            The computer environment at the Los Alamos National  Labora-
            tory   (LANL)   is   supported  by  a  multi-security  level
            Integrated Computing Network (ICN)  which  integrates  large
            host  supercomputers,  a  file  server,  a  batch  server, a
            printer and graphics output server and numerous  other  gen-
            eral  purpose and specialized systems.  Among the latter are
            experimental machines such as the Intel Hypercube,  the  FPS
            T-series  machine  and two Connection Machines.  In addition
            to unclassified network access, remote, secure  access  over
            LANL installed encrypted data links is supported for classi-
            fied computing up to the Secret level for NSI, FRD and CNWDI
            information  categories.   Current (August, 1989) production
            host systems include two Y-MP/832s, two  X-MP/416s,  one  X-
            MP/48,  one X-MP/24 and an X-MP/14.  The latter machine runs
            UNICOS while the others run CTSS.

            External networks  connected  to  the  ICN  include  MILNET,
            ESNET,  NMFENET, HEPNET, BITNET, CSNET, SPAN, NSFNET, NWCNET
            and TELENET.  In addition, LANL  maintains  a  national  T-1
            backbone network supporting point-to-point, unclassified and
            secure data links to major users of the ICN.  Dial-in access
            at  up to 9600 bps is also supported for both classified and
            unclassified connections.
