From: Jim Dykman <firstname.lastname@example.org> The HFI ("Host Fabric Interface") network interface is the internal cluster fabric of IBM's PERCS supercomputer. The hardware design is under US export control, so we cannot release hardware specs. There is a writeup of publically available information about the system available here: http://sourceforge.net/projects/hfidevicedriver/files/doc... hfi_core contains the resource management to set up communications paths for network traffic. Calls are provided for kernel drivers, and also for setting up direct user-space access to HFI windows. hfi_ip contains the kernel network driver. The driver has been running in the lab for several months. The full patch is around 22000 lines, so we've split out a minimal device/network driver that can send and receive through the simplest path. Once that much gets accepted we'll start adding on to it. Patches are against net-next-2.6.
