Build TAU/PDT
For PDT:
./configure ; make ; make install
For TAU:
./configure -cc=pgcc -c++=pgCC -fortran=pgi -mpi -mpilibrary=-lpgbind -pdt=/lustre/medusa/biersdor/pdtoolkit-3.17/ -pdt_c++=g++ make install
Building NEK
use the pgi modules:
module load PE-pgi openmpi/1.5.1-pgi
As an example we will build and run for the 3D vortex example:
cd examples/vortex cp ../../trunk/nek/makenek . cp ../../trunk/tools/scripts/nekbmpi .
This gives us the scripts needed to build and run NEK.
First edit makenek and change the compiler to the TAU wrapper scripts:
# source path SOURCE_ROOT="<path to trunk/nek>" # Fortran compiler F77="tau_f90.sh" # C compiler CC="tau_cc.sh"
Setup your environment:
export TAU_MAKEFILE=<path to TAU>/x86_64/lib/Makefile.tau-mpi-pdt-pgi export TAU_OPTIONS="-optPreProcess -optVerbose -optRevert -optTauSelectFile=`pwd`/select.tau"
select.tau
BEGIN_FILE_EXCLUDE_LIST comm_mpi.* END_FILE_EXCLUDE_LIST
Compile
./makenek r1854a make -f makefile
There is a auto-generated makefile, any further changes can be made to this file.
Running NEK
If compiling was successful you should have nek5000' executable.
Use the nekbmpi script to run the example:
./nekbmpi r1854a <# of procs>
