OK, I cleaned up and checked in the AIO modified version of ttcp:

    gen2/trunk/src/userspace/examples/aio/ttcp.aio.c

To build it you will need libaio installed, new RHEL/Fedora distros contain
it by default, or you can download/build/install it yourself:

  http://fr2.rpmfind.net/linux/rpm2html/search.php?query=libaio

Next build ttcp.aio.c:

  gcc -I/usr/src/linux/drivers/infiniband/ulp/sdp ttcp.aio.c -o ttcp.aio.x -laio

The program has a decent help for available parameters, but here are
some reasonable defaults:

  server:

    ./ttcp.aio.x -r -l 65536 -a 20

  client:

    ./ttcp.aio.x -t -l 65536 -n 100000 -a 20 192.168.0.100
