The OpenAFS for Windows August 2007 Status Report and updated development road map is now available:
http://www.secure-endpoints.com/talks/OpenAFS-Windows-Aug-2007-Status-Report.pdf The status report includes the most recent mock-ups which are also published at http://www.secure-endpoints.com/openafs-windows-roadmap.html The OpenAFS for Windows client since the 1.5.18 release has been updated to enhance performance by: * being more efficient searching for objects * recycling objects using algorithms that are more likely to leave useful data data in the cache * reducing the number of times data must be re-read from the file server * reducing the amount of data that must be written to the file server There have also been changes to support scalability with the goal of being able to support caches that store data from thousands of cells, volumes, status entries, and six terabytes of data. (6TB data caches will require 64-bit Windows.) The most important performance issue facing the Windows client at the moment is the inability to perform searches of AFS directories when there are negative results. This is a serious problem when search paths are involved. For example, during a build more time is spent searching for header files and libraries that is spent compiling and linking the object files. Luckily funding is available to implement local case insensitive B+ trees which will significantly reduce the clock time cost of negative directory search operations. For the complete list of changes since the 1.2 release see: http://www.openafs.org/dl/openafs/1.5.22/winnt/afs-changes-since-1.2.txt and of course be sure to read the Release Notes: http://www.openafs.org/dl/openafs/1.5.22/winnt/relnotes-frames.htm As always I encourage all organizations and individuals who wish to support the development of OpenAFS for Windows to contact the gatekeepers. Financial contributions as well as in kind assistance are necessary to ensure that proposed enhancements are implemented. Tax deductible donations may be made via the OpenAFS account operated by Usenix (a 501c3 not for profit corporation.)
