An outline of computing and data acquisition support at JRM & KSU.
As evidenced by the existence of this Web document, computing is of
ever-growing importance to our scientific community.
There are three families of computers available to users of the
James R. Macdonald Laboratory:
- We use a
Linux-based multi-parameter data acquisition
system for our more complex experiments. There are now several data acquisition workstations. These
workstations connect to VME frontends, and via gigabit Ethernet to the central
Storage Area Network System
(SANs), which provides safe, massive data storage.
We also have remotely accessible Linux servers for offline data analysis.
Scientific high-performance computing is provided by a network of
Scientific Linux clusters and workstations.
A wide variety of computing tools are provided by this system, along with access
to other KSU
and to the Internet.
Finally, hordes of PC microcomputers are available for process control,
data reduction and presentation graphics work.
These PCs are part of a
Windows network domain that provides system flexibility and ease of maintenance. All basic services of our network are now provided by clustered servers
running Windows Server. The Physics domain is administered by the Physics Computing Support Center
Many of these PCs have speciality software programmed in
LabView graphical programming language. Rapid development and near-universal vendor support makes LabView an attractive option.
Users new to the system should consult the
New User's Guide for helpful hints and important
All of these machine families are extensively networked together to
provide easy transfer of data and maintain maximum user productivity
and happiness. A campus-wide
is available, as is a dedicated wireless network with the JRM lab.
