8 Tuning Applications
This chapter discusses how to tune applications in the HP XC environment.
8.1 Using the Intel Trace Collector and Intel Trace Analyzer
This section describes how to use the Intel Trace Collector (ITC) and Intel Trace Analyzer (ITA) with
HP-MPI on an HP XC system. The Intel Trace Collector/Analyzer were formerly known as VampirTrace
and Vampir, respectively. This section addresses the following topics:
• “Building a Program — Intel Trace Collector and HP-MPI” (page 73)
• “Running a Program – Intel Trace Collector and HP-MPI” (page 74)
• “Using the Intel Trace Collector and Intel Trace Analyzer” (page 73)
• “Visualizing Data – Intel Trace Analyzer and HP-MPI” (page 77)
The following Intel Trace Collector/Analyzer documentation is available on the HP XC system after Intel
Trace Collector/Analyzer is installed:
• Intel Trace Collector Users Guide — located on the HP XC system at:
/ITC/doc/Intel_Trace_Collector_Users_Guide.pdf .
• Intel Trace Analyzer Users Guide — located on the HP XC system at:
/ITA/doc/Intel_Trace_Analyzer_Users_Guide.pdf
8.1.1 Building a Program — Intel Trace Collector and HP-MPI
HP-MPI is MPICH compatible if you use the HP-MPI MPICH scripts which are located at:
/opt/hpmpi/bin
. The HP-MPI MPICH scripts are:
• mpicc is replaced by mpicc.mpich
• mpif77 is replaced by mpif77.mpich
• mpirun is replaced by mpirun.mpich
In summary, mpixx becomes mpixx.mpich.
For further information, see the Intel Trace Collector Users Guide. This document is located on the HP XC
system at the following location:
/ITC/doc/Intel_Trace_Collector_Users_Guide.pdf
