BOINC application installed on Acer Aspire, model E5-522G-62QT (NX.MWLER.004). BOINC application correctly detects and uses both GPUs - CPU internal and external. | OpenCL: AMD/ATI GPU 0: Mullins (driver version 1800.8 (VM), device version OpenCL 2.0 AMD-APP (1800.8), 1648MB, 1648MB available, 128 GFLOPS peak) | OpenCL: AMD/ATI GPU 1: Hainan (driver version 1800.8 (VM), device version OpenCL 1.2 AMD-APP (1800.8), 2048MB, 2048MB available, 320 GFLOPS peak) However, in configuration on the site I can see two internal GPUs. [2] AMD Mullins (1648MB) OpenCL: 2.0 (see it here -- http://setiathome.berkeley.edu/show_host_detail.php?hostid=8015962) Fix it, plz. CX |

The site will always display a "mismatched" pair of GPUs as a pair of what BOINC believes to be the more capable GPU - it is a "design feature" and has something to do (or at least had something to do) with the scheduling of tasks and the guesstimation of flops....

I think this is only cosmetic - to simplify the web pages only the "best" GPU is shown. In your case the "best" GPU is determined because of "OpenCL 2.0" BOINC reports all the details to the server, I recently made 2 posts about that: http://setiathome.berkeley.edu/forum_thread.php?id=79591&postid=1789475#1789475 http://setiathome.berkeley.edu/forum_thread.php?id=79738&postid=1793876#1793876 Applications know where they run and detect both GPUs OK: Running on device number: 0 http://setiathome.berkeley.edu/result.php?resultid=4970229273 Low-performance GPU detected, default period_iterations_num set to 500 Used GPU device parameters are: Number of compute units: 2 Single buffer allocation size: 128MB Total device global memory: 1648MB max WG size: 256 local mem type: Real LotOfMem path: yes LowPerformanceGPU path: yes period_iterations_num=500 Running on device number: 1 http://setiathome.berkeley.edu/result.php?resultid=4970875081 Used GPU device parameters are: Number of compute units: 5 Single buffer allocation size: 128MB Total device global memory: 2048MB max WG size: 256 local mem type: Real LotOfMem path: no LowPerformanceGPU path: no period_iterations_num=50 Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |
