The NERSC provides state-of-the-art computational, network,
and file storage resources including four Cray
supercomputers-a Cray XMP-22, a Cray-2 4/64, a Cray-2 4/128,
and a Cray-2 8/128. All four Crays use the CTSS time-share
operating system. This system also currently provides more
than 150 UNIX utilities and is becoming POSIX compliant.
The center operates twenty-four hours a day, seven days a
week.
Archival storage includes an online fully automated storage
system with 200 gigabytes of high-speed disk storage, and a
magnetic tape cartridge system with a total of 3.6 terabytes
of slower access storage. The slowest accesses are still
under three minutes.
An online information retrieval system is provided, offering
more than 23,000 pages of documentation on use of the
center. Printed hardcopy of all information is also avail-
able to all users. The BUFFER is published as a monthly
newsletter. Short notes in the form of printed summaries
are available. Electronic bulletin boards are available for
information about specialized topic areas. A NEWS capabil-
ity is provided for daily or short-term information.
Several consultants are available during normal working
hours for individual help.

The NERSC supports TCP/IP access and limited (interactive
only) DECnet network access in addition to its own "NSP"
protocol suite. Access is available through ESnet, the
Internet, the Energy Sciences DECnet, Bitnet for electronic
mail, TYMNET, and via dial-up modems.
The NERSC also operates ESnet, a T1-based backbone network
supporting both IP and DECnet.
