Fiery Posted November 9, 2011 Share Posted November 9, 2011 We've just made the new GPU stress testing feature public in the following AIDA64 beta release: http://www.aida64.co...14gcn7wyrhdzzip It can be used to put stress on one or more GPUs in the system, by utilizing the GPGPU computation capabilities of OpenCL API. A couple of things to note about this new feature: 1) First of all, it is in a beta stage right now. We'd like to hear your feedbacks about it, and collect any improvement ideas. We will only roll out this new feature in an AIDA64 stable release in the first half of 2012. This feature will be disabled in any upcoming new stable releases of AIDA64 that will be rolled out in 2011. 2) Even this first public beta is capable of putting computation threads on multiple GPUs; supports CrossFireX, SLI and AMD DualGraphics configurations; supports mixed GPU configurations (one ore more nVIDIA GPUs + one or more AMD GPUs) under Windows 7; and of course it supports AMD APUs (Llano, Brazos, Trinity) as well. Putting stress simultaneously on an APU and one ore more discrete GPUs is also supported. OpenCL-capable IGP chips and mobile GPUs are supported. Multi-GPU video cards (e.g. GeForce GTX 590 and Radeon HD 6990) are supported. 3) Any OpenCL devices can be stressed, but right now it's not possible to select which devices to stress. Hence all GPU-type OpenCL devices that can be found in the system will be stressed simultaneously. 4) CPU-type OpenCL devices are not supported. We don't plan to support them, since for CPU stressing we have our own solution, the usual 64-bit System Stability Test module. 5) You can check the list of available OpenCL-capable devices on the Display / GPGPU page in AIDA64. All GPU-type devices listed there will be stressed by the AIDA64 System Stability Test. 6) Due to the way GPGPU implementations work, stressing the GPU also puts stress on other system components, e.g. system memory, CPU caches, CPU cores, and PCI Express links. Hence it's normal to have considerable CPU utilization while running the GPU stress test, even when CPU and FPU tasks are not enabled on the System Stability Test interface. 7) Due to OpenCL not being capable of providing a device utilization measurement, AIDA64 System Stability Test is not able to show the GPU load% while the stress test is running. It is however possible to check the GPU load in other places in AIDA64, e.g. on the Display / GPU page, or on the OSD Panel or SensorPanel. 8) We currently have no plans about supporting other GPGPU layers (e.g. CUDA, Stream, Direct3D CS) for GPU stressing purposes. 9) The current GPU stress module doesn't implement error-checking or results validation, hence any computation issues or glitches will not be detected or reported. 10) On old nVIDIA MCP chips (e.g. MCP73) the current GPU stress test may not work properly. We suspect it is due to a ForceWare driver bug or improper OpenCL support in ForceWare drivers. We'll investigate this issue later this year. Please let us know what do you think about this new feature, and what improvements would you like to see about it. Thanks, Fiery 1 Quote Link to comment Share on other sites More sharing options...
