Unified Parallel C Profiling Interface Proposal

Due to the wide range of compilers and the lack of a standardized profiling interface, writers of performance tools face many challenges when incorporating support for Unified Parallel C (UPC) programs. This document presents a preliminary specification for a standard profiling interface that attempts to be flexible enough to be adapted into current UPC compiler and runtime infrastructures with little effort, while allowing performance analysis tools to gather much information about the performance of UPC programs.
