Thread migration on heterogeneous systems via compile-time transformations

Abstract

Describes a technique to provide multi-threading an an enhanced C language. In contrast to the traditional design of a thread library, which usually utilizes a few lines of assembly code to effect context-switching between threads, the technique we use is based on compile-time program transformations and a run-time library. Since this approach transforms a thread's physical states into logical forms, thread migration in a heterogeneous distributed environment becomes practically feasible. Performance measurements of the current implementation are reported.
