DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: There are several challenges in programming applications for large supercomputers: exposing concurrency, data movement, load imbalance, heterogeneity, variations in application’s behavior, system failures etc. Addressing these challenges requires more emphasis on the following important concepts during application development: overdecomposition, asynchrony, migratability, and adaptivity. At the same time, the runtime systems (RTS) will need to become introspective and provide automated support for several tasks, e.g. load balancing, that currently burden the programmer.=0A=0AThis tutorial is aimed at exposing the attendees to the above mentioned concepts. We will present details on how a concrete implementation of these concepts, in synergy with an introspective RTS, can lead to development of applications that scale irrespective of the rough landscape. We will focus on Charm++ as the programming paradigm that encapsulates these ideas, and use examples from real world applications to further the understanding.=0A=0ACharm++ provides an asynchronous, message-driven programming model via migratable objects and an adaptive RTS that guides execution. It automatically overlaps communication, balances loads, tolerates failures, checkpoints for split-execution, interoperates with MPI, and promotes modularity while allowing programming in C++. Several widely used Charm++ applications thrive in computational science domains including biomolecular modeling, cosmology, quantum chemistry, epidemiology, and stochastic optimization.
