Computational resource availability often changes during the course of execution of an application. This is especially true in modern multi-user cluster environments where users can run many high-performance applications simultaneously which share resources such as Processing Elements (PEs), I/O, main memory, network. In such a scenario, it would be greatly(More)
We report the microscopic origins of the anomalously suppressed beta decay of ¹⁴C to ¹⁴N using the ab initio no-core shell model with the Hamiltonian from the chiral effective field theory including three-nucleon force terms. The three-nucleon force induces unexpectedly large cancellations within the p shell between contributions to beta decay, which reduce(More)
The UNEDF project was a large-scale collaborative effort that applied high-performance computing to the nuclear quantum many-body problem. UNEDF demonstrated that close associations among nuclear physicists, mathematicians, and computer scientists can lead to novel physics outcomes built on algorithmic innovations and computational developments.
