1. Other Tools HPC Code Development Tools July 29, 2010 Sue Kelly smkelly@sandia.gov Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin Company, for the United States Department of Energy’s National Nuclear Security Administration under contract DE-AC04-94AL85000. Unclassified Unlimited Release R&A 5280854

2. HPC Toolkit from IBM source code and binary instrumentation feature a user-interface that brings all the sophisticated capabilities of binary instrumentation to the user at a high level of abstraction the functionality to collect different dimensions of performance data slated for sequoia and blue waters likely as HPCST “Action Point” Binary Instrumentation Symbolic Binary Instrumentation Standardized Data Collection Libraries Graphical Instrumentation, Visualization and Analysis pSigma HPM, … PeekPerf

3. Works by sampling an execution of a multithreaded and/or multiprocess program using hardware performance counters, unwinding thread call stacks, and attributing the metric value associated with a sample event in a thread to the calling context of the thread/process in which the event occurred. HPCToolkit supports performance analysis of fully optimized code; it even measures and attributes performance metrics to shared libraries that are dynamically loaded at run time. HPCToolkit from Rice deployed on BG/P (Intrepid), XT4/5 (Jaguar, Franklin) and Sun TACC (Ranger) http://hpctoolkit.org/

4. Paraver Parallel Visualization and Events Representation by Xavier Martorell at UPC Center for Parallelism of Barcelona (CEPBA) http://www.bsc.es/paraverhttp://www.bsc.es/paraver Designed to visualize and analyze parallel event trace files, such as those created by MPItrace for –Communication and load balance –Combined OpenMP and MPI –Hardware performance counters Usage –Compile programs with special libraries –Run programs to produce trace files –View and analyze traces Has been ported to BG/L, Cray XT

5. DDT Distributed Debugging tool http://www.allinea.com/?page=48 Has been ported to Ranger (large Sun cluster) at TACC and Franklin (Cray XT4) at NERSC supports up to 1024 processors (hello world on 220,000 MPI processes on Cray XT5 (Jaguar) apps must compile with –g similar functionality and look and feel as TotalView

6. Javelina http://javelina-cc.sourceforge.net/ Code coverage tool that uses dynamic instrumentation. Once a section of code has been executed, the instrumentation for that code is removed Obtains its line number information from the compiler-generated debugging information, so it ports easily

7. ThreadSpotter Acumem ThreadSpotter for optimizing single- and multi-threaded apps works with OpenMP and MPI apps Tutorial-like documentation http://www.acumen.com Companion product SlowSpotter analyzes memory cache performance
