When viewing the Technical Program schedule, on the far righthand side
is a column labeled "PLANNER." Use this planner to build your own
schedule. Once you select an event and want to add it to your personal
schedule, just click on the calendar icon of your choice (outlook
calendar, ical calendar or google calendar) and that event will be
stored there. As you select events in this manner, you will have your
own schedule to guide you through the week.
You can also create your personal schedule on the SC11 app (Boopsie) on your smartphone. Simply select a session you want to attend and "add" it to your plan. Continue in this manner until you have created your own personal schedule. All your events will appear under "My Event Planner" on your smartphone.
ABSTRACT: One of the most fascinating issues in modern condensed matter physics is to understand highly-correlated electronic structures and propose their novel device designs toward the reduced carbon-dioxide future. Among various developed numerical approaches for highly-correlated electrons, the density matrix renormalization group (DMRG) has been widely accepted as the most promising numerical scheme compared to Monte Carlo and exact diagonalization in terms of accuracy. In fact, DMRG perfectly resolves one-dimensional chain like quantum systems. In this paper, we suggest an extended approach to higher-dimensional systems with high-performance computing techniques. The computing target is a huge non-uniform sparse-matrix diagonalization. In order to efficiently parallelize the numeric part, we implement a communication-step doubling together with the reuse of the mid-point data between the two steps to avoid severe bottleneck of all-to-all communications essential for the diagonalization. The technique is successful especially for clusters composed of more than one thousand cores.
