Modification to Assignment Server code

We’ve made a modification to how the Assignment Server (AS) code works.  We’ve done some initial testing and are now releasing it to the backup AS (assign2.stanford.edu).  If that checks out, we’ll release it to the main AS.  The change involves how we assign SMP WUs.  If you’re seeing something strange there (eg SMP WUs’ to non-SMP clients or vice versa), please let us know in the forum (http://foldingforum.org).
