API for I_MPI_ADJUST Family

Hi,

I would like to know whether the Intel MPI Library also has an API to select the algorithm for a given collective operation inside an MPI program?

As far as I understand the documentation, I can only use the I_MPI_ADJUST environment variables.

Is that correct or is there an API (perhaps undocumented)?

Thank you
