The device driver patch for 2.6.36, hfi-utils, and an introduction to the hardware are available on the sourceforge page (http://sourceforge.net/projects/hfidevicedriver). The hardware design is under US export control, so we cannot release hardware specs. The HFI device driver allows direct user-space access to network resources; a reference library will be uploaded to http://sourceforge.net/projects/halreferencelib in the next few days. The driver has been running in the lab for several months. The user-space access is essentially complete. We are still working on IPv6, and we are now starting work on an ofed-over-hfi driver, but we'd like to start the review process without them. Jim Dykman
