National Center for Atmospheric Research Scientific Computing Division _A_d_d_r_e_s_s: Visitor/User Information NCAR/Scientific Computing Division P.O. Box 3000 Boulder, Colorado 80307-3000 _E-_m_a_i_l: scdinfo@ncar.ucar.edu _P_h_o_n_e: (303) 497-1225 _D_e_s_c_r_i_p_t_i_o_n The Scientific Computing Division (SCD) of the National Center for Atmospheric Research (NCAR) provides supercomput- ing resources and services that support research in the atmospheric, oceanographic, and related sciences. We emphasize facilities for the development and execution of large models and for the archival and manipulation of large datasets. o+ Cray X-MP/48 supercomputer running the Cray Operating System (COS) with 256 megawords of solid-state storage. o+ Dicomed graphical film processors capable of pro- ducing high-volume black-and-white microfiche as well as black-and-white or color 16-mm and 35-mm film. o+ Mass Storage System (MSS) using the IBM 3480 car- tridge system associated with a disk farm that provides over 100 gigabytes of disk storage. Currently, over 10 terabytes of information are archived on the MSS. o+ Xerox 4050 laser printers for text and graphical output. _________________________ The information in this section is provided in accor- dance with the copyright notice appearing at the front of this guide.

(Available to users in 1989) The Internet Remote Job Entry (IRJE) and the MASnet/Internet Gateway Server (MIGS) are SCD-developed facilities that allow the user to access SCD's computer resources while using their own local mainframe, workstation, or personal computer as a front-end. The above systems are also acces- sible directly via SCD's IBM 4381 front end computer. SCD offers: o+ Consulting expertise on the SCD computing facili- ties via the Consulting Office. o+ A user area for visiting scientists. o+ Documentation, reference materials, and the SCD Computing News monthly newsletter. o+ Training for users new to SCD's computing environ- ment. o+ Extensive software libraries for use on the Cray computers, such as IMSL, NAG, FISHPAK, SLATEC, ODEPACK, FITPACK, NCAR Graphics, and others. _N_e_t_w_o_r_k _A_c_c_e_s_s NCAR has access to several national networks using the TCP/IP protocol, including NSFNET (backbone node) and NASA's Science Network. NCAR also operates and manages the TCP/IP-based University Satellite Network (USAN), which pro- vides NCAR with high-performance direct links to user sites. NCAR has a gateway to Bitnet and SPAN. _W_h_o _C_a_n _U_s_e _T_h_e _C_e_n_t_e_r SCD's computing resources are available to scientists and researchers with NSF projects in the atmospheric, oceano- graphic, and related sciences. Accounts must be approved through SCD. Once approved, resources are allocated. Time on the X-MP/18 will be available to government agencies on a cost-recovery basis. Users with NSF grants should contact John Adams, NCAR/SCD, P.O. Box 3000, Boulder CO 90303, for an application form. June 30, 1989 NNSC Section 1.4, Page 2
