Hi,
I was trying to use intel APS tool, as -
mpirun -np X -ppn Y aps -c mpi ./application.exe
and i came across following observation -
Messagesize(B) | Volume(MB) | Volume(%) | Transfers | Time(sec) | Time(%) |
589824 | 1.71E+08 | 26.79 | 290070590 | 220680.08 | 18.12 |
35512 | 860687.7 | 0.13 | 24236532 | 19085.79 | 1.57 |
37056 | 899539 | 0.14 | 24275124 | 19037.67 | 1.56 |
38600 | 904379.9 | 0.14 | 23429532 | 18470.59 | 1.52 |
.....
as per this report, the 290070590x transfers of the 589824 message size data took 220680.08 seconds (= ~61 hours ) but the application finished normally in ~3 hours.
(and there are more messages sizes in the report ~600 lines)
this was a run of an application with 4 process per node (10 threads per process) on 128 nodes.
Is this report incorrect or i am interpreting this incorrectly?
