20 | ! Description: |
---|
21 | ! ------------ |
---|
22 | ! Analysis and output of the cpu-times measured. All PE results are collected |
---|
23 | ! on PE0 in order to calculate the mean cpu-time over all PEs and other |
---|
24 | ! statistics. The output is sorted according to the amount of cpu-time consumed |
---|
25 | ! and output on PE0. |
