I've currently got the CPU app disabled and the GPU app enabled. I'm still getting CPU tasks.

Let's do some crystallography again...

It's just a jump to the left...

Was just checking in here and just wanted to suggest before you launch you might as well and go ahead and update the BOINC server.

David Anderson has also made the anti-spam tools more robust which on its own is a great reason to update the server

Well that was fun! I fell agonizingly short of a few targets but no worries because I'll grab those when the project returns.

Good luck in the maintenance and you know we'll all be ready for your return.

Update: Server upgrade was successful. The number of new WUs generated per hour is increased tenfold. However, the parameters of size_regulator are to be optimized...

Just ran out of work on my fastest machine. Perhaps you need to increase by a hundredfold?

What about GT 430 (CC ??)

I will update the OpenCL apps today. I'll let you know when it's done.

It's done.

100% success rate so far (147/147)
Thank you - especially because so few projects take the time to develop apps for OS X and even fewer have a GPU app that works. So as long as you generate tasks, I'll be gobbling them up for my GPU.

Sadly no go. For some reason it couldn't find an OpenCL device, which is most odd.

Here's the stdout1 file:

Parsing calculation parameters...
Calculation-->source is set to Xray.
Calculation-->scenario is set to Debye.
Calculation-->PrintAtoms is set to No.
Calculation-->PolarFactor is set to No.
q-->N is set to 1024.
Calculation-->wavelength is set to default.
Calculation-->PartialIntensity is set to No.

Parsing Block 0...
Block-->centered is set to No.
Block-->centeredAtoms is set to No.
Block-->mol_rotation is set to No.
Block-->mol_Uiso is set to 0.
Atoms-->filename is set to default value.
Atom-->occ is set to 1.0.
Atom-->Uiso is set to 0.
Atom-->occ is set to 1.0.
Atom-->Uiso is set to 0.

All blocks have been parsed.

The following OpenCL platforms are found:
Platform 0: Apple
Platform contains the following OpenCL devices:
Device 0:
GPU: ATI Radeon HD 6750M
Number of compute units: 6
GPU clock rate: 150 MHz
Theoretical peak performance: 0 GFLOPs

Error: No OpenCL devices found.

stdout2 was identical

In case you're wondering, here's the appropriate entry in the BOINCmgr log for this host:

Fri Nov 18 06:21:37 2016 | | OpenCL: AMD/ATI GPU 0: ATI Radeon HD 6750M (driver version 1.2 (Nov 18 2015 20:53:06), device version OpenCL 1.2, 1024MB, 1024MB available, 72 GFLOPS peak)
Fri Nov 18 06:21:37 2016 | | OpenCL CPU: Intel(R) Core(TM) i7-2720QM CPU @ 2.20GHz (OpenCL driver vendor: Apple, driver version 1.1, device version OpenCL 1.2)

Happy to try anything to get it to work.

The new statically linked version of mt_mac is provided already, however, I didn't test it on Mac that does not have macports installed, so I am not sure that the problem is solved. Can you try it?

I believe you can import a selection of teams - at least I think I've seen that on other new projects recently.

If so, it would be great if you can.

All fails for mt_mac (OpenMP-multithreaded for Mac) are for the same host. All fails for opencl_ati_102_mac are also for the same host. Maybe, there are problems with these app versions but better statistics is needed.

Yeah, that's mine.

FWIW this host runs Primegrid, SETI and Einstein on CPU and GPU without any issues.

After my experience with the ATI on Win 7, I tried suspending CPU operation but it made no difference to the GPU results.

I'm always in need of GPU apps for my MacBook so I really appreciate you supporting this platform.

Posted 17 Nov 2016 by Steve Hawker*
i found that you need to reserve one whole CPU core otherwise it can take an age.

Tasks on my 7950 were taking 5 mins or so compared to less than 10 seconds on similar GPUs. Once i made sure it had a full core, times dropped to a few seconds.
