Abstract

We present a new concurrency abstraction and implementation technique for high-level (symbolic) parallel languages that allows significant programmer control over load-balancing and mapping of fine-grained lightweight threads. Central to our proposal is the notion of a virtual topology. A virtual topology defines a relation over a collection of virtual processors, and a mapping of those processors to a set of physical processors; processor topologies configured as trees, graphs, butterflies, and meshes are some well-known examples. A virtual topology need not have any correlation with a physical one; it is intended to capture the interconnection structure best suited for a given algorithm. We consider a virtual processor to be an abstraction that defines scheduling, migration and load-balancing policies for the threads it executes. Thus, virtual topologies are intended to provide a simple, expressive and efficient high-level framework for defining complex thread/processor mappings that abstracts low-level details of a physical interconnection.
