NUCLEI/UNEDF Leadership-‐class compu9ng
! Significant accomplishments in NUCLEI/UNEDF, achieved through leadership-‐class compu9ng
" Ab-‐ini&o calcula9ons of C-‐12 " Understanding the long life9me of C-‐14 " Ab-‐ini&o calcula9ons of Ca-‐54 " Improved energy-‐density func9onals " Quan9fying the limits of nuclear existence
! SciDAC collabora9ons between applied mathema9cians, computer scien9sts, and nuclear physicists lead to efficient u9liza9on of leadership-‐class compu9ng resources for nuclear physics problems
! Typically, > 60% of the compu9ng resources are used at leadership-‐class scale (u9liza9on @ OLCF)
