METU Computer Center (METU CC) provides a comprehensive range of facilities and services to meet the computational and communicative needs of the academic and administrative units of the university. METU CC, ahead of all others, has been successful in keeping its hardware and software park up-to-date since 1960. We believe that the table below providing the historical development of computer technology of METU CC will reveal interesting information.
1974 IBM 370/40 was replaced with an IBM 370/145 with 384 KB memory, 2 disks (3330, 2*100 MB), 1 punch machine(2540), 1 tape reader (3505), 2 line printers (1403) and 1 system console (321) that were hired.
1990 IBM 3090/180S started servicing with VM/XA operating system. The system had 1 vector processor, 128 MB memory, 22.5 GB disk (3380), 135 colorless (3191) and 15 color (3192) terminals, 2x4245 (20001 pm) line printers, 2 magnetic tapes (6250 bpi) and 2 cartridge drivers (32000 bpi).
METU CC and the university campus were connected to EARN-BITNET with IBM 3090/180S.
3 terminal rooms started serving in Mechanical Engineering, Civil Engineering and Physics departments.
Token ring (16 MB/s) was established on campus and connected to mainframe computers from 16 locations.
HP/9000 817S was installed with 16MB memory, and HP-UX operating system.

The first Internet connection from METU to the Netherlands by X-25 was established.
Turkish Internet Connection (TR-NET) was established between METU, Ankara and NSF Washington DC. A line of 64 kbps was established between METU and NSF. This connection served the whole country.
2 PC rooms in the first and second dormitories opened to help use Novell network operating system.
UNISYS B6930 system was removed.
Sun Server was installed with a 32MB memory and 4GB disk.
UNISYS A9F was closed to the access of academic staff and users.
METU-NET was expanded to 22 access points.
1994 IBM 3270 terminal rooms at Mechanical Engineering Department, Civil Engineering Department and Physics Department were converted to PC rooms. 83 PCs located in these rooms served by Novell Netware server and were connected to METU-NET via multi-protocol routers. Tatung 1041 server 32MB memory was bought with 1GB disk. IBM SP2, the first Supercomputer in Turkey which entered the top 500 list all around the world was used in METU, (http://www.top500.org/site/1145 376th place).
IBM 3090/180S +VF aged after five years' work and was replaced by three IBM 590S File Servers and one IBM SP2 (with 8 nodes) Compute Server, all running under AIX (IBM UNIX operating System).
The Compute Server SP2 (Scalable POWER2parallel Systems) is composed of 8 nodes with POWER2 processors. Serial, batch, parallel and interactive workloads can be concurrently processed on SP2 (nautilus). It is capable of processing compute-intensive jobs. There are three POWERserver 590s that are planned to provide file services as well as the processing power that can easily support the usual workload at the university. POWERserver 590 also has POWER 2 processors. Two of the POWERserver 590s(rorqual and narwhal) are connected directly to 80 gigabytes of RAID disk. Three POWERserver 590s and four nodes of SP2 are connected to FDDI network.
Systems were connected to the METU backbone (METU-NET) through the token ring cards that are on two of the POWERserver 590s. There are two token-ring cards on each machine to increase the availability of the system's connection to the METU backbone AIX operating system that runs on the systems.
1995 IBM Scalable POWERparallel System (SP2) was installed and offered to service. This system consists of 8 nodes, each having 64 MB memory and 1 GB disk. This system serves users who need high performance computing and dense processor usage.
1996 HP 800/E25 and IBM RISC 6000 POWERserver J30 and G90 model systems were bought and made available for usage, in order to increase the processor power of installed systems. Additionally, Robot Tape Library systems were installed to make backing up more reliable and safe.
1997 256 MB memory is added to IBM RISC 6000 POWERserver J40, the number of processors in IBM RISC 6000 POWERserver G40 is increased from 2 to 4 and, 256 MB memory is added to it, 128 MB memory is added to IBM RISC 6000 POWERserver 590, and 64 MB memory is added to each of the 8 nodes of IBM RISC 6000parallel SP2 and 4.5 GB disk is added to it. At the end of 1997, 4 new Unix-based systems were purchased.
In order to convert the METU local network to ATM, Switches between Economic and Administrative Sciences, CC, Mechanical Engineering and Industrial Engineering began to be used for test purposes.

The efforts to improve the e-mail services provided by our university has now matured, and as a consequence of these newly adopted improvements by METU CC on central Unix servers which serve 24 hours and 365 days, the e-mail addresses which belong to the students, the academic and administrative personnel, have been changed with a continuous effort to usernamemetu.edu.tr since the process was launched in April.
Due to the insufficiency of the ULAKNET connections which connect the academic institutions and since TTNET connections are now made available, the investments have been made to connect METU to this network structure. In this respect, the 34 Mbyte/sc connection between the Balgat switch and METU, has been activated after the necessary configurations are completed. The capacity of ULAKNET connection has been multiplied by 4 Mbyte/sc via adding a 2 Mbyte/sc connection. Providing an additional TTNET connection with a capacity of 8 Mbyte/sc , these recent efforts have accumulated to a total internet connection capacity of 12 Mbyte/sc. To answer the intense demands of the the users and to offer a problem-free service, investments are being made to build ISDN/PRI MODEM connections of digital technology with a capacity of 60 lines.
3 new laboratories serving for multimedia purposes have been built within the project called BADE to facilitate the learning of basic package programs by the prep school students and freshmen. As a consequence, the total number of the PC rooms is now 16 and the total number of the PCs in these rooms have reached 423.
Within the framework of the agreement which is entered into with Yildiz University and Hacettepe University in 1997, the projects of automation have been carried out , new programs for the specific needs of university have been written and they are now being used. Later in time, after some alterations and regulations on these projects, a package has been developed to build Registrar's Office Information System(OİBS) project. During spring semester grading period, this system has been started to be used in our university.
The Circulation Module (Lending books) of the VTLS System is now available to all library users. Therefore, the library's card system is now being gradually abandoned.
11 educational seminars particularly concerned with the users were held and a total of 1242 people had participated in them.
