Index X - Core URL

This full URL is actually constructed by qd (and the client) from the directory URL and the core number, both of which are stored in queue.dat. It can be used to verify that the server knows the correct client OS type, and also to determine which core is required for this work unit. At present, Core_65 is Tinker (Folding), Core_78 is Gromacs (Folding), Core_79 is double-precision SSE2 Gromacs (Folding), Core_82 is PMD Amber (Folding), Core_96 is QMD (Folding), and Core_ca used to be SPG (Genome). A newer core, Core_a0 is Gromacs 33 (Folding). See also FAH Wiki: Cores

The core version which was most recently run on this unit is shown in parenthesis after the URL, if it can be determined. It is parsed by qd from the core log file, which is deleted if the unit uploads on the very first try, so on some systems which have permanent connections to the Internet, the core version will only rarely be shown at indices other than the current one.

grep "048 Web address" qd.c
                char    url[128];       /* 048 Web address for core downloads */
