A Framework For Integrated Communication And I/O Placement, Rajesh Bordawekar, Alok Choudhary, J Ramanujam Jan 1996

A Framework For Integrated Communication And I/O Placement, Rajesh Bordawekar, Alok Choudhary, J Ramanujam

Electrical Engineering and Computer Science

This paper describes a framework for analyzing dataflow within an out-of-core parallel program. Dataflow properties of FORALL statement are analyzed and a unified I/O and communication placement framework is presented. This placement framework can be applied to many problems, which include eliminating redundant I/O incurred in communication. The framework is validated by applying it for optimizing I/O and communication in out-of-core stencil problems. Experimental performance results on an Intel Paragon show significant reduction in I/O and communication overhead.
