SPECIAL FACILITIES AND PROGRAMS / 35 to the central processor include IBM 3350,3380, and 3390 disk drives, and 9-track, 7-track, and cartridge tape drives. Telecommunication services are supported by IBM 3705 and IBM 3725 communications controllers. IBM 7171s provide dial-up protocol conversion for selected ASCII workstations so that they can emulate full-screen, 3270- type terminals. Input and Output.-NERDC provides input and output facilities in the form of magnetic tapes and disks, impact and laser printers, graphics, and computer output microfiche (COM). Two IBM 4245 high-speed printers and two IBM 3820 laser printers provide printed output. Graphics output is available through a Versatec Electrostatic Color Plotter and IBM 3820 laser printers operated at NERDC's central site inthe BryantSpace Sciences Research Building. NERDC supports job submission/retrieval and interactive process- ing through more than 2,000 interactive terminals and microcomputers that emulate terminals. These terminals can access NERDC's timesharing systems (TSO, VM/CMS, AIX, and CICS/VS) for editing, interactive program execu- tion, and batch job submission. Software.-The major production languages include ASSEMBLER, COBOL, VS FORTRAN, PASCAL, PL/I, and VS/APL. Student-oriented languages supported in selected environments include ASSIST, PL/C, WATBOL, WATFIV, Waterloo C, and Waterloo PASCAL. File management systems and report generators include EASYTRIEVE, MARK IV, and PANVALET. IBM's DB2 is NERDC's primary data- base management system. TPX allows concurrent interac- tive sessions from one terminal. Other primary software includes statistical packages (BMDP, SAS, SPSSX, and TROLL), text-formatting programs (TeX; WordPerfect 4.2 for CMS; and IBM DCF and Waterloo SCRIPT, both with spell-checking and formula-formatting capabilities), librar- ies of scientific and mathematical routines (ESSL and IMSL), graphics programs (GDDM, Versatec plotting software, PLOT79, SAS/GRAPH, and SURFACE II), financial spead- sheets and modelers (Supercalc, and IFPS), vector facility software, mini- and microcomputer supportvia file-transfer capabilities, the LEARN Grwth Format computer-based training system, local and IBM utilities, and special-purpose languages. Research Computing Initiative and Numerically Inten- sive Computing Support.-NERDC and IBM offer a signifi- cant but limited amount of free computing time to UF and SUS faculty members to develop programs that use the high-performance features of the IBM 3090 600 and its six vector facilities. The Faculty Research Computing Service Initiative Allocation Committee receives and evaluates proposals for computing support within a two-year period that began March 1990. NERDC activities that support numerically intensive computing include periodic work- shops, aid in converting programs to take advantage of the vector processors, and advice on the design of new NIC software, and more. To request guidelines, application forms, or additional information, call NERDC at 392-2061. LUIS.-LUIS (Library User Information Service) is the online card catalog of the SUS libraries. There are LUIS catalogs for each state university system library. The state legislature has funded access to LUIS through the Florida Center for Library Automation (FCLA). Call 392-9020 for information about obtaining free identification numbers for using LUIS. Additional Information.-More information is available through NERDC's annual Guidebook, NERDC's newslet- ter, /Update, NERDC documentation, NERDC Information Services at 112 SSRB, (904) 392-2061. Center for Instructional and Research Computing Activities (CIRCA) Services available to graduate students include consult- ing; documentation; programming and analysis; database design and implementation; statistical consultingand analy- sis; noncredit computer courses; thesis production support; VAX/VMS computing; Unix computing; IBM mainframe accounts; mainframe printing; supercomputing access; and the use of interactive terminals, microcomputer laborato- ries, and microcomputer classrooms. For instructional purposes, CIRCA operates a Digital Equipment Corporation VAX cluster and a Digital Equip- ment Corporation RISC Unix computer. These computers can be accessed from CIRCA-supported public terminal facilities, dial-up terminals and microcomputers, and com- puters on the campus network. Several programming languages and packages for mathematical and statistical analysis are available. For graduate students, accounts for sending and receiving electronic mail on national networks are also available. Instructors whose courses require the use of CIRCA's VAX/VMS or Unix computers can apply for class accounts. Separate VAX/VMS accounts are available at no charge for students' personal use. All accounts are restricted to a moderate amount of disk space and CPU time and may not be use for research, commercial enterprises, support of campus organizations, or administrative computing. Ap- plications for these accounts are available in the CIRCA offices, E520 Computer Sciences and Engineering (CSE). IBM mainframe computing services are provided by the Northeast Regional Data Center (NERDC), located on the University of Florida campus. CIRCA distributes NERDC accounts to University of Florida students and faculty for instructional use; research accounts are distributed through individual departments. NERDC services can be used from CIRCA terminal and microcomputer facilities, from dial-up terminals and microcomputers, and from computers on the campus computing network. Mainframe printing is also available at several campus locations. For more informa- tion about NERDCfacilities and services, see the subsection of this catalog entitled "Northeast Regional Data Center" or visit the CIRCA consulting office, E520A CSE. CIRCA microcomputer labs are availableto University of Florida students, faculty, and staff for academic and per- sonal use. These labs are equipped with Apple Macintosh, IBM, and IBM-compatible microcomputers. Dot-matrix and laser printers are available in most microlabs; plotters and optical scanners are available at some locations. In addition, several microcomputer classrooms can be re- served for academic courses. Instructors may apply for reservations at CIRCA, E520 CSE. Additional information about CIRCA and NERDC ser- vices is available from the CIRCA consultant in E520A CSE, University of Florida, 392-0906. UNIVERSITY LIBRARIES The Libraries of the University of Florida form the largest information resource system in the state of Florida. While the collections are extensive, they are not comprehensive and graduate students will find it useful to supplement them through a variety of services and cooperative programs drawing upon the resources of many other libraries. The following entry describes the UF libraries, local collection strengths and the physical distribution of collections among
