Status Major Problems: Current work perl_dbd_oracle DONE Need diskcache_i versions for different root versions Version for root v5_14_00g ready Do we need more now? Some rootd versions are incompatible Current work Requirements for backup/restore wget-based releases 6 October 2010

Code Tasks perl_dbd_oracle diskcache_i rootd TAuthenticate tcsh bug Product-1 perl_dbd_oracle Moscato provided: DONE Product-2 diskcache_i New version built against v5_14_00g: TESTING Product-3 rootd TAuthenticate Partial list of incompatible versions Product-4 tcsh bug Using new ups works around problem Product-5 Two names for each product Expertise loss => need backup Tools-1 Code Browser New location, new code Tools-2 Code Browser non-CDF Browse non-CDF utilities too, optionally? Tools-3 Expanded validation suite Code-1 CosmicMods crash Not replicated yet Code-2 Uninitialized variables A couple of libraries were examined Code-3 Program Speedup Possible approaches: Code-3A look for hot spots 1) single routine Code-3B Modules run several times! 2) investigate consolidation when running Code-3C Program Speedup: partition 3) Partitioning does not seem promising Code-4 Frontierize remote? How to update/patch remote sites?
