Have there been any attempts to get GPUGRID working on the newer API? From the looks of it OCL 1.2 brings a bunch of features and performance improvement over 1.1 and AMD recently released feature compatible version of its drivers for OCL 1.2. The OpenCL 1.2 beta includes the following OpenCL™ 1.2 functionality: Host access flags for memory objects enable more efficient buffer handling and provide added protection. For example, a buffer that is created as “write only” cannot be read from the host. Pattern based GPU buffer and image initialization can help eliminate need for certain buffer/image transfers Memory objects migration supports transfer of buffers prior to need New generalized image creation API Enhanced image/buffer map operations OpenCL 1.2 CPU device partition including partition of a CPU after addition to a context Generalized 1D and 2D images, image arrays, and image<-> buffer interop Libraries support including the separation of compile and link phases and the ability to compile with external symbols Kernel reflection, the ability to query a kernel’s arguments Support for printf as a built in function Source: http://blogs.amd.com/developer/2012/03/23/welcome-to-opencl%E2%84%A2-1-2-check-out-these-beta-drivers-that-contain-a-complete-opencl%E2%84%A2-1-2-solution/ |

OpenCL 1.2 does't introduce anything that we were lacking before. The problems we face are largely implementation issues: the AMD OpenCL runtime, as of version 2.4 remains unstable and - particularly on Linux - under-performing. Right now, our development effort is better spent on optimising for Kepler. I review this every Catalyst release in the hope that things improve. MJH |

As far as we crunchers are concerned.. don't put too much weight on the linux performance ;) MrS Scanning for our furry friends since Jan 2002 |

It's certainly true that Linux isn't so important for GPUGRID, but, alas, it's our dev environment. Windows only gets the love required to get the GPUGRID apps built and tested there. Doing the dev directly under Windows would be possible but gratuitously painful, and I already have quite enough ulcers. MJH |

GDF is away this week. But you bring up a good point.. if the errors were suddenly fixed, that would probably be great news :) MrS Scanning for our furry friends since Jan 2002 |

I wonder if SDK v2.7 would play nicely with this project. |

Don't hold your breath, AMD support is a long way down the list. MJH |

Whenever the show stopping bugs and performance issues are resolved. It's probably going to take a long while for the Linux SDK to catch up and since the devs use Linux mainly... Let's just say I don't expect to see AMD cards as supported until a long time from now. |

if you have an otherwise idle AMD card and want to support us, do check out www.donateathome.org MJH |

So in all seriousness, by the time AMD cards are usable here, will the 7xxx series even still exist? Reno, NV Team: SETI.USA |
