TAU (Tuning and Analysis Utilities)
Category: Tools-Performance-Profiling
Description
TAU Performance System is a portable profiling and tracing toolkit for performance analysis of parallel programs written in Fortran, C, C++, Java, Python.
For more information visit TAU home page.
Use
TAU is capable of gathering performance information through
instrumentation of functions, methods, basic blocks, and statements.
TAU's profile visualization tool, paraprof, provides graphical
displays of all the performance analysis results, in
aggregate and single node/context/thread forms.
Using TAU
module load tau
This command sets TAUROOT environment variable on NICS platforms and puts the TAU compiler wrappers in your PATH.
Automatic instrumentation when compiling with the C TAU wrapper:
> export TAU_MAKEFILE=${TAUROOT}/lib/Makefile.tau-mpi-pdt # ksh syntax
> tau_f90.sh test.f
