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-pgi

Compile
