Communication Topology : point to point data flow is missing ?

[Qinghe12]

I use IPM-2.0.6 to stat MPI communication behavior while Communication Topology is missing when ipm_parse to html ?

Hi pass the -force-topology flag to ipm_parse and try again There is a cut off in the code of 1025 mpi ranks to prevent the time taken by ipm_parse increasing too much. regards,

@njwright I'm sorry to say that Using flag -force-topology can't solve it.

I found that Communication Topology module consists of some item in index.html as following：

align=left bgcolor=lightblue
a name="ct"
Communication Topology : point to point data flow
.....
img src="img/mpi_topo_data_tot.png"
....
....
href="img/mpi_topo_data_send.png"data sent
href="img/mpi_topo_data_recv.png"data recv
href="img/mpi_topo_time.png"time spent
href="map_data.txt">map_data file
href="map_adjacency.txt">map_adjacency file
...

only mpi_topo_time.png can be found in img directory While other img missing.
when index.html opened, the Communication Topology shows none

Hello @Qinghe12,
to have the Communication Topology plot you must use the C ipm_parser that is only built with --enable-parser. Otherwise it’s the perl parser that is placed in the installation folder.
You will also need mxml https://github.com/michaelrsweet/mxml. The latest version didn't work for me, I used v2.11 instead.
