I was looking to preconnect all MPI processes to remove some weird
behaviors. As I did not remembered the full name I hope to get that from
the ompi_info.
$ ompi_info -a -l 9 | grep preco
MCA mpi: parameter "mpi_preconnect_all" (current value:
"false", data source: default, level: 9 dev/all, type: bool, deprecated,
synonym of: mpi_preconnect_mpi)
so mpi_preconnect_all is a deprecated synonym to a non-existing parameter.
So be it!
I then added "mpi_preconnect_mpi = true" to my
$(HOME).opemmpi/mca-params.conf file.
ompi_info -a -l 9 | grep preco
MCA mpi: parameter "mpi_preconnect_all" (current value:
"true", data source: file ((null)), level: 9 dev/all, type: bool,
deprecated, synonym of: mpi_preconnect_mpi)
While the change has been detected, the MCA system somehow got confused to
where this change is coming from (the source file is (null)). Not very user
friendly.
