Sort speed up in CPU intensive simulation
I am running a simulation in which I do
sorts embedded in sorts in each trial. This
simulation runs 5 times faster in FORTRAN
on an Ultra 5 than in Java (I use Sun's FORTRAN
compiler with the -fast compiler option and I use whatever SDK is distributed with Solaris 8 with the -O
compiler option). Is the JIT compiler the default
Sun compiler? Is there a real compiler (rather than an interpreter) available for Java on Suns?
JIT technology has been updated to the HotSpot technology. The following is a clip from a FAQ on the tool.
-------------snip---------------------
What's the difference between the -client and -server systems?
These two systems are different binaries. They are essentially two different compilers (JITs) interfacing to the same runtime system. The client system is optimal for applications which need fast startup times or small footprints, the server system is optimial for applications where the performance is most important. In general the client system is better on GUIs. Some of the other differences include the compilation policy used, heap defaults, and inlining policy.
-------------snip---------------------
Class code is run and analyzed for "hot spots" that are high usage, which are compiled to native code; the remainder of the program is interpreted. The mix is controlled by java options -client and -server. The default option is -client.
The FAQ is here:

So I have a Flex app, which can be cpu intensive at times, with some ghosting issues ( see attached image ). I had this issue once before with just IE8 and textfields, but now its happening with everything in the swf and in every browser (Chrome, IE, FF). Even if you let the app sit after loading so the cpu slows down it still happens.
I ran a test when I had the text issue in IE8 (via Alex H.) where I took a bitmap snapshot of the screen from within Flex and it didn't show the ghosting in the bitmap.
I have a feeling this is an issue with the browser refreshing? There is a js call that you can use to force a screen refresh (not the webpage) but that didn't work either. Just wondering if anyone else has run into this issue?
TIA, JasonTerpstar,
I was wondering if you have had a chance to use Motion yet. I have a MBP, and using Zapfino fonts with SciFi Glow crashes my system every time. I would be interested to see if this is the case on other intel based systems. This has led to a failure of my main logic board twice over the last month. See my thread:
http://discussions.apple.com/thread.jspa?threadID=614641&tstart=25
Also, of the two GB ram I have installed, FCP doesn't seem to utilize more than 100MB of RAM. Although the VM size is several GB for the app. I noticed that in order to utilize both cores on my MBP, Airport had to be turned off.
Also, as Ned Snowing was saying, there is no doubt that there are going to be many software bugs that must be sorted out. Especially since this program is being adapted for intel macs, and not re-written. -
Problem with animation and separate CPU intensive thread.
Hi All,
I'm in the process of writing a Java chess game with a computer AI. I've got everything working except for the animation of the computer making its move. Sometimes it works, sometimes it doesnt.
Here's the problem:
After the computer has finished deciding what move to make (CPU intensive - using standard Minimax w/ Alpha Beta pruning), the thread terminates passing the move to the animation thread (implemented using javax.swing.Timer). My delay is set to 50. But the multiple calls to repaint() in the Timer thread all get collapsed into one (they somehow get bunched up) causing a major display glitch!
Sometimes this happens, sometimes it doesnt. I wanted to know if i could write some kind of wait function to wait until the CPU is free to process quick repaint() requests so that my animation can look descent all the time.
Thanks for any help.
jairam at ecf dot utoronto dot caIn the javax.swing.Timer class is a method called
setCoalesque(boolean) (I think I spelled that wrong, but you will find it)
By default the Timer class does exacltly what you mentioned, it merges multiple events into one when the application is too busy. Call setCoalesque(false) to receive all the events from the Timer. -
What is the less CPU intensive method ...
Hi,
With my Apple TV, I can select directly my music library from Apple TV's menu on my television set. I can also choose from iTunes to stream to my Apple TV through AirPlay. Does both method use my computer's CPU the same way ? Is there a method that is less CPU intensive ?
Regards.
Robert LespéranceIn terms of load on your system they are identical.
The only difference is in the first scenario the AppleTV is pulling the content from the Mac (i.e. telling iTunes "give me this track/video/whatever) and in the second scenario the Mac is pushing the content to the AppleTV (i.e "here, AppleTV, display this video/audio/whatever stream").
After the initial negotiation (push vs. pull) the load on the host system is identical - read the file off the disk and transmit it to the AppleTV for playback. -
Looking for Mac that can handle CPU intensive apps (Music & Video)
Hi everyone, I am looking to get a new mac in the near future but wanted to know which Desktop mac is best for music and video? I was thinking of the new iMac but not sure if they are powerful enough? I need something that can handle CPU intensive stuff. I will be using it mainly for video editing and music producing
In a nutshell,
Look at the new 27 inch screen iMac models.
Get the fastest optional CPU,
Decide which optional GPU you'd be comfortable with.
Get the base 8 GBs of RAM and then purchase extra, cheaper RAM through third party Mac RAM sellers.
Then add as much RAM as you think you need. The 27 inch screen models can take up to 32 GBs of RAM.
Decide on optional storage sizes.
If you need a CD / DVD optical drive, these are no longer built-in and you will need to budget for a good external optical drive.
Budget for 3-year extended AppleCare warranty service.
In case of reliability issues with the first 5 years of operational life, the iMac will be covered with free warranty service for the first three years.
Good Luck! -
10.5.7. why so CPU intensive on PBG412"?
I just installed 10.5.7 on my PB G4. The CPU appears to be always maxed out, and as a result
my brand new battery which lasted 4hrs under 10.4.11 suddently dropped to just over 1.5 hrs.
Not to mention the computer is now hotter all the time.
Is there a way to moderate the CPU usage of 10.5.7?

If you just installed Leopard over Tiger, Spotlight will be indexing any and all volumes you have not excluded. This is an energy/CPU intensive process. See if the dot in the center of the spotlight magnifying glass is winkling. If so, it's still indexing.
Run Activity Monitor and look at the top processes.
Or run

in the terminal. -
Which is more CPU intensive?
Which is more CPU intensive, tracking to an audio track and looping that, or using Logic vitual midi instruments? Plug-ins and automation on audio tracks or Logic virtual midi instruments? Third party plug-ins like Waves or Izatope or Logic plug-ins
A bit hard to answer, as you need to be a little more specific, but generally:
tracking to an audio track and looping that, or using Logic vitual midi instruments?
Depends on the instrument - Ultrabeat or Sculture can be pigs, for example, but generally recording audio tracks (lots of them) will tax your hard disk more than CPU.
Plug-ins and automation on audio tracks or Logic virtual midi instruments
Again, which plugins? Some hardly make a noticeable difference, others like Space Designer can get intense. Automation - very little.
Third party plug-ins like Waves or Izatope
Don't use Waves, but Izotope Ozone 3 is a real hog - but worth every bit of it - I love that plugin. -
Debug ip bgp update is cpu-intensive
Hi,
I would like to know if the command in the subject is cpu-intensive or not.
Thank you very much.
Paolodebugs always use cpu to one extent or another.
debug of bgp updates should not be too impacting unless you continually have tons of updates.
it should be ok to run during production hours if you have very few bgp changes/updates occuring. -
What does cpu intensive mean?
I downloaded free trial of adobe audition 3, when trying to remove vocals to make karaoke song a message came up saying cpu intensive
can anyone please tell me what this means, and the vocals where still there.
Thank you
mimsypooThanks for all the info,
I tried remove vocals from various sources without success,so I guess
this programme isn't any good for what i am trying to do or maybe it,s me.
Thank you Mimsypoo

CPU Intensive warnings come up when using effects that are not suited for real-time use. This means it's fine to use the effect on a file where you don't mind waiting a few minutes for it to do its thing, but you wouldn't want to plug the effect into a track and try to remove vocals from a microphone you're singing into. It requires the computer to do too much calculation and it wouldn't be able to keep up.
As for why your vocals were still there, vocal removal is a very complicated procedure, and honestly more often than not, you won't get satisfactory results. When a song is mixed, often the vocal portion is placed in a very specific portion of the stereo field - usually right in the center so that both ears hear it equally. When this is the case, you can usually isolate and remove this portion of the audio if you can determine where in that stereo field it is located. Other songs, however, may spread the vocals out more broadly, process it with several effects that migrate around the stereo field, or even use multiple recordings of the same vocals in different locations. This makes it much more difficult, as close to impossible as can be without fully committing myself, to accurately remove the vocals without affecting a significant portion of the rest of the track.

Dear all,
How do i know if a util/programme is cpu intensive or io intensive.
Regards,
YoonusSounds like the same problem I had with my H55 with original BIOS and RAM compatibility. BIOS updates include memory compatibility so it's recommended you update BIOS for that reason. I had an H57M-ED but it came with BIOS 1.3 and didn't have that problem. That being said I prefer the Crucial RAM you see in my signature for the H55/H57 MB's.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820148262
Wise decision not trying to flash BIOS yet. Do like Jack said before anything else but I would recommend returning RAM and exchange for Crucial. -
Is it possible to speed up CPU intensive tasks....
...using the GPU or another mac computer as a supplement using FireWire 800 as a connection.
My MacBook Pro 2.53 takes ages to encode H.264 1080p files, and I'm not prepared to compromise the quality. Is it possible to connect another MacBook Pro 2.53 (Dad has one) via FireWire 800 and use its cores?I wasn't really referring to controlling the amount of CPU each application might use.
What I meant was : If I have 2 MacBook Pros each with Intel Core 2 Duo 2,53GHz Processors, could I, by linking the computers using FW800, essentially create a virtual Quad Core 2.53GHz, thus reducing my export times in iMovie by a factor of nearly 2 (there will be lag)?
This would mean I wouldn't have to buy Turbo.264 HD, meaning that the quality of the output would be the best it could be.
Any suggestions? -
Memory Speed loss with CPU upgrade 2.6 - 3.0
I have a n 875P Neo board with 2 banks 512m DDR400
I have just upgraded my cpu from 2.6G (800 FSB) to 3.0G (800FSB)
My BIOS is ver 1.8 (8/9/ 2003)
I have found that my memory speed timings have dropped by 30% since the upgrade. Will I get better results if I update my bios to ver 2.0 (the latest bios)??
Sysoft Sandra Memory Benchmark shows to memory timings to be about 25% lower than expected
Can anyone help??
Thanks
M MillerThe 875P Neo and 865PE Neo2 boards are kissing cousins They have a lot in common.
It would help if you create a signature and put all your hardware information in it. Things like what type of video card and what type of ram all have an impact on what performance modes you can operate under. See the Rules at the top for what to include and how to do it.
You should also read P4 Neo Unofficial Guide and Moan Guide. -
Memory Speed Wrong In Cpu-z I have ddr533
Sorry for the double post didnt mean to do that
WELL I finally got my better memory to see how far I can push my prescott but only thing is my memory speed is showing up as pc3200 in cpu-z I am running in dual channel and yes I do have one in each slot (1 and 3). Can any one help on this issuse and what setting do I set it to in the bios auto?any help would be great. and what would be good timings for this memory.UnderTheSun,
I can run 3-4-3-7 with SPD set manually with PAT=normal(Disable) and read the same on CPUZ using Bios 3.6, are you always get 3-4-4-8 wiht SPD setting manually?
I dont have this problem with FSB above 250 mHz (testing with CC I can reach FSB 261 mHz)
On what FSB did you have CAS set to 2.5 on Bios, since even I set it manually on bios with CAS value 2.5 the CPUZ is always read 3 with PAT=normal(disable).
Funny thing with this mobo CAS value always set to 2.5 if I turn PAT=Fast (Fast, Turbo and Ultra Turbo always have the same memory speed using memtest86+) and the bad things is I loose the CAS value 3 in Bios so I need to reflash the bios.
I cannot change the CAS value to 2.5 with this mobo as shown on the following link,
http://www.anandtech.com/memory/showdoc.html?i=1867
I would like to try OCZ PC3700 Rev.2 EL Gold Edition which in my opinion working best with this 'P' series regarding DOT and manual OCing as shown in the following link,
http://www.anandtech.com/memory/showdoc.html?i=1940
According to OCZ office this DDR is discontinued so I need to find it on the online store and hope can get it.
So finally I think we need to wait for the newer bios of the 'P' series.

There are no recommendations to improve the statement.Is the CPU utilization to 100% generated from an Oracle process ?
Is there any utility in Win 2008 or Oracle to check the threads from the Windows side ?
Thank you.Thanks to all.

Kernel_task high cpu usage, high fan speed, and low cpu tempterature
Hi,
I've noticed that a lot of people have been having trouble with the kernel_task process, but I couldn't quite find a situation similar to mine (most seem temperature related).
Here is the situation (15' MBP, mid-2010):
- on boot (while the apple logo is shown), the fans speed suddenly jumps, and stays there, even if the computer has been off for a while.
- boot takes a little over a minute, which is considerably slower than what I was used to before today
- when finally started-up, the activity monitors shows kernel_task using between 160-180% of the CPU!
- temperatures are shown to be around 30C, except for the mem controller at 40C (still very low temp), but the fan speed is arround 6000rpm for both fans.
- this happened out of nowhere, as I woke the mpb from sleep this morning.
Since then I've tried:
- multiple reboots
- install all updates
- uninstall flash player (some people where having trouble with that)
- empty the system cache with Onyx (reported as a cause of slow boot)
- reset PRAM
- reset SMC
- put some ice packs under the mpb to cool things even further!
And so far, nothing has worked! I've had this laptop for 1 year, and nothing had ever failed. I upgraded to lion a few weeks ago, and everything had been working fine since the upgrade. This really happened out of nowhere, and none of the many forums I have read could offer a solution, and cals to apple support do not seem to yield better results (though I scheduled a call with them at 9am this morning, we'll see).
Has anyone had a similar set of problems?
I appreciate any help or advice you may have!
Thanks!
-SebastienI have the same issue (2.66 2010 MBP Hi-Res Anti Glare.)
I took it to Apple Store Covent Garden, JUST within warranty.
18 days later my machine has a new Main Logic borad, heat sensors, top case, palm rest. etc.
I turned it on.
The fans kicked in. All processors at 50%, big ole kernal task.
I took it back, geniuses rest SMC and tested it under load and it was fine.
weirdly it failed diagnostics at first but then seemed fine
I came home. Fans kicked in...
I took it back. Diagnostics failed heat sensors again
Replaced logic board and heats sensors again, but more carefully this time just in case, tested again.
I took it home. FANS FANS FANS.
Last time I was in the store I was told my machine was fine and had been thoroughly tested.
In mac store, no fans.
I erased hard drive and clean installed Lion
FANS
I replaced hard drive with OCZ SSD, clean LION.
Fans
Software update
SMC
PRAM
permissions
Onyx complete clean/maintenace
FANS/CPU
switched back to Snow Leopard SSD
PRAM SMC ONYX etc.
FANS/CPU
replaced RAM, memtest-ed. fine, FANS
gonna try again but up to nearly 2 months of all my spare time trying to shut this thing up so I can sell it.
