[Mpi3-ft] docs on CP/R with RDMA fabrics

[Mike Heffner]

All,

Attached are the documents I promised during the previous conference call.

The IPDPS 2007 paper gives a technical description of the Availability 
Services product (known academically as "DejaVu") including the online 
logging algorithm used for BSD socket applications. It also includes 
some performance numbers from previous experiments with our RDMA MVAPICH 
implementation.

The avs_mpi_integration.pdf document provides a brief description of the 
interfaces that were required to integrate a userlevel CP/R framework 
with MVAPICH/RDMA. This provides an insight into what we required to 
integrate with a real-world RDMA MPI stack to provide CP/R with very 
little overhead.

The third document is one I wrote this afternoon to propose an 
asynchronous, quiescence interface. It is similar to Joshua's proposal 
on the wiki, but provides an asynchronous, driver-level version that our 
solution requires for application transparency.

I will try to get some of these onto the wiki as well.


Cheers,
