NUCLEI/UNEDF Leadershipclass compu9ng ! Significant accomplishments in NUCLEI/UNEDF, achieved through leadershipclass compu9ng "Abini&o calcula9ons of C12 "Understanding the long life9me of C14 "Abini&o calcula9ons of Ca54 "Improved energydensity func9onals "Quan9fying the limits of nuclear existence ! SciDAC collabora9ons between applied mathema9cians, computer scien9sts, and nuclear physicists lead to efficient u9liza9on of leadershipclass compu9ng resources for nuclear physics problems ! Typically, > 60% of the compu9ng resources are used at leadershipclass scale (u9liza9on @ OLCF) UNEDF Contacts: H. Nam, [email protected] /J.
