Re: [OMPI users] FCA collectives disabled by default

[Ralph Castain]

Looking at the source code, it is because those other collectives aren't 
implemented yet :-)

[OMPI users] FCA collectives disabled by default

[Brock Palen]

We are starting to play with FCA on our Mellonox based IB fabric.

I noticed from ompi_info that FCA support for a lot of collectives are disabled 
by default:

Any idea why only barrier/bcast/reduce  are on by default and all the more 
complex values are disabled?
