Some of the same chips were used for cards in the HD 70 series, and even into the R5 200 series cards, and do not support DP. All the rest do not in the lower end of the series. The cards could not be grouped by series.įor example, just the HD 5800 and HD 6900 series cards support DP. The way AMD reused chips through the different series of cards meant that the scheme shown in that old post no longer worked. For right now though the effort has been on getting the GPUs in the AMD lines without Double Precision (FP64) support identified and removed from the supported list. It takes having the assignments set up properly on the servers when the projects are configured.Ī similar revamping is being worked on for the AMD cards, that may go into full effect once accepted by the researchers. This has gone the farthest on the nVidia cards, larger systems being assigned to the cards with the most shaders and performance by preference. So the lower end Kepler cards show up as species 3, the higher end ones are species 4 mostly. One change has been to group a bit by relative performance. The post is old, and a number of the items have shifted in use and what they will be used for on the servers for assignments. Pci_device - The PCI device ID as four lowercase hexadecimal digits.ĥ - HD 7000-8000, FireStream 9000, Rx 2xxĤ - Maxwell (Not released, not supported yet)Ī full example: 0x10de:0x0e22:2:2:GF104 Pci_vendor - The PCI vendor ID as four lowercase hexadecimal digits. GPUs.txt consists of lines in the following format:Ġxpci_vendor:0xpci_device:gpu_type:gpu_species:description Whoever actually answers your main question may well clarify this recent change as well … I think that in the GPUs.txt "Greylist" devices with ::: before the end description are Blacklistedįound the following in another post - quite old so may not be wholly accurate (think Species may have more recent entries) but I think at least explains the basic format: I'll let some answer the "how are decisions made" part, but a quick heads up, Open CL 1.2 support is not a "100%" requirement … Until recently it was believed it was, but in the last few days there have been some clarifications and a number of GPUs that were classed as not capable because they were only OpenCL 1.1 are in the process of being reinstated.
