ICL Research Profile

Overview

The Distributed Tasking for Exascale (DTE) project will extend the capabilities of ICL’s Parallel Runtime and Execution Controller (PaRSEC)—a generic framework for architecture-aware scheduling and management of microtasks on distributed, many-core, heterogeneous architectures. The PaRSEC environment also provides a runtime component for dynamically executing tasks on heterogeneous distributed systems along with a productivity toolbox and development framework that supports multiple domain-specific languages (DSLs) and extensions and tools for debugging, trace collection, and analysis.

PaRSEC also enables fast prototyping DSLs to express the dependencies between tasks and provides a stable, scalable, and efficient distributed runtime so they can run on any execution platform at any scale. The underlying dataflow paradigm attacks both sides of the exascale challenge: managing extreme-scale parallelism and maintaining the performance portability of the code. The DTE award is a vital extension and continuation of this effort and will ensure that PaRSEC meets the critical needs of ECP application communities in terms of scalability, interoperability, and productivity.
