Both your hosts report 4 CPU cores according to Boinc:

Computers belonging to msketers

You'll have to post the log messages for us to understand what you're talking about.

2) Message boards : Cafe Einstein : Suddenly puzzling error message (Message 141156)
Posted 2 days ago by Claggy
You posted this same problem over in Technical News, where I made some detailed comments I won't repeat here.

He posted here first, but might have been redirected..... ;)

I don't monitor the café subforum here, so hadn't noticed he'd already posted here.

3) Message boards : Problems and Bug Reports : BOINC claims no disk space available despite many GB being there (Message 141152)
Posted 3 days ago by Claggy
So how do I fix the problem? As I say, there is plenty of free disk drive available yet the error message says none is available. I have not changed anything since installing the program.

You're set disk_min_free_gb as 50.00GB, you only have 48.91GB free, Set the 'Disk: leave free at least x GB' to a lower value, say 5GB, instead of 50GB, in either the Web Computing Preferences, or locally in Boinc Manager if you're using local computing preferences (these override the web computing preferences).

Posted 3 days ago by Claggy
I am running the latest BOINC client software and both my programs have stopped running - reporting the same error message claiming that no space is available despite many Gb being there. Any advice? Lawrence

Your contact log says you're not allocating enough space, or more to the point reserving too much:

You can try setting <skip_cpu_benchmarks>1</skip_cpu_benchmarks> in a cc_config.xml

http://boinc.berkeley.edu/wiki/Client_configuration

<skip_cpu_benchmarks>0|1</skip_cpu_benchmarks>This will disable the periodic benchmark testing as well as block the 'run CPU benchmarks' from the manager menu.

Posted 29 days ago by Claggy
I have just noticed after getting the AMD drivers updated this in the boinc logs, and clinfo reports the Intel GPU.

26-Apr-2015 19:02:57 [---] OpenCL CPU: Intel(R) Core(TM) i5-4690K CPU @ 3.50GHz (OpenCL driver vendor: Advanced Micro Devices, Inc., driver version 1642.5 (sse2,avx), device version OpenCL 1.2 AMD-APP (1642.5))


So am I right in saying AMD have just released a OpenCL driver for Intel GPU for linux?


No, that says the Cental Processing Unit, ie the CPU has OpenCL support via the AMD drivers, no mention of an Intel GPU there.

Please could somebody outline the steps needed to get and compile the latest version of BOINC so that Raspberry Pi 2's can run neon enabled version.

How about the Building Boinc for Einstein@Home and the Raspberry Pi 2 thread?

10) Message boards : Problems and Bug Reports : BRP4 Intel GPU app feedback thread (Message 139972)
Posted 52 days ago by Claggy
I've installed beignet and it is even detected by boinc!
OpenCL: Intel GPU 0: Intel(R) HD Graphics Haswell M (driver version 0.8.0, device version OpenCL 1.1 beignet 0.8.0, 128MB, 128MB available, 512 GFLOPS peak)

Now how do I get einstein running on this? :)

Urs at Lunatics got Boinc to detect his Intel GPU with beignet 1.1 on openSUSE 13.1:

Mi 01 Apr 2015 06:30:06 CEST | | OpenCL: Intel GPU 0: Intel(R) HD Graphics IvyBridge GT2 (driver version 1.1, device version OpenCL 1.2 beignet 1.1, 2048MB, 2048MB available, 128 GFLOPS peak)


But it wasn't all good news:

No luck with Luxmark and intel_beignet, some basics like clGetDeviceIDs(-1) or clBuildProgramm(-3) fail
