Hi,

here is a suggestion for those of you which are interested in using ZMQ on infiniband.

There is this library called GPI2 (https://github.com/cc-hpc-itwm/GPI-2) which implements the GASPI standard. As they say on this page http://www.gaspi.de/gaspi/ :

   GASPI aims to initiate a paradigm shift from bulk-synchronous
   two-sided communication patterns towards an asynchronous
   communication and execution model. To that end GASPI leverages
   remote completion and one-sided RDMA driven communication in a
   Partitioned Global Address Space.

This could be a good starting point to implement ZeroMQ with RDMA without too much pain.

I would be happy to contribute on this, but I am not familiar at all with libzmq. So if one of you knows well the core library and wants also to do this, let's go!

by the way, thanks to all of you for developing this awesome library.

Anthony
