API for I_MPI_ADJUST Family

Hi,

I am wondering whether Intel MPI provides a C API for changing the algorithm ID of collectives during run-time?

As far as I see in the documentation, I can only set the I_MPI_ADJUST* environment variables to choose the desired algorithm.

Perhaps there is an unofficial way of doing this?

Thanks
