LR 4 and Multiple CPUs

I am planning to purchase a new computer but before I do I wanted to pose a question to the community at large. First and foremost, I have read up on all the techniques used to increase the performance of LR. I am considering purchasing a Dual 4 Core Xeon or Dual 6 Core Xeon with 16GB of memory and perhaps 3-4 internal 7200 RPM disks, at least one of them to be dedicated to cache. My question is the following: Will LR take advantage of mutiple processors or is this just overkill on my part??

With "create a new folder" you mean that you want to import from a previously not used folder, which is not yet part of your folders-panel list?
I had a similar problem on my Win7-64bit OS, LR 4.1 still, too, some days ago.
I imported from such a new source-folder, but it still did not show up in my folders-panel-list for quite a while. Despite the "previous import" showing the image, and the "show in explorer"-command working.
No real solution did I find, but eventually, after several redundant imports (of duplicate then) brought the folder into the panel list.
No, LR cannot get *full*.

Static data and multiple CPUs

Hi, could anyone explain how data in static data (like static classes, static members of a class etc.) are handled across multiple CPUs in a multi-threaded application?
Thanks,
Lei

nope
its got way too much to do with the JVM and OS
thread scheduling and optimisation (particularly in multiple CPU is a nightmare)
it would also (if the optimisation went that far) depend on the architecture of the CPU in question..
Althon MP each have processor cache (no surprise i guess) but the clever bit is that there is a very high speed buss to share the cache
so in that case (i would guess) that one CPU could handle the static methods for a particular class, or it might be that either CPU could excecute code held in the cache of the other chip
i really dont think that there would be set rules for how java deals with such low level optimisation

JVM's suport for multicore processors and multiple processor systems

Hi all,
Do you have any concrete information about Sun Hot JVM 1.5's support for multi-core processors and also its support for multi processor systems. I ask this because i am looking at deploying a multi threaded application written in Java 5 and want to know the best CPU arrangement for optimal performance.
Does JVM run itself on multiple CPUs?
Does JVM run native threads on multiple CPUs ? at the same time.
Is there a place where i can find out the exact behavior of the JVM in sus environments ?
Thanks.

Hi,
Sun's JVM runs very well on multi-thread/core/chip systems and provides several mechanisms to scale well in such environments (for example Thread Local Allocation Buffers (TLABs), parallel gargabe collection threads etc.). Java threads are 1:1 mapped to operating system threads. There are lots of options that allow you to configure the JVM wrt number of gc threads and so on, although the defaults should in most cases work well. There is a lot information available at http://java.sun.com/docs/performance/index.html and some (quite outdated) information about threading at http://java.sun.com/docs/hotspot/threads/threads.html.

One Java-Process over multiple CPUs on Solaris 8

Hello,
sorry if this question is trivial. I have a java server software (BEA Weblogic) and use it on a multiple CPU machine (e.g. 4 CPUs) with Solaris 8. This Server runs as one system process and creates some threads. Are these threads spread over multiple CPUs or do they stick on the same CPU as their parent process.
So the question is: Am I using the full power of my machine with the 4 CPUs when I'm only starting one of these software servers or do I have to start multiple instances for to use all the CPU power.
I'm using JDK 1.3.1_07 an can make use of the alternate threading library "/usr/lib/lwp" on the solaris 8. This will activate the one-to-one threading for the JVM.
Thanks and kind regards
Falko

Sound like you figured it out ;-)
Keep in mind that you'll probably get better performance, depending on your application, by tuning the heap and the garbage collector. We run on four processor machines, but I could make good use of all four processors until I adjusted the heap size, old/new heap rations, turn on the concurrent gc, and increased the RMI GC interval.
Good luck,
Michael

Thread (won't run on multiple CPUs)

I have read articles that claim java's threads will only run on one CPU no matter how many CPUs your system has. But most of those articles were of old versions of java, but I have mostly dual and some quad CPU machines running Linux and I tested out the latest version of the jdk (1.5) and have soem disappointing results. When I look at the CPU usage while I run multithreaded apps it seems there is always one that is over worked, and I think the other CPUs are just doing OS stuff not java stuff. I then did some tests looking at run times which should be almost linear as I increase my thread count (as long as I keep it under the number of CPUs), so on my quad CPU machines I should 2 threads better than one and 3 threads better than 2 and 4 threads should be my peek performance. The machines I tested were completly idle, and I had the exact same run times for all the runs even a little worse as the numbe of threads was increased. So it looks at though the threads aren't utilizing the multiple CPUs. I then made my program run in seperate threads and there was a linear increase, so there is definatly something wrong with the jdk and threading (on SMP machines) as far as I can tell... Anyone else have input?

New 13" Macbook Pro trying to connect to a Panasonic VIERA TC-L42U30 as second monitor. I've used multiple hdmi-thunderbolt/mini displayport adapters and multiple hdmi cables and still no success. The Macbook does not sense the second monitor (TV). Help?!

I've been a Mac since 2008, so I know my way around the system pretty well. This issue, however, has me stumped. I had an iMac until now and only now am I experiencing some difficulty with my new MacBook Pro. The model I have is the newest 13" Macbook Pro model and I'm trying to connect a Panasonic VIERA TC-L42U30 42" HDTV as a second monitor via the Thunderbolt port.
It worked the first two times and hasn't worked since, after 10-15 attempts with different configurations, turning things on n off, restarting the mac, unplugging the cables, adapters, TV, resetting the P RAM, etc... I've used multiple hdmi-thunderbolt/mini displayport adapters and multiple hdmi cables and still no success. No matter what I do, the Macbook does not sense the TV as a second monitor anymore.
I took the MacBook Pro to the Apple Store, and their "genius" there had it working fine with a DVI connection to a regular monitor. The Panasonic TV I have has HDMI connections and one VGA connection which does not support HD, but no DVI option. I want an HD connection to mirror or extend my MacBook Pro screen. At the Apple Store, they didn't have a Thunderbolt/Mini DisplayPort to HDMI adapter, so he could not try that out for me.
Anyone else have this configuration or another similar one with a Panasonic HDTV?
Ideas? Suggestions? Anything?! Help!!
P.S. I'm running Mountain Lion, if that wasn't already obvious. Everything is up to date in my App Store as well.
Thanks!

Hi There,
I have had the exact same issue but with a projector.
The issue lies with Mountian Lion 10.8.2.
I tried many a combination with no luck to get HDMI working.
Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
Bought my macbook home and voila, now displaying through my projector.
There is a small graphics update after 10.8.1 which seems to be the cause.
Hope this helps.
Thanks.

Hello, I have iMac from Oct, 2010 and have OS 10.6.7 and multiple users. Mail icon was accidently removed along with program. Mail 4.4 is on other users but when I reloaded software my user got Mail 4.3. Mail 4.3 did not work with latest OS. Ideas?Matt

Hello, I have iMac Itel i3, from Oct, 2010 and have OS 10.6.7 and multiple users.
About 3-4 days ago the Mail icon in dock had question mark and was accidently removed, along with program on my user. Oops.
1. Mail 4.4 is on other users and works fine, but for me it does not work and tells me V4.3 does not work with latest OS X.
2. I reloaded software from my user with original disks (Oct, 2010) and got Mail 4.3 again. Mail 4.3 did not work with latest OS. I am unable to load Mail. Gives Yellow error message.
" You have Mail version 4.3 (1081/1084). It can’t be used on Mac OS X Version 10.6.7 (Build 10J869). For more information, click the Help button."
3. Tried to update software and look for update for mail 4.3 on Apple site to no success.
Hate to go to MS-Entorage ( I may need to learn something new and alien) mail program since contracts are in Mail/Address Book.
Ideas?

Matt,
I would download and run the 10.6.7 combo update.

Can I use one itunes account for multiple users and multiple devices

Can I use one itunes account for multiple users and multiple devices?

The iTunes EULA, as I understand it (I'm not an attorney )for Apps is basically that one person can use an App multiple devices, or multiple people can use an App one device..so one to many or many to one, but not many to many....

How to bundle a .FLA and multiple .SWF files in one .EXE?

Hi,
I have a .FLA file which uses loadMovieNum() to load various
.SWF files when each one is called by the user clicking on a
button. Each .SWF file also uses loadMovieNum() to call a second
.SWF file. When I publish the .FLA file as a .SWF file it all works
beautifully.
Now I need to package the entire project into a Windows
projector .EXE file for offline use on a computer without the Flash
Player. When I publish the main .FLA file as a .EXE file, the .SWF
files still load, although they blink before fully loading and
displaying steadily.
What I would really like to do is to bundle all the .SWF
files into the .EXE file so when I send the finished project to the
end user, they only have to deal with one file, rather than a
folder with the .EXE file and multiple .SWF files.
Is there a way to do this?
I am using Flash 8 Professional.
Thanks,
Cam

Since this isn't going to be web-based, why not include all
the external swf files into the same Flash file and then use
attachMovie?
This will allow you to create one .exe file that would
contain EVERYTHING. Since you aren't worried about loading speeds,
you don't have to load the movie clips, but can simply create one
large Flash file.

One premium account and multiple Skype HD devices

Will one Premium account and multiple non premium HD accounts work for video calling? Basically the idea is 10 HD skype devices, the set top boxes connected to tvs will dial into one Premium Mac or PC account for multiple video conferencing.

Yes, one user needs to have a Group Video Calling subscription.
Unfortunately, not all devices support Group Video calling (TV's for example, do not).
Please see our website for more information: http://www.skype.com/en/features/group-video-chat/.

HT4137 iCloud setup with one Apple ID and multiple devices

iCloud setup with one Apple ID and multiple devices

What, exactly, are you trying to do? You can use the same iCloud account on as many devices as you want, as long as you don't turn on iTunes Match. Once you turn on Match, you're limited to 10 devices total.
Is this what you want to do...same iCloud account, but different iTunes/App store accounts on each device? If so, you can do that also.

I have two macs at my house, and multiple iPhones. I want to keep the same apple id as everyone else, but i want to put my own music only on my iPhone. I want to do this with my laptop which is not the family's main iTune's computer.

If you use the same Apple ID for iCloud on each device, yes. However, you can use the same Apple ID for iTunes content on each device, but different Apple ID's for iCloud, iMessage, FaceTime, etc., on each device. That way, you can have whatever iTunes content you want on each phone, but keep all of the other data separate. You can create another Apple ID here:

Totally confused with iCloud and multiple devices

Ok, So we have two each of the iPods, iPads and now iPhones. Do we all share the same iCloud? Can we share apps through the cloud? How do I switch my iPad to the new one I got to give this one to my son. I am so new to all this apple stuff. Only been a few months and I'm still really confused. What all goes to the iCloud? How do we see what's in the iCloud? I really the the idiots instructions I think to figure this all out? Can anyone help me? How can I print from the iPad? Everything I see says iOS 10 something? I believe I only have 6 something?

Do we all share the same iCloud?
icloud is designed so that only one user uses it to keep his/her devices in sync. When multiple users use the same icloud account, they will then be sharing the same email address, contacts, calendars, notes, etc. Usually that is not what two people want to do.
Can we share apps through the cloud?
You buy apps from the itunes store, that's different than icloud, and multiple users can use the same itunes account so that they can share apps, music, etc. For a family, everyone usually uses the same Apple ID for an itunes account and individual Apple IDs for their icloud accounts.
How do I switch my iPad to the new one I got to give this one to my son.
What do you mean by "switch.. ipad to the new one"?
What all goes to the iCloud?
Backups of iOS devices, Apple services that you turn on to share data (settings>icloud; on an iOS device), third party apps that use icloud to sync their data between devices, email, photo stream, and more.
How do we see what's in the iCloud?
Icloud is designed primarily for syncing data between the devices of the user - like getting all computers and devices to have the same contacts or calendars. When you set up syncing (settings>icloud, turn on the services you want synced between your devices), some of that data will also be available to a computer's browser when you log into icloud.com. Otherwise you view the data using the associated app, like the Calendar app to see events. Other things that may be on icloud, like backups cannot be seen. Also iCloud does not provide a photo gallary that others can view in a browser.
How can I print from the iPad?
For that you need an "airprint" compatible printer. See,
http://support.apple.com/kb/ht4356
You can also print to a printer that's connected to a computer, but that computer needs special software, like Printopia for macs.
Everything I see says iOS 10 something? I believe I only have 6 something?
There is no "10", version 6 is the current one. You are probably thinking of OSX, whose versions are 10.x.y. That's for macs, not iOS devices.
