ultimate x64 to throttle up the CPU when Multisim starts simulating? Since Multisim does not seem to stress the only core it uses enough to throttle it up. Using Prime95 on one core does trigger a throttle up.
With regards,
Bart Grefte
Relevant specs:
Windows 7 Ultimate x64
Multisim v11
AMD A4-3400
16GB RAM

Completely forgot this topic....
Is there a good reason why there is no multicore support? Multisim can certainly use it for simulating.
As for the CPU throttling, I found a batch that can increase/decrease the "minimum processor state"-setting and it works immediately, no reboot required.
@echo off
powercfg.exe -getactivescheme > "%userprofile%\appdata\~apo.tmp"
set /p v_currentscheme= <"%userprofile%\appdata\~apo.tmp"
set v_currentscheme=%v_currentscheme:~24,36%
del "%userprofile%\appdata\~apo.tmp"
powercfg -setacvalueindex %v_currentscheme% 54533251-82be-4824-96c1-47b60b740d00 893dee8e-2bef-41e0-89c6-b55d0929964c %1
powercfg -setdcvalueindex %v_currentscheme% 54533251-82be-4824-96c1-47b60b740d00 893dee8e-2bef-41e0-89c6-b55d0929964c %1
powercfg -s %v_currentscheme%
exit
Usage is simple:
Start -> run -> c:\pathtobatch.bat 100
for "minimum processor state"-setting at 100%
Start -> run -> c:\pathtobatch.bat 5
for "minimum processor state"-setting at 5%
Please note that "set v_currentscheme=%v_currentscheme:~24,36%" is not the same for every language. The original batch had "set v_currentscheme=%v_currentscheme:~19,36%" (most likely for the English version of Windows 7), but since my Windows install is in Dutch, I had to change it in order for it to work.
Running the batch with @echo off removed will show why.

Each iCloud account only has a single iCloud account. If you want, you can add up to 3 alias addresses that will receive email in the same iCloud inbox, as explained here: http://support.apple.com/kb/PH2622.

Can I install CC on three computers - I only use one of them at a time?

I'd like to use CC on three computers in three cities where I travel - I only use one computer at a time - is this possible with a single license? If so, how?

As long as you sign out of at least one of them you can. Sign out before you depart from a given city and you should be set to sign in at another.

Since installing an icon-editing add-on, I can't open tabs any more / I can only use one tab at a time.

Ever since I installed the add-on Favicon Picker 2 that lets you change the bookmark icons, I can't open tabs any more. The second tab will open, but if you try to go to a site, the FIRST tab redirects to that site. Basically, I can only use one tab at a time. Is there any way I can keep this add-on and use tabs?

Oh, wow - look at that, you're right :) I didn't want to uninstall the add-on as I like the feature, but simply by disabling it you can keep the new icons AND use tabs. Thanks dude!
(The add-on is Favicon Picker 2 0.6.2.15 by the way - some of the user reviews report the same problem.)

2 atv's both have home sharing enabled but one asks to turn on home sharing on my pc but it is on so can only use one at a time to watch movies from my computer

2 atv's both have home sharing enabled but one asks to turn on home sharing on my pc, but it is enabled on pc so I can only use one at a time to watch movies from my computer

Both atv,s are on the same network, they are wirless and the computer can see them and they are named different.
what ever one i switch on first gets to stream from my computer and the other one asks for home sharing to be switched on, then if i switch both off and start the other one first it gets to stream and the other one which worked asks for home sharing to be turned on. i have hidden all functionality, netflix etc as these are for my 7yr old kids.

Hello,
see >>> http://helpx.adobe.com/creative-cloud/help/install-apps.html here >>> How many computers can I install on
I quote: You may install software on up to two computers. These two computers can be Windows, Mac OS, or one each.
If you install on a third computer, it will request you to de-activate on the other two computers. You can then reactivate one of the previous two computers, and use Creative Cloud apps on it.
Good luck!
