Note, too, that these variables are likely only changeable before MPI_INIT.
I didn't check these specific variables, but at least the btl_self_eager_limit variable is likely only read/used for setup during MPI_INIT. coll_tuned_bcast_algorithm may only be used before a communicator is setup (although I don't know that for sure offhand). > On Aug 14, 2015, at 1:50 PM, George Bosilca <bosi...@icl.utk.edu> wrote: > > They are considered as control variables, so use the cvar version and you > should get them. > > George. > > > On Fri, Aug 14, 2015 at 11:14 AM, Khalid Hasanov <xali...@gmail.com> wrote: > Hello, > > I am trying to use MPI_T interface to set coll_tuned_bcast_algorithm mca > parameter during run time, however I was not successful to do that. > > I wonder if is it currently supported in Open MPI. > > I had the same problem with setting btl_self_eager_limit parameter. > > The code I am using attached below. > > > Thanks. > > > -- > Best Regards, > Khalid > > _______________________________________________ > users mailing list > us...@open-mpi.org > Subscription: http://www.open-mpi.org/mailman/listinfo.cgi/users > Link to this post: > http://www.open-mpi.org/community/lists/users/2015/08/27470.php > > _______________________________________________ > users mailing list > us...@open-mpi.org > Subscription: http://www.open-mpi.org/mailman/listinfo.cgi/users > Link to this post: > http://www.open-mpi.org/community/lists/users/2015/08/27473.php -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
