Howto

Timing using the build-in facilities can be done with

> /usr/bin/time -v

Additionally, the DAMASK process can be attached to core X (X from 0 to N-1) with

> taskset -c X

Hence, to run the example on the second core, type the following commands

> export DAMASK_NUM_THREADS=1
>  /usr/bin/time -v taskset -c 1 DAMASK_spectral -l tensionX.load -g 20grains16x16x16.geom

Intel VTune Amplifier

The Intel VTune Amplifier is part of the Intel Parallel Studio XE. To run the GUI, type

Spectral Solver TAU Analysis

TAU plain installation

install to a directory referred as $TAUDIR

MISSING: INSTALLATION OPTIONS

set the following parameters

variable	setting	meaning
$TAU_OPTIONS	'-optShared -optPreProcess -optCompInst'	Use shared library version; Preprocess the source code before parsing; Use compiler-based instrumentation
$TAU_MAKEFILE	$TAUDIR/x86_64/lib/Makefile.tau	Setting path of makefile of TAU
$LD_LIBRARYPATH	$TAUDIR/x86_64/lib	Setting TAU's library path
$TAU_PROFILE	1	Enables profiling

add to your Makefile

• LIBRARIES +=-lz -ldl
• LIB_DIRS +=-L$TAUDIR/lib/shared
• @rm -rf *.pp.f90 (at the "clean" target)

Compile the code with

> make COMPILERNAME=$TAUDIR/x86_64/bin/tau_f90.sh F90=gfortran SUFFIX=-D__GFORTRAN__

Associated TAU's files created after running DAMASK with those certain parameters above:

tautrace.[node].[context].[thread].trc	the trace file for each processor or node
profile.[node].[context].[thread]	the profile file
events.[node].edf	event file for each processor

To view the trace with JUMPSHOT, do the following:

tau_treemerge.pl; tau2slog2 tau.trc tau.edf -o app.slog2; jumpshot app.slog2
