BUG: Logic only uses half available power on G5 quad.

My G5 quad only seems to get about 200% of the available 400% CPU use. Is this a problem with Logic? Is there a way to work around this, it's a pretty serious limitation?
Any solutions would be appreciated, thanks.

make sure you (a general quad owner you) do this customer relations thing. also, if you live in europe or UK contact your local consumer protection authority.
but mike is right to keep banging on about it. the LP dev team DO look at these forums even if the mods aren't passing complaints along to them.
2 things concern me here;
- the injustice of the situation, that a fix for the latest machine has come at the expense of or before than the next latest.
- apples policy of silence is absolutely crippling its relations with its customers, who have invested heavily in their hardware and software. since apple more than most companies rely on the loyalty factor something like this stretches it to breaking point.

Windows XP Mode (Virtual PC) only uses half a CPU core/thread.

Not only does windows xp mode not support multiple cores, to me it looks like it only uses half a core/thread.
I noticed this because I just setup windows xp mode (virtual pc) on my computer. I updated it, joined it to our domain and then installed our legacy ERP software. This ERP software was designed and programmed to run on windows 98 or 2000, I can't
remember right now, but its hardware requirements are very low. This software runs very slows in the virtual pc, with the processor being the problem.
Matching the processor spike on the virtual pc using both performance monitor and task manager I compared it to task manager running on the host (my windows 7 machine). The spikes in cpu matched one of the threads on my i7 processor (I use threads
because an i7 has 8 threads but only 4 cores). To my surprise when the CPU reached near 100% on the virtual PC the same spike on the host was only about 50% of the cpu thread.
The host has a i7 950, 3.07GHz processor. So this means that the virtual pc can only use up to 1.5GHz. I have not run into the problem reported in other posts on this forum where the CPU is always at 50% or 100% on the virtual PC because when
their is no activity the CPU drops to 10% or less and stays there.
I will now have to use vmplayer, problem is having enough xp licenses for all users.
Was anyone else aware of this?

You can't use a half a thread. Windows VPC uses one core at 3.07GHz, there's no halving the speed of the CPU.
The only way WVPC would use a lower clock speed is if there is power management throttling the CPU speed down. Do you have a power management setting throttling your CPU? Are you sure the problem is the CPU and not disk or network related?
Task manager on the host is not a very accurate way to determine CPU usage of the VM.
If you have the correct version of Windows 7 (Pro or higher) there are no issues with XP Mode licenses, you get one license included with Windows 7. There's no restriction requiring you to use XP Mode with Windows VPC, it will work under 3rd party
virtualization solutions.

Dual Core Mac only using 30% processor power.

Hi,
I'm running Motion on a Dual-core 2.3GHz G5 Power Mac. My Motion renders are really slow - and bring the whole system to a crawl.
Using Activity Monitor and Menu Meters, I can see that Motion is only using, at most, 50% processor power between the two cores.
The machine has 4GB of RAM so that shouldn't be an issue, and I've run the same Motion files on my old 2.0 Dual G5 at home and the renders use 95% of each processor and are much faster.
Is Motion not dual core aware?
Thanks,
Joe

CPU processing in Motion is not the workhorse. GPU does all the heavy lifting. What graphics card are you using?

IMovie only using 50% CPU power

Hi,
When I export my project in iMovie my CPU usage holds at 50%. I accept this does mean I can do other things but would like the export to go faster.
Is this usual for iMovie to only use 50% CPU (and only about 1gb of RAM (of 8gb)) or do I need to do something?
New to Macs so any help appreciated.

Hi
As I get it - Doesn't iMovie take full use of multiple core processors. Not even Pro
applications does this to 100%
BUT
RAM - iMovie or FinalCut are not that RAM hungry - 1 to 2 GB would be OK
Free Space on Start-up hard disk - VERY IMPORTANT
• 25Gb my minimum for iDVD
• 10Gb my minimum for iMovie
• 5Gb and iMovie runs slow and instable
• <1Gb and iMovie might not run OK at all
Other applications running in paralell - results in bad performances
• Energy Saver
• Do not spinn down hard disks
• Use of USB/USB2 external hard disks = Slow and bad performances especially when getting full
FireWire or internal e-Sata performs best.
• Screen savers - may be (by directing it to an empty folder - I got the feeling of slight increase
in performances)
My list on howto speed up iDVD Slightly - might also applie on iMovie.
*Speed up iDVD*
To speed up iDVD
TO GET IT TO WORK SLIGHTLY FASTER
• Minimum of 25Gb free space on Start-Up hard disk - if less than 5Gb slow and unstable - less than 1Gb might even not start.
• Choise of encoding method will give very different productions speeds. On my d-G5 2GHz
*Professional Quality (movies + menus up to 120 min.)* - BEST
Takes about 2 x times the other ones - but if quality is of essence
(Quality might be as good as or even better for movies under 60 minutes - by using Best Performances BUT not for movies up to 120 minutes)
2 hour movie + menu = about 4 hours to encode at it’s best on my system
*Best Performances (movies + menus less than 60 min.)* - High quality on final DVD
1 hour including menu = about 1 hour to encode
*High Quality* (in iDVD08 or 09) / Best Quality (in iDVD6) *(movies + menus up to 120 min.)* - slightly lower quality than above
2 hours including menu = about 2 hour to encode
• Use an as simple DVD-menu possibly without any animation at all. This reduces processing speed dramatically. I use ”Old Theme - and Brushed Metal” and animation turned off.
• An as fast Mac and as many cores/CPUs possibly. My PowerMac G5 has two CPUs and iDVD uses about 120% = use more than only one CPU/Core. How many it can address I don’t know (anyone ? )
• If possibly - Use two internally e-Sata drives - Drive access takes a great deal of time
else FW-800 or FW-400 or USB2 or network storage (slowest and near to useless)
to work on one (internal, boot, Mac OS, Start-up hard disk - will be BAD - and slow
Normally my d-G5 2GHz takes about 2 x movie material when iDVD and Mac OS on one internal HD and material is on the other internal one.
Now with material on an external USB2-drive and an external Lacie FW-400 as Start-up drive material of about 1.5h will need about 4-6 hours to get encoded and burned to DVD.
Choise and use of hard disks is essential.
• I guess that a Solid State Disks might improve speed
• No other programs running in BackGround eg EnergySaver, Internet, AirPort, Bluetooth etc.
• Don’t let HD spinn down or be turned off (in EnergySave)
• Move hard disks that are not to be used to Trash - To be disconnected/turned off
• Goto Spotlight and set the rest of them under Integrity (not to be scanned)
• Set screensaver to a folder without any photo - then make an active corner (up right for me) and set
pointer to this - turns on screen saver - to show that it has nothing to show
• If Mac with only place for one internal hard disk. Then I would try to use an external FW (Mac OS Extended) one as Start-Up hard disk and store material on the internal one.
eg iMac or ProBook or alike.
from Karsten -
• I assume that resolution and codec of source is another factor ... scaling (e.g. 1280x720 to 720x576 = that is an 'un-even' calculation). or, a difference in speed reg. to h264, dv-stream or aic as input ....

Memory usage seems to be replicating with each sync. My iPhone 5s is now full, although I typically only use half.

When I went to upgrade to iOS8, I was surprised to find that my memory was full. Usually it's only half full. On one of these forums, I found a solution that involved a Terminal command to delete a specific library which returned my memory to the normal usage and I was able to upgrade. Thursday I lost my phone, replaced and when I restored from backup the memory was again full. I have not been able to find the command that rescued me last time. I have found advice to restore and have restored various ways. Each time I restore, the memory usage seems to increase by about 200mg so it seems that something is replicating. It is not only "Other" that increases but also "Audio." Deleting all songs didn't help.
I sync both from iTunes and iCloud so this might be the source of the problem.
Any thoughts?

Thanks for your reply. Any suggestions for ways to fix this? If I've already updated using my phone, am I just screwed?

Why is my memory full when i have only used half of it?

Hi all, i have a 2012 MBA 120GB, i am new to mac books but have had all the other apple products for a long time.
my MBA is constantly telling me "memory full" and other messages like that. i have looked at "about this mac" and it displays i have 60gb of music, photos, apps etc, and the other 60gb is "other", and therer is no memory left.
i have deleted all of my emails in all boxes to see if this is it, and it isnt. i dont have any back ups, for our iphones and itunes at all, and i havent set up time machine either. i am at a total loss as to why this could be.
i have avoided using it latley because i cant put anymore photos or music on to it. the only thing that i have done to it since i have had it is install Mountain lion, and microsoft office for mac.
i have looked around for the answer to this and have come up with nothing, i'm no expert at all with a mac, i have looked at installing daisydisk or something like that, but i dont have enough memory to install it!! so if anyone has a step by step guide as to how to sort this out i would be REALLY grateful!!

anyone?

Picture can not be resized to fit the screen, so i can only see half of my face when use it as wallpaper!! Suckss!!

picture can not be resized to fit the screen, so i can only see half of my face when use it as wallpaper!! How can I change it？？

There's a bug with the wallpaper. One thing that helps a bit, go to the photos app, find your pic, 'send' it to be wallpaper. You have a bit more control although not all the function you're used to.
No idea when or if Apple will fix it.

CPU - Only a half core used of six cores

I have a session with three audio tracks and three instrument tracks, one with Kontact installed with LASS violins. This shouldn't be very stressful for a Mac Pro 2013 6-core with 64GB RAM.
Why does Logic not use all cores and how can I force it to use them?

I don't think it's Apple's problem as this happens in other DAW software like Pro Tools and DP.
I changed the the multiprocessor support in Kontakt to three cores and it now is spreading threads so the cores are all at very low usage.
Still the live track peaks though. But when off the track, processors are VERY low.
I would consider this a bug in Kontakt, and apparently this has been going on for a long time. When selecting a track with Kontakt installed, the processors go to one peaking and another about half, all others go black. Weird.

Power Saver Problems M30-344 (CPU only uses 600MHz)

Hi!
In my m30-344 are changed mainboard and display.
At this time i can't use the full 1.5ghz of the cpu!
In the Power Saver Profile i can choose only the cpu-rate 1-3! I have now de-installed this tool and reinstalled the version by the net. But i can only use 600mhz!
What can i do?
[Edited by: admin on 07-May-05 08:18]

Hi
Just need a little more help on this! I rang up pc world today and they had no idea what i was on about with the micro code. The guy kept saying its because i have no prossessor intensive apps running so it would run at 600mhz, he also said that cpuz is probably reporting the wrong cpu speed.
I know this cannot be the case as in the bios it is set to high which will mean it will run at 1600mhz all the time and not drop to 600mhz. I also ran a game in the background, while raring a 600mb file with 6 ie windows open to no avail just to proove to him that it wasnt goin to 1600! :-)
But he still didnt understand! So i need some light shed on what this micro code buisiness is all about because i have to explain to them exactly what the problem is. I need some info on this by tuesday so i can send it off with the laptop! Any help kindly recieved!
Regards

Hi, I've tried charging continuously for 72 hours. But to no avail. It just stopped working out of the blue! I had only used it for about 1 month!

Hi, I've tried charging continuously for 72 hours. But to no avail. It just stopped working out of the blue. Actually I believe I let the battery die off completely. When I tried charging it again, it never worked.
I had only used it for about 1 month.
I bought this in January at Best Buy, and still have the receipt. I was on long business trip and just got back. I can't get the 90 day customer service. How can I get this returned to Black Berry, they won't allow me to contact them without providing my credit card for incidence based service.
Please help! Thanks.

do any LED color happen when you plug it in?
if only RED, then pug in until red goes out, wait 6 seconds and plug in again.
repeat 3 times and wait to see if 5 green flashes while plugged in
after 5 flahes, leave it plugged in for 90 minutes and it should boot up. if not hold power button down for 20 seconds and try again.
You have 1 year warranty, choose option other when calling in and not phone support. This is confusing I know.

My gen 3 iPod Touch seems to have duplicated all my music since updating to IOS 5 so that it now only holds half as much. What can I do about it? I'm using the same iTunes library with OS 10.6 and all software up to date.

Is the camera damaged? Could be a hardware problem.
Try:
Close the Camera app in the multitasking bar, then try again.

You can't - to be able to redeem and use a US iTunes gift card you will need to be in the US with a US billing address on your account. Whilst you are in the Bahrain you can only use the Bahraini store, and you will need a Bahraini billing address on your account

Can I chat or talk with a human on the phone? I have an Adobe ExportPDF Annual. So, if I cancel today, I still have to pay half of the fee? I only used the service once or twice. I was looking for a phone number to call. But, I seemed to have been in a loop. I kept getting directed to this forum. I would have really appreciated a quick link to a phone number. Much more efficient on my end.
I expected to be canceled in a few short minutes via a phone call. Instead of have been in this endless and frustrating loop to this forum.
Help please.

My Logic 9 Pro is only using a core from my minimac (of 4 cores)

Hi, friends!
I´m using Logic 9 Pro, and i have a problem: It is only using one of the 4 cores of my computer (Mini mac).
Can anybody help me?
Thanks!!

Hi.
i am having the same problem. Working with a 12 cores Mac pro, logic 9.1.8 and vep 5(10 instances with kontakt instruments, 16 in each one). only one of the cores is working, sometimes picking, and i am trying to do the aux process as ErikSimon said in his post, but with no success. is there another alternative to this?
help please!!
Thanks!!

Logic 8 using only one CPU while bouncing

Whenever I bounce a project, Logic 8 uses only one CPU. It also spikes this CPU completely, with the CPU meter going into the red area, which is why I am rather keen on persuading Logic to distribute the load.
Any ideas?
(I've given the support document with tips on how to balance multi-core performance a good read, but it doesn't seem to say anything on this particular subject, and following the advice in the document does nothing to change my CPU load.)

Bouncing is a single core process. Just like rendering is in Final Cut Pro. This won't change until Leopard and Apple's ProApps get better at handling multiple cores.
It's redlining because the processor core is working as fast as it can. Computer processors don't just randomly run slower, they use their resources for the tasks at hand. If it only used 50% of a core, the bounce would take twice as long to process.

BUG: Logic only uses half available power on G5 quad.
