Is this supposed to work? Here is the start of my boinc log:ġ 08:01:07 cc_config.xml not found - using defaultsġ 08:01:07 Starting BOINC client version 7.2.28 for x86_64-apple-darwinġ 08:01:07 log flags: file_xfer, sched_ops, taskġ 08:01:07 Libraries: libcurl/7.26.0 OpenSSL/1.0.1e zlib/1.2.5 c-ares/1.9.1ġ 08:01:07 Data directory: /Library/Application Support/BOINC Dataġ 08:01:07 OpenCL: AMD/ATI GPU 0: ATI Radeon HD 6750M (driver version 1.0, device version OpenCL 1.1, 512MB, 512MB available, 72 GFLOPS peak)ġ 08:01:07 OpenCL CPU: Intel(R) Core(TM) i7-2675QM CPU 2.20GHz (OpenCL driver vendor: Apple, driver version 1.1, device version OpenCL 1.1)ġ 08:01:07 Processor: 8 GenuineIntel Intel(R) Core(TM) i7-2675QM CPU 2.20GHz ġ 08:01:07 Processor features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM PBE SSE3 PCLMULQDQ DTES64 MON DSCPL VMX EST TM2 SSSE3 CX16 TPR PDCM SSE4.1 SSE4.2 xAPIC POPCNT AES PCID XSAVE OSXSAVE TSCTMR AVX1.0ġ 08:01:07 OS: Mac OS X 10.7.4 (Darwin 11.4.2)ġ 08:01:07 Memory: 8.00 GB physical, 143.58 GB virtualġ 08:01:07 Disk: 464.96 GB total, 143.34 GB freeġ 08:01:07 Local time is UTC +1 hoursġ 08:01:07 VirtualBox version: 4.2.8 I think this is caused by the graphics switching not working correctly. Error in OpenCL context: : OpenCL Error : clCreateCommandQueue failed: Device failed to create queue: -30 Error in OpenCL context: : OpenCL Error : clCreateCommandQueue failed: Device failed to create queue (gld returned: 10015). As you can see from the error logs, all tasks seems to end with: I woke up, it was still running, then I went away from the computer, the GPU started again and then I got a kernel panic and had to restart. Mostly this happens immediately but I had one task run last night: Unfortunately I get only "Error while computing", as you can see here: Last time I tried the discrete GPU was active even while boinc was suspendend, draining battery. Just updated to boinc 7.2.28 and decided to give the GPU another go. So atleast, now I can use its internal card completely and its not a $3500/- paperweight.Īlso we do not need gfxcardstatus app once we disable the external card.Hi, this might be boinc related, feel free to pass it on. I had previously noticed the Webex Application infact was switching to external gpu and thus causing the system to hung or now reboot in Yosemite.īut now atleast its not anymore doing this, once I have disabled the 2nd GPU. It was coming back everytime.īut the disadvantage was everytime it was switching gpu during normal use it was crashing the laptop and rebooting. So no more recovery mode boot or single user or pram resets or SMC. Now when the system panics- Apple has made some changes in 6770m gpu drivers that is forcing the CPU to reinitialize or reboot the GPU - so now when system reboots it comes back safely. I have noticed in Energy Saver "Automatic switching check box was removed now".Also My external video 6770m card is completely disabled as to test I have tried the game which previously was always going to 2nd gpu but now only using integrated GPU.Īlso before doing all this I have updated to Yosemite. Thank you all I have used the linked procedure - Īlthough while rebuilding the drivers cache it has given me down the line "segmentation fault" but when it booted:
