Message 17706 - Posted: 28 Oct 2013, 21:13:19 UTC

I have upgraded two of my macs (129119 - Mac Pro 3,1 with an ATI Radeon HD 5770 video card and 110905 - iMac 12,1 with an ATI Radeon HD 6770M HD video card) to OS X 10.9 Mavericks. Now all of my C@H OpenCL tasks for these computers run for <30 seconds, then halt with a "Computation Error" message. These units were crunching C@H OpenCL tasks just fine under the latest version of OS X 10.8. By the way, I reinstalled BOINC after updating the OS. Any advice? TIA!

........... Same issue here - have not been able to rectify it on my side by re-setting, reinstalling etc. I guess there is an app or server side issue.

Send a PM to Slicker as he is the one who can fix it for you.

Hi all!

I've a problem too since Maverick!
The task starts and stops 2 s later with that message:

Sam 2 nov 17:01:30 2013 | Collatz Conjecture | Starting task mini_collatz_2382381840356711573864_103079215104_1 using mini_collatz version 410 (opencl_ati) in slot 17

Either for Collatz, Mini or Solo!
If you need more infos, let me know!

Thx to have a look...!

Hi All:

I PMed Slicker and he suggested a response that, alas, has not worked with either of my computers. If I get something to work, I will post to this thread. Sorry that I don't have better news.

Regards,

Dave

By the way, could you provide us with additional details concerning the computer system that is not working? As it turns out, some of my slower computers that are running OS X Mavericks are capable of processing C@H OpenGL work units. Thanks!

Yes! Of course!!

It's a Mac Pro "early 2009", bi-xeon quad core 2,93GHz, 24Go of RAM, GPU Sapphire (AMD) 7950 HD 3 Go RAM and running under Mavericks.

It was running fine under Mountain Lion

It's here : http://boinc.thesonntags.com/collatz/show_host_detail.php?hostid=119397

Thx for searching…

..... Slicker's suggestions didn't work for me either - so currently crunching PrimeGrid on my iMac - would rather be 'doing time' here though!
Will keep an eye on the forum ......

You can find a test version that I __hope__ solves the OS X Maverick issues at:

Has anyone found a fix for this? I have the same "Computation error" issue, on three separate machines, a 2012 mac pro w/2 5770s, a 2011 mbp with a 6750m and a 2011 mbp with a 6770m.

osx 10.9.1

As the same executable works for CPU and nVidia applications, it appears to be a problem with the ATI OpenCL driver. Collatz isn't the only OpenCL application that has problems with the Apple implementation either. Google the error messages and you will see there are a number of others. Yet, AMD and Apple have said and done nothing as far as I know to fix it.

Being a bit of a conspiracy theorist when it comes to businesses stabbing each other in the back, since Apple only uses Intel CPUs and only recently started using AMD video cards, I don't see AMD going to extremes to give Apple a fix.

Apple also doesn't move very fast when it comes to video driver issues. They seem to wait for the next version to fix an issue. Their IT people don't seem to grasp the concept of a patch or bug fix evidently.

It works for some apps though. So why not Collatz? Until the AMD OpenCL compiler returns an actual error that explains why it can't compile the kernel, there's not a lot I can do, especially since I don't own a MAC with an ATI GPU nor do I plan to purchase one. If the one and only OpenCL vendor is Apple on Apple hardware, then I expect an OpenCL kernel that runs on the CPU and also an nVidia GPU to run on the AMD GPU as well. Same driver, right? Or is it? I have a feeling it is an AMD driver and Apple puts their name on it. Kind of like the original "IBM DOS" was really Microsoft. It sure isn't made by nVidia since their GPUs work. That, or Apple really does design their own drivers and their developers haven't figured out the AMD hardware yet since Apple didn't support it for years.

Problem still remains with those two Macs (MacPro 3,1 w/ATI HD 5770 and iMac 12,1 w/ATI HD 6770M), even after upgrading to OS X 10.9.2. So, downgraded the MacPro back to OS X 10.8.5. Whew, boy, what a nightmare. Had to go back to OS X 10.6 then through OS X 10.7 to OS X 10.8. Took ~48 hours, but finally got the machine to crunch C@H GPU tasks. Will take another day or two to reinstall my productivity apps and backup the machine.

I find it ironic that Apple was the one boasting that they supported OpenCL before anyone else when it turns out that their OpenCL implementation has the most problems when it should be the most stable due to its age.

Maybe if everyone with an ATI/AMD GPU complained to AMD and Apple they would fix it.

Message 19415 - Posted: 9 May 2014, 20:23:27 UTC - in response to Message 19058.

Is anyone using a newest generation MacPro (cylindrical model with the AMD FirePro D300 or D500 GPU) to crunch C@H GPU tasks under OS X 10.9? I am contemplating a replacement to my CTO/BTO iMac 12,1 and C@H GPU crunching and OS X 10.9 compatibility are a must.

Another (cheaper) possibility is to replace the ATI HD 5770 GPU in a 2008 MacPro 3,1 running OS X 10.8 with an NVIDIA Quadro 4000 GPU and upgrade the OS to 10.9. Is anyone crunching C@H GPU tasks using a MacPro 3,1 with the Quadro 4000 GPU under OS X 10.9?

TIA for any advice or assistance.

Or, is anyone crunching Collatz GPU tasks using a 2008 MacPro 3,1 and an EVGA GeForce GTX 680 Mac Edition GPU?

I just upgraded my old Mac Pro to the 2013 model with 2xD500s, have just got BOINC set up on it, and noticed that I've been getting some calculation errors. Running OS X 10.9.4. I haven't got the exact work unit details sorry. I'll keep an eye out and and if you can point me where to get additional information the next time it pops up, let me know.

Model Name: Mac Pro
Model Identifier: MacPro6,1
Processor Name: 6-Core Intel Xeon E5
Processor Speed: 3.5 GHz
Chipset Model: AMD FirePro D500 (x2)

The unit that just failed was:
Solo Collatz Conjecture 6.06 (opencl_amd_cpu)

I just tried a WU on my new MacPro6,1 and it error=ed out almost immediately :-(
http://boinc.thesonntags.com/collatz/workunit.php?wuid=7647884

PrimeGrid also has an issue which they possibly/probably solved (my machine runs the new test app fine). Perhaps they could provide some useful info...

I submitted the OpenCL bug to AMD twice now. Still no response. If optimization is turned off, it works fine, but it runs soooo slooooow that you may as well just crunch on a CPU.
