Message-ID: <570EE19A.4040301@systemfabricworks.com> (raw)
In-Reply-To: <1828884A29C6694DAF28B7E6B8A82373AB0416C3-P5GAC/sN6hkd3b2yrw5b5LfspsVTdybXVpNB7YpNyf8@public.gmane.org>

There were some presentations that discussed IB Routing and the 
challenges/availability at the recent Open Fabrics Workshop in 
Monterey.  Here is a link to a site that has both the slides and the 
videos (some chose not to allow video) from the workshop 
http://insidehpc.com/2016-open-fabrics-workshop-video-gallery/

Regards,

Kevin
