What's makes SDP so useful and why is will be sorely missed is that it does not require users to refactor existing TCP socket code, or even be in possession of the source code for that matter. Simply preloading libsdp is all need to do to convert that old, cranky tcp program to run (almost) native over InfiniBand.
SDP is used as a wire protocol rather than a API. There are several contending API's out there, including Bob Russell's Extended Socket API which could be candidates, but I would like to see the concept of the preload preserved. It's been a powerful factor in getting InfiniBand adoption. -- Richard Croucher www.informatix-sol.com +44-7802-213901 On Mon, 2012-04-23 at 13:29 +0200, Benjamin Thery wrote: > Thanks for the info. > I'll have a look at rsockets. > > On Fri, Apr 20, 2012 at 22:20, Woodruff, Robert J > <robert.j.woodr...@intel.com> wrote: > > Ben wrote, > >>Oh. > >>Is there another ULP that replaces it?
