  comment = {A MIMD, shared-memory machine, with 2-processor units embedded in
  a 3-d torus. Each link is bidirectional and runs 300 MB/s. Processors are 150
  MHz ALPHA, plus 16--64 MB RAM, plus a memory interface unit. Global physical
  address space with remote-reference and block-transfer capability. Not clear
  about cache coherency. Separate tree network for global synchronization.
  Support for message send and optional interrupt. I/O is all done through
  interface nodes that hook to the YMP host and to its I/O clusters with 400
  MB/s links. I/O is by default serialized, but they do support a ``broadcast''
  read operation (but see pase:t3d-fortran). FORTRAN compiler supports the NUMA
  shared memory; PVM is used for C and message passing.}
