This does seem an important deficiency, and a good reason to stay with 1.6 or use mpich. However, DMTCP is supposed to be able to checkpoint over TCP and Infiniband without any extra support. I'm intending to try it soon and would be interested to know any relevant experience. There used to be a note about not working over IB with some OMPI implementation detail (URC?) but I can't find that now, and the web site implies it should work. See http://dmtcp.sourceforge.net/
