I just read over the proposal and I still don't see a detailed definition of quiescence. I know what it means when we're talking about checkpointing at the kernel-level(BLCR) or user-level(libckpt) or the application level(C3) and I can figure out what it means when the checkpointer works at the virtual machine monitor level, though that also depends on how well the VMM checkpointer supports the machine's network card. However, what does the spec mean? The draft spec doesn't provide any details and my concern is that the spec can never provide enough details without going into deep details of the network hardware and software stack.

I just posted a first draft of the Quiescence MPI interface proposal. The wiki page is here: http://svn.mpi-forum.org/trac/mpi-forum-web/wiki/Quiescence

Let me know what you think. Sorry it took so long to post.

Cheers, Josh
