    CLInfo on 5870?

    grabner

      Hi!

      I'm curious which features of the ATI 5870 (or similar) cards are exposed in the current version of ATI's OpenCL driver. Can anybody who has such a device and the most recent ATI Streaming SDK installed please post the output of the SDK sample program "CLInfo"?

      Thanks & kind regards,

      Markus

          For 2 x 5870 in Crossfire I get this:

            And for 2 cards connected by crossfire bridges but crossfire disabled in ccc, the output is:

                Thanks a lot, your feedback is very helpful for me! I'm surprised, however, that it says "Image support: No". Even without owning one, I am very sure that the HD5870 has at least one texture unit :-), so why is it not exposed to OpenCL? Is this an issue of the current driver implementation which is going to be fixed soon? I would be glad if somebody (maybe from ATI) could comment on that!

                Thanks & kind regards,

                Markus

                Markus,
                Image support is more than just exposing texture and samplers as there are quite stringent requirements from the OpenCL spec. That being said, you can expect support in the upcoming release on 5XXX chips.

                    Thanks for this information! Will it work with the current ATI Stream SDK release (2.01), or will there be a software update, too? Is there an approximate timeline for these things?

                    Kind regards,

                    Markus

                        SDK are released around 2 months. so i think that new SDK is close by.

                        in meanwhile you can try set GPU_IMAGES_SUPPORT=1 and you get partialy supported images. by partialy a mean that only *_imagef() functions work.

                            Very interesting hint! Is there a similar hack to get partial image support on an ATI FirePro V7750? Will future versions of ATI's OpenCL driver fully support images on the V7750, or is a more recent card required for this?

                            Thanks & kind regards,

                            Markus

                        Hi,

                        If the 5870 is either 1 or 2 GB, why does CLInfo claim that the global memory size is 268435456 bytes which is about 268 mb?

                        mine is 2 GB and i get 536870912 (about 537 mb) bytes from CLInfo.

                        Also, I tried running a calculation that requires about 800mb of memory and at failed with CL_MEM_OBJECT_ALLOCATION_FAILURE. Does anyone have any explanation for this?

                        Thanks!
