Mac Pro :: Using OpenCL - On Researcher/developer View
Jun 8, 2009
1) from wwdc latest information, Mac pro user will have only 3 Apple official option OpenCL that is : GeForce 8800 GT, GeForce GT 120 and Radeon 4870
2) but I think GTX285 and FX4800 will support too. (At least final ver. of Snow leopard)
3) Assume you want many core the best selection from 1) & 2) is ATI Radeon 4870 because it has 800 stream processor. GTX 285 have 240
4) Assume you want memory speed the best selection from 1) & 2) is ATI Radeon 4870 again because it GDDR5 (but i can't confidentally confirm it when 4870 have lower memory speed and lower memory bandwidth)

I have been reading that Apple worked with nvidia on OpenCL and that leaves me wondering: will ATI see all the same GPU acceleration of nVidia?
I am looking to buy an iMac in the next few months, and am stuck deciding between the lesser nVidia 130 that can use open CL or the fast ATi that may not...

this year I decided to go for a Mac, and almost decided where to start: Im considering to get the Air. But first I must be sure that it will fit my needs. I work as a web developer, for years I have been working with PHP, ASP and the .NET framework. but recently Im starting to get used to Rails, and I heard that Mac is the perfect platform for it. So, I want to know if there are other developers that use the Air too, And what the tools you are using.
Im not the kind of road warrior, but it would be nice if I can reduce the actual 6.6 pounds of my 15" compaq laptop (my spine will thank)
For me the MB Pro is still too big and heavy, and the Macbook have a poor display compared to the Air. So i think the Air is perfect for me. What you guys think about it?

How can I get it ? It ask me for a password, but.. you know what!
Every time I launch XCode 3.2 on SL and go to Documentation tab at Preferences, it ask me for a password.
I want to use it for Java, but when I try to create a new Project it does not appear there.

I checked apple's website and went down to the requirements page. turns out, you require a nvidia or a very very recent ati chip to run openCL. the imac that i own has a ati radeon 2600 pro. what i don't get it, how is a nvidia 9400m more powerful than 2600 from ATI there seems to be no other reason than the fact that apple is being lazy about supporting fairly recent hardware. I only got this imac a couple of years a go and its still pretty new. Does apple expect me to get a new mac?

The broad industry support Apple is building around OpenCL will help increase the critical mass behind OpenGL, the 2D and 3D graphics language Apple uses extensively in Mac OS X. Since the mid 90s, Microsoft has worked to prevent the adoption of OpenGL as an interoperable industry standard in favor of its own proprietary DirectX portfolio of graphics software and gaming tools.

Don't get me wrong, the (apple-shipped) 8800GT has never given me a moment's worth of problem but it would seem that if there is OpenCL support for the GTX285 in SL next month, it may be worth it to drop the coin and get this card (I'll take it as a business expense).
Has anyone heard or seen something about officially supporting this card? When I looked on Apple's website under SL tech specs, this card isn't listed.

I have a question about how OpenCL works. What programs can utilize the GPU for processing? Does it happen automatically, or does the programming within the application have to state that the GPU can be used? It seems like everyone is excited about OpenCL and GPU acceleration, but how often is it used?

I just installed the Java update this morning and when I opened up my Macintosh HD later on in the afternoon I only had 5 folders when there used to be 6. When I went through time machine to figure out what the missing folder is it ended up being the Developer folder. I never use that folder, but I would still like to have all my folders intact.
Does anyone know if the Java update caused the Developer folder to go missing? If that folder is missing who knows what other app's or folders I have missing. I was able to restore of course from time machine, but I'm just curious on why it went missing in the first place. Does anyone have any clues/ideas?

09 Quad Mac Pro, with flashed 1g XFX 4870 ...
all the OpenCL sample apps from Apple, except for the "hello world" example, are failing.
Can anyone else confirm the same errors on their setup? Just so that I know for sure it is due to the 4870.
I will try putting in my GT120 and see what happens.

I've been trying to find a download of the Developement Tools for Jaguar on the Apple site and have failed.I know that it was released as a CD version with the installation CD set for Jaguar. I know that it was also available from Apple as a download. I also know that starting with Panther it was renamed Xcode. However the Developers download site does not seem to have any software covering the years 1998 to 2006. Does the download I want still exist on Apple's site - but I have not stumbled on the right place to go ?

When Snow Leopard came out last year, Apple made marketing out of the fact of having no new features. Arstechnica wrote a splendid review praising the potential of the two new core technologies it brought, and the perspective performance improvements coming from them.
The "radically new development paradigm" was promising for a slower deployment, but I though it would have been compensated by the advantages in speed and code maintainability.
So I've been periodically sampling the Internet for news on either technology. I expected lists of applications employing them, or some visibility on existing apps directories (like "GCD" or "OCL" tags). In lack of these I then resorted to expecting some random block posts from developers, but even of this I find very little.
The most material you find from Robert Watson, concerning applications at the FreeBSD project!
So what happened to these technologies under the Mac? Did they pass ignored by Mac Developers? If so, why? If not, why do they not reflect publicly the same excitement that the competent Ars masters showed?

Despite the unbridled enthusiasm among bloggers for Google's newly announced free WebM codec, a digital video expert has reviewed the new VP8 specification and delivered a severely deflating technical analysis, noting that it decodes video slowly, is buggy, and copies H.264 closely enough to all but guarantee patent issues. What could possibly go wrong?The knee jerk reaction to Google's announcement was to ask whether Microsoft and Apple would immediately jump to support the new codec, given that the two companies offer the default choice in web browsers to nearly all desktop users, and given Apple's strong influence over mobile devices.

In the tech specs for Mac OS X 10.6 Snow Leopard it only lists the ATI Radeon 4850 and 4870 for supported graphics cards for OpenCL so does this new 4670 support OpenCL? I think it would be pretty silly to have the cheaper iMac with the GeForce 9400M support it but not the next step up with a dedicated card.

I want to download apple developer tools XCode on my iMac, but it says I need a later version of OSX. What are the downsides to installing the later version (Lion?). I currently have OS X version 10.6.8 on my iMac and it says I'm required to install version 10.7.3 or later. By the way, is the updated version provided free or do I have to buy it? I'm looking to do all of this so I can start to develop an App for my iPad..

Earlier tonight I opened iCal, only to find that none of my calendars were there. it was completely empty. However, when I changed the view from "Week" to "Month" all of my events were listed (in the proper color) on the appropriate day, but I still had no list of calendars on the left. Subsequent changes between "Day" "Week" and "Month" view continued to display the events properly, but nothing showed up in the calendar menu on the left.
I repaired permissions same thing happened.I trashed com.apple.ical pref (forgot the exact filename)�same behavior. I use .mac to sync between computers, and I use Missing Sync to sync to a Palm T|X.

I have an older MBP (2.2Ghz, 2GB RAM, 120GB HD) and am having problems with PDF files. Well, I guess it would be better described as annoyances with PDF files. I use Adobe Reader and the lag when scrolling is unbearable. Does anyone know of a way to fix this? Can anyone suggest alternate programs that may remedy my problem.
