Computer
Services
The Computer Services Group is responsible for designing, implementing,
and maintaining the Chemistry Division's in-house central computer systems
and networks. The computing needs are supported by MicroVAXs, a DEC 3000
Mod 400, IBM RS/6000s, and several Macintosh and IBM compatible computers.
In addition, the network consists of four DEC LSI-11 computers, 25 UNIX
computers, and over 150 personal computers. This network of computers
is connected to the Laboratorywide Fiber Distributed Data Interface (FDDI)
network. The FDDI interface extends the local network to worldwide Internet.
The central computers provide the power for general computation and
graphics activities. Some of these computers, along with Macintosh and
PC servers, provide electronic mail, file, and printer services. The LSI-11
systems are used for experiment control, data acquisition, and data analysis.
Twenty-three of the 25 UNIX systems are used mostly for theoretical and
graphical activities. The other two are used to control data acquisition
systems. The personal computers are used for word processing, spreadsheets,
data bases, graphics, computations, experiment control, data acquisition,
and data analysis.
In addition to the central computers, the Computer Services Group manages
several RISC-ased computers. These IBM RS/6000 and DEC AXP RISC systems
have proven to be reliable, cost-effective computers. Twelve DEC RISC
computers, with the power of 3000 MicroVAX II systems, perform parallel
computing.
To satisfy its more intensive computational needs, the Chemistry Division
has access to an onsite IBM/SPn parallel computer facility. The IBM/SPn
facility is one of the largest computers in the world, with 128 IBM 370
RISC stations tightly coupled together for an aggregate CPO rating of
16 GFLOPS and an aggregate memory of 16 GB (in 1994). In addition, the
Chemical Physics program has an 8-node satellite cluster connected to
the larger machine. A multiyear schedule of upgrades will dramatically
increase the aggregate power of this facility.
