Using Intel VTune on Nehalem cluster

Load the necessary module. For example:

module load compiler/intel 
module load performance/vtune # set up VTune environment
module load mpi/impi          # if MPI needed 

Compilation example:

ifort -g -O2 prog.f90

Analyzing MPI applications:

 mpirun –n4 amplxe-cl -c hotspots –r my_result -- path_to_my_app

Using Intel VTune on Cray machines

Load the necessary module. For example:

module swap PrgEnv-cray PrgEnv-intel # set up MPI environment too 
module load performance/vtune        # set up VTune environment

Compilation example:

ftn -dynamic -g -O2 prog.f90

Analyzing MPI applications:

 aprun –n4 amplxe-cl -c hotspots –r myResult-@@@{at} -- path_to_my_app
