Is there a command for the PCT which allows to know the communication time spent by the client to send data to the workers?

I would know if there is a command or a way to know exactly the time spent in communication, for an embarrassangly parallel routine (then, there is no communication between nodes of a cluster or local multi-core), referred to the case when the client sends data to each workers. I know that with the "mpiprofile info" there are some fields about communication, but I run it and it seems they only correspond to the intra-nodes communication, since for my simulations the value of "TimeWasted", "CommTime", "CommTimePerLab", etc... are always zero. Thank you in advance.
