SUMMARY:Parallel Programming Models for the Extreme Scale Era
DESCRIPTION:Students@SC Event\nStudent Program\n\nParallel Programming Mod
 els for the Extreme Scale Era\n\nKale\n\nParallel programming has always b
 een challenging. In addition to the traditional challenges of (sequential)
  programming, parallel programming has to deal with complex issues of perf
 ormance such as load imbalances, long critical paths, and communication ov
 erheads, as well as correctness issues arising from race conditions. But w
 ith the current and upcoming era in parallel computing the challenges have
  further increased. There are hardware issues of heterogeneity as well as 
 static and dynamic performance variability, and application-induced issues
  of multi-module multi-physics programming, adaptive refinements, and stro
 ng-scaling. I will explain the programming challenges these issues create,
  and describe some programming concepts and abstractions that are useful i
 n dealing with them. I will also briefly discuss some of the non-tradition
 al parallel programming approaches, in addition to the dominant MPI-OpenMP
  paradigm. The objective of this brief talk will be to convey some of the 
 excitement of this research area that I am passionate about, and to provid
 e pointers to research that you may follow later.
