Los Alamos National Laboratory Integrated Computing Network _A_d_d_r_e_s_s: Los Alamos National Laboratory Attn: C-DO, External Computing B260 Los Alamos, NM 87545 _E-_m_a_i_l: skf@lanl.gov _P_h_o_n_e: (505) 667-9463 _D_e_s_c_r_i_p_t_i_o_n 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. _N_e_t_w_o_r_k _a_c_c_e_s_s 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. _________________________ The information in this section is provided in accor- dance with the copyright notice appearing at the front of this guide.
