Hello.
I want to study ibverbs,rdma. I have application that use tcp/ip for
transfer data.
I want to add rdma support,avoiding usage IPoIB. So I want to write
app that can find and connect to other nodes via guides.
Does somebody share for me some links or how can I find it?
Thanks

THanks! As i understand i need kernel for example 3.14... =) and librdmacm 1.0.19 or later and use rsockets to replace tcp/ip. How about resolving? Sorry i'm try to take all pieces =). For example i see that rdma_getaddrinfo can resolve address, but as i see http://manpages.ubuntu.com/manpages/raring/man3/rdma_resolve_addr.3.html i need ipoib. In case of pure RDMA network without IP as i understand i need to check opensm sources? whether there is somewhere the minimum example how to work with guid of ports without use ipoib ? -- Vasiliy Tolstov, e-mail: v.tolstov-+9FY0jupvH6HXe+LvDLADg@public.gmane.org jabber: vase-+9FY0jupvH6HXe+LvDLADg@public.gmane.org -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 10+ messages in thread
