Configure PETSc

export PETSC_DIR=`pwd`
./configure --with-cc=gcc --with-fc=gfortran --download-f-blas-lapack=1 --download-mpich=1

Configuring/Compile PDT and TAU

PDT:

./configure -GNU
make all
make install

TAU:

./configure -pdt=<path to PDT> -cc=gcc -c++=g++ -fortran=gnu -mpiinc=<path to petsc-3.2-p7>/arch-linux2-c-debug/include -mpilib=<path to petsc-3.2-p7>/arch-linux2-c-debug/lib -mpilibrary=-lmpichf90#-lmpich#-lmpl -DISABLESHARED
make install

Compile PETSc

export TAU_MAKEFILE=<path to TAU>/<arch>/lib/Makefile.tau-mpi-pdt
export TAU_OPTIONS='-optVerbose -optNoRevert -optTau="-rn PetscFunctionReturn -rv PetscFunctionReturnVoid\(\)" -optPdtCOpts="-D_MM_HINT_NTA=0"'
make all-legacy PCC=tau_cc.sh FC=tau_f90.sh PCC_LINKER=tau_cc.sh FC_LINKER=tau_f90.sh
make test PCC=tau_cc.sh FC=tau_f90.sh PCC_LINKER=tau_cc.sh FC_LINKER=tau_f90.sh

If you have any other examples you would like to run (for example, ex19) do the following:

cd src/snes/examples/tutorials
make ex19 PCC=tau_cc.sh FC=tau_f90.sh PCC_LINKER=tau_cc.sh FC_LINKER=tau_f90.sh
../../../../arch-linux2-c-debug/bin/mpiexec -n 4 ./ex19  -da_grid_x 20 -da_grid_y 20 -lidvelocity 1 -snes_ksp_ew -pc_mg_smoothdown 2 -pc_mg_smoothup 2

Performance results

For example a 2 processor run of ex19 you should see:
