Here's what's new in the 6.20 client:

• Added Forums to systray menu.
• Support cpu affinity by default, this is related to an nVidia problem and awaits core-side changes.
• Add additional parameters field in advanced preferences - no more shortcut editing!!!
• UNSTABLE_MACHINE count reset after a correctly finished WU, for long-running systems
• Open configuration dialog box when invalid settings detected
• Fixed core launch directory which caused auto-upgrades to fail if core was present in "Program Files"
• Added additional advanced config options to console clients
• Added MachineID selector in systray gui
• Client shows PRCG on results upload
• Passkey now validated for hex content
• Moved service installation to advanced config to prevent inadvertant use
• Log date and time when automatically attempting to upload results.
• Correctly restore system tray icon when shell (explorer.exe) crashes
• Significantly improved queueinfo
• Multiple copies of the client can no longer be started with the same "start in" dir
• Automatically increase packet limit to max size for results that are too large
• Failed uploads will be attempted again using alternative upload port (8080->80 and 80->8080)
• Removed spurious "benchmarking..." messages
• Added extra_parms support to console clients
• Extra parameters are validated at configuration and launch time. Invalid settings will force reconfiguration
• Fixed and updated service installation to allow use of working directories
• Added ATI FireStream 9170 detection
• Compressed Vista icon to reduce size of executable (saves ~ 200kb)
• Updated MyFolding.html to match folding.stanford.edu style

• The FireStream 9250 supports double precision floating point operations in hardware
• Up to 8 GFLOPS per watt of single precision performance potential
• Familiar 32 and 64 bit Linux and Windows environments
• High level tools from multiple 3rd party developers
• C-like development environment via extensions to open source Brook+
• Low level access to hardware via open IL and ISA specifications in AMD Stream’s CAL
• Stream software supports multiple GPUs per system
• FireStream leverages commodity GPU components designed for PC gamers resulting in a reliable GPU and memory roadmap

• 1GB on-board GDDR3 memory
• Memory export
• Double precision floating point support
• <150W power consumption; 55nm process
• Asynchronous DMA
• PCIe 2.0 x16 interface
• BIOS settings optimized for stream processing
• API and OS Support
• Open system approach with AMD Stream SDK

AMD is a founding and contributing member of the OpenCL working group in The Khronos Group, and has consistently been one of the most vocal and active proponents of the standard. AMD is committed to getting this valuable new technology into the hands of programmers as quickly as possible, and is rapidly evolving its free ATI Stream SDK to make it happen. AMD is making good progress on its OpenCL-compliant offering and plans to release a developer version of the ATI Stream SDK with support for OpenCL 1.0 for content developers in the first half of 2009. Working from early specifications of OpenCL, AMD’s engineering team has already started running code on its initial implementation.

AMD also continues to improve its Brook+ tools and plans to provide a transition path for those who want to port their Brook+ code to OpenCL. Brook+ is an open source, high-level programming framework provided by AMD as part of the free ATI Stream SDK.
Building on the significant enhancements of ATI Stream SDK 1.3, version 1.4 is being designed to add finer grain data type support, graphics API interoperability, multi-GPU support and thread-level data sharing to Brook+. It is also being enhanced to add improved support for the ATI Radeon HD 4870 X2 graphics cards and to include support for several ATI FirePro 3D graphics accelerators. AMD expects to release version 1.4 of the ATI Stream SDK in the first quarter of 2009.
