reach 1 GByte/s throughput per link, especially if you can make a cut-through router
so that you don't have to touch internal memory bandwidth for through traffic.

Right now Parallella support is available in a pre-compiled package available for download from www.browndeertechnology.com/coprthr_download.htm (github disabled downloads so we moved the binary downloads here). These builds are being tested on a prototype board and should be considered beta in advance of the next official package release. The source code can be found on github under the current branch. Note that the default on the github project is still 1.4-stable - for Parallella you do not want that branch. Now, unless you have one of the early boards its not clear how easily one can test these builds. We are looking at a way to allow build and test for Parallella without a board to expand accessibility for developers who want to experiment with Parallella programming in advance of a board.
If interested in this MPI "lite" code this is still experimental and has not been merged into current. Sorry.
If you have trouble with building COPRTHR SDK please send questions to support@browndeertechnology.com
The build is tested on a range of platforms and should not require many symbolic links, etc. However, its difficult to catch every platform configuration. We always appreciate feedback to improve the build configuration.

seems libelf is the key.

I was able to get the COPRTHR SDK to install on 64-bit Linux Mint Debian Edition, but it required installing a different version of libelf, as seen below.
In the README.txt, it states the following:
"Please take note that libelf 1.x branch found on most Linux distributions is not a valid substitute for libelf-0.8.13 since they lack the required features and exhibit undocumented broken behavior."
The README.txt file has a to this version of libelf, which you can download and install following the steps listed in the libelf INSTALL.txt file. This will install a different version of libelf, without stepping on your existing version.
After doing this, you should be able to configure, make, and install the COPRTHR SDK, doing the following:
./configure --with-libelf=/usr/local
make
sudo make install

You can download the COPRTHR SDK from the link below and the installation instructions can be found in the COPRTHR Primer.

I talked to a bunch of people about this in the past and received all kinds of reasons why MPI wasn't a good fit for Epiphany. You actually went ahead and implemented a basic MPI programming model in less than a week. Mind boggling! I thank my lucky star that I typed in "GPL OpenCL" in a Google search a year ago to find Brown Deer Technology.
