“…Such interfaces are available or are being designed for a variety of systems. For Unified Parallel C (UPC) [29] and the underlying GASNet [1] library, the callback-driven interface GASP [21] provides information for tools such as the Parallel Performance Wizard (PPW) [22,27]. The upcoming tools interface [8] for OpenMP [24] will also provide a callback-driven tool interface.…”

Understanding the behavior of parallel applications that use the Message Passing Interface (MPI) is critical for optimizing communication performance. Performance tools for MPI currently rely on the PMPI Profiling Interface or the MPI Tools Information Interface, MPI_T, for portably collecting information for performance measurement and analysis. While tools using these interfaces have proven to be extremely valuable for performance tuning, these interfaces only provide synchronous information, i.e., when an MPI or an MPI_T function is called. There is currently no option for collecting information about asynchronous events from within the MPI library. In this work we propose a callback-driven interface for event notification from MPI implementations. Our approach is integrated in the existing MPI_T interface and provides a portable API for tools to discover and register for events of interest. We demonstrate the functionality and usability of the interface with a prototype implementation in Open MPI, a small logging tool (MEL) and the measurement infrastructure Score-P.

“…We use Parallel Performance Wizard (PPW) [19] as a specific software performance analysis tool to discuss integration here, although these concepts apply to other tools as well. PPW supports performance analysis for Partitioned Global Address Space (PGAS) programming models such as UPC and SHMEM as well as to message-passing models such as MPI.…”

Reconfigurable computing (RC) applications employing both microprocessors and FPGAs have potential for large speedup when compared with traditional (software) parallel applications. However, this potential is marred by the additional complexity of these dual-paradigm systems, making it difficult to identify performance bottlenecks and achieve desired performance. Performance analysis concepts and tools are well researched and widely available for traditional parallel applications but are lacking in RC, despite being of great importance due to the applications' increased complexity. In this paper we explore challenges and present new techniques in automated instrumentation, runtime measurement, and visualization of RC application behavior. We also present ideas for integration with conventional performance analysis tools to create a unified tool for RC applications as well as our initial framework for FPGA instrumentation and measurement. Results from a case study are provided using a prototype of this new tool.
