The UTHSCSA Center for Biomolecular NMR supports an extensive
network of offline computer workstations and associated software to facilitate
in the offline analysis of NMR data collected in the Center. This
computer system is presently Linux-based and includes a cluster of six
windows Linux workstations. Although each of the computers differs
slightly from the others with respect to their CPU, memory, and data storage,
a uniform computing environment is maintained
by using two well-established Linux networking protocols - network information
services (NIS) and network file system (NFS).
NIS is important in this regard as this provides a server
- client type of model wherein basic administration tasks, such as maintenance
of user accounts and file permissions, are accomplished system-wide through
the computer designated as the "NIS server". NFS provides additional
important capability in this regard as it provides a means data disk sharing
among computers which are part of the NIS network. The combined
advantage of this type of computing environment is that user accounts,
software packages, and data disks which are available for reading/writing
are identical irregardless of which workstation is utilized for processing.
These features are important for ensuring effective use of the computing
resources available in the Center since in effect users are only required
to be familiar with a single type of computer system, even though the computer
system itself is comprised of multiple non-identical hardware components.
The approach also offers numerous obvious advantages to the adminstrator,
but probably the most important of these is flexibility with regard to
upgrading hardware or software components of the system.
These web pages are an integral part of the Biomolecular
NMR NIS computer system. They provide information about the computing
resources available (and how to use them), as well as which software packages
are available (and how to use them). In many cases, online manuals
are available. In other cases (particularly for some of the customized
software packages and utilities that have been developed by staff in the
NMR facility) only a brief description of the how to run the program is
provided. Access to the Biomolecular NMR NIS computer system
is provided free of charge to any UTHSCSA faculty or staff who is accessing
the facility. If you would like to request access, please send an
email message to the facility director.
