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
