  comment = {The Convex Exemplar connects {\em hypernodes}, which are basically
  SMP nodes built from 8 HP PA-RISC CPUs, lots of RAM, and a crossbar switch,
  with their own implementation of the SCI interconnect. Hierarchical caching
  supports a global shared physical address space. Each hypernode can also have
  an I/O adapter, to which they can attach lots of different I/O devices. The
  I/O adapter has the capability to DMA directly into any memory in the system,
  even on other hypernodes. Each hypernode runs its own file-system server,
  which manages UNIX file systems on the devices of that hypernode. Striped
  file systems are supported in software, although it's not clear if they can
  stripe across hypernodes, or only within hypernodes, ie, whether (striped)
  file systems can span multiple hypernodes.}
