Hello all,
I am new to Open MPI source code. I am trying to understand the Eager and
Rendezvous
implementation inside ompi code base. Could you please help and refer me
to the source file?
I read a bit on OMPI, then PML and BTL but I am still not sure what is
going on.
Thanks!
No, the PML UCX in OMPI is just a shim layer of translation from our API
into UCX API. The selection of the communication protocol you are
interested in is deep inside the UCX code. You will need to talk with UCX
developers about that.

Masoud,
The protocol selection and implementation in OMPI is only available for the
PML OB1, other PMLs make their own internal selection that is usually
maintained in some other code base.
For OB1, the selection starts in ompi/mca/pml/ob1/pml_ob1_sendreq.c in the
function
Hi George,
Thank you very much for your reply. I use UCX for the communication. Is it
somewhere in pml_ucx.c?
Thanks,
