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: We present results of scaling an ab initio motif family identification system, Dragon Motif Finder (DMF), to 65536 processor cores of IBM Blue Gene/P. DMF seeks groups of mutually similar polynucleotide patterns within a set of genomic sequences and builds from them various motif families. Such information is of relevance to many problems in life sciences. Prior attempts to scale ab initio motif-finding algorithms were not successful past a handful of nodes. We solve this using a combination of mixed-mode MPI-OpenMP parallel processing, master-slave MPI parallel processing, multi-level workload distribution, multi- level MPI collective operations, and serial optimizations. While the scalability proved excellent, reaching 94% parallel efficiency on 65536 cores relative to 256 cores on a modest-size problem, the final speedup, exceeding 250,000-fold including serial optimization, enables large scale ab initio motif-finding problems to be tackled. Problems that were estimated to take decades to compute can be solved in hours.
