Process by which data about program performance are obtained from an executing program.
Profiles: time spent in different program parts.
Counters: event frequencies or cumulative times.
Event traces: occurences of various events.
Bring data into form to yield insights.
Reduce data volume.
Mean values, higher-order statistics, extract profile/counter data from traces.
Performance data are
Execution times communication costs, ...
Different processor numbers, problem sizes.
Explore data by bringing them into visual form.
