12. 10/8/0312 k2 + Desktop Cluster new user setup common development platform “standard” NICADD physics apps no more desktop installs ample storage area shared datasets centralized authentication distributed computing

13. 10/8/0313 Plans and Schemes no more development on nicadd & individual desktops setup & packaging scripts migrate SIO-Server batch computing (fbs, pbs) physics software packages framework applications add more cluster nodes world hegemony (or at least Western hemisphere)
