15. KIHYEON CHO CENTER FOR HIGH ENERGY PHYSICS SAMGrid demo was showed at SC2002.  6 institutes (KNU, Toronto, RAL, Rutgers, Texas Tech, Glasgow) were involved for CDF experiment.  At KNU, 12 CPUs were allocated for SAM Grid Demo UCSD made testbed for DCAF. KorCAF(DCAF in Korea) is the first for analysis farm at CDF experiment as DCAF For the first step, to use the KorCAF as MC production farm. Later, real data… Prepare for SC2003 Demo for SAMGrid DCAF Activities
