From: SYSTEM MANAGER Date: 04-feb-1997 17:00 College of Engineering and Technology Computer Systems Overview (Approved by College of Engineering Computer Committee) Page 1 COLLEGE OF ENGINEERING AND TECHNOLOGY 1. Digital 2100 Server Model A500MP (Open Alpha AXP) o 2 processors (CPUs) o 640MB RAM (memory) o 220GB disk o UNIX OS (Digital UNIX, version 4.0) 1.1 Compilers o FORTRAN 77, FORTRAN 90 o PASCAL o C, C++ (CC or gcc) 1.2 Applications o Editors o Text formatters o Graphics packages o International Mathematical/Statistical Libraries (IMSL) o MAPLE o Future driver for Statistical Analysis System (SAS) program o Other UNIX/TCPIP applications/management/maintenance programs 1.3 Usage o Jobs with respectively small memory requirements, but long CPU times. If a large amount of memory is needed, the Cray may perform better. Before running an extremely long job, or many jobs, it is best to attempt a quick benchmark to see if the Cray or the Alpha would be faster for the individual's own program. 1.4 Used by o Faculty and students of the College of Engineering and Technology 1.5 Note o The Digital 2100 Server is a multiprocessor system o There are a series of developer's kits for Fortran 90, Fortran 77, and C++ developers. The Fortran packages contains the software tools to facilitate porting and optimization of applications for scalar as well as parallel execution. o Network o Ethernet of GIGA switch interconnect with multiple FFDI links o ATM-ready managed by SNMP based software 1.6 Registering for an account on engunx.unl.edu o The 'register' system is a means of creating and maintaining user accounts on engunx.unl.edu. To the user it appears very similar to the 'register' system on the engrs machines. o To register into the engunx system you login as username register with password register. Page 2 COLLEGE OF ENGINEERING AND TECHNOLOGY 2. Supercomputer Cray J 916 o 6 processors (CPUs) o 1GB RAM (memory) o 37GB disk o UNICOS OS (Cray OS) 2.1 Compilers o FORTRAN 77, FORTRAN 90 o C, C++ 2.2 Usage o Large jobs (with need for a large amount of memory), large arrays, easy vectorizable - should run extremely well on the Cray. 2.3 Used by o Faculty of the College of Engineering and Technology and graduate and undergraduate students who have a faculty sponsor in the College of Engineering and Technology. 2.4 Note o The Cray is best suited to running programs which require large amount of memory. For small memory, long duration jobs, the Engineering Digital 2100 Server Open Alpha AXP is probably better suited. Before running an extremely long job, or many jobs, it is best to attempt a quick benchmark to see if the Cray or the Alpha would be faster for the individual's own usage.

IBM RS/6000 Engineering cluster (engrs) o 18 IBM RS/6000 o 2 servers 16MB, and 40MB RAM, 5GB disk each o 16 clients 16MB memory, 120 MB disk each o AIX OS (IBM UNIX) 3.1 Compilers o FORTRAN 77, FORTRAN 90 o C 3.2 Applications o Editors o Text formatters o Graphics packages o Driver for Statistical Analysis System (SAS) program o Other UNIX/TCPIP applications/management/maintenance programs 3.3 Usage o Originally purchased for undergraduate classwork, they have been used by both undergraduate and graduate students. They are primarily used for classwork, email, and network news reading. The also see use for the FORTRAN and C programs for classes, SAS submitting, graphics output, and many other 'smaller' tasks. They are well suited to short, small programs. Due to limited memory (16MB typically) they are not well suited to large memory jobs. 3.4 Used by o Faculty and students of the College of Engineering and Technology Page 4 COLLEGE OF ENGINEERING AND TECHNOLOGY 4. PC labs 4.1 Note o The College of Engineering and Technology has no PC lab at the moment. (Each Engineering department does have their own PC lab (anything between 12-50 PCs - approximately 240 PCs). o When the ground floor of the link is completed (estimated in February 1997), there will be 40+ PCs and a dual classroom/lab arrangement. They will most likely be running Windows NT 4.0. No other software has been specifically identified for them. 4.2 Usage o In general, PC labs see use as word processing, graphics, spreadheets, and other 'canned' packages and applications. FORTRAN and C programming is typically available also. Page 5 COLLEGE OF ENGINEERING AND TECHNOLOGY 5.
