The only Intel GPUs that this project (and other BOINC projects) support are those built into the third or fourth generation Core processors with OpenCL 1.2 capability. Sorry. |

Ðто доÑадно. Haswell и такой облом ((. Что ж, ÑпаÑибо за разъÑÑнение. |

This is probably as good a place to ask as any: after I installed my new GTX 750 Ti in my work desktop, I noticed these two lines in the BOINC startup: 01-May-2014 15:21:52 [---] OpenCL: NVIDIA GPU 0: GeForce GTX 750 Ti (driver version 337.50, device version OpenCL 1.1 CUDA, 2048MB, 1867MB available, 2409 GFLOPS peak) 01-May-2014 15:21:52 [---] OpenCL CPU: Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz (OpenCL driver vendor: Advanced Micro Devices, Inc., driver version 2.0 (sse2,avx), device version OpenCL 1.2 AMD-APP (938.2)) I'd not noticed before that I have an Intel CPU apparently using an AMD driver! Anyway, is it possible to use the Intel GPU as well as the Nvidia, and how? I'm currently using a Lunatics install on a Win7 PC. |

This is probably as good a place to ask as any: after I installed my new GTX 750 Ti in my work desktop, I noticed these two lines in the BOINC startup: It would, in theory, be possible to use an Intel GPU alongside another vendor's GPU. The Lunatics installer doesn't yet include a suitable application, but when the various application developers next supply me with a coherent set of revised/updated/tested applications, I'm certainly intending to include intel_gpu (which I have working well) among the available choices in v0.42 However, you are looking at BOINC's detection of an OpenCL driver for the CPU. That doesn't help anyone at all: we have efficient optimised native CPU apps already (and better to come), and adding an extra abstraction layer won't improve their performance. I don't know of a single developer working on OpenCL for CPU. |

Unfortunately, the i7-2600 CPU (like mine http://setiathome.berkeley.edu/show_host_detail.php?hostid=7022545) has an HD2500 Integrated GPU (iGPU), which does not support OpenCL. The i7-3xxx and i7-4xxx have HD4xxx iGPUs which DO support OpenCL. And yes, those iGPUs can be used with a discrete graphics card also. My i7-4770k http://setiathome.berkeley.edu/show_host_detail.php?hostid=7265951 with four GTX750Ti cards has run using the iGPU but it slows the four graphics cards down too much. Perhaps it is bandwidth limited somewhere, so I stopped using the iGPU. |
