The Logistical Computing and Internetworking (LoCI)
Laboratory, headed by Drs. Micah Beck and James S. Plank of the
Computer Science Department of the University of Tennessee, is devoted
to information logistics in distributed computer systems and networks.
Information logistics is the study of the flexible coscheduling of the
fundamental physical resources that underpin computer systems: storage,
computation, and data transmission.
(NEW!)You are invited to try
our new featured service, the Logistical Distribution Network (LoDN), which is an experimental content
distribution tool. LoDN allows users to store content on the Logistical
Network, and manage or retrieve that stored content. In order to use
LoDN, all you need is a standard web browser, a recent Java runtime
environment and an access to the world wide web. Click here for
more information about LoDN and Logistical Networking.
LoRS v 0.82.2 [tar.bz2] (13.6 MB)
This is the lastest LoRS code.
IBP v 18.104.22.168 [tar.gz] (1.3MB)
This is the latest IBP code. It includes fixes for several compilation and configuration bugs in the 22.214.171.124 package.
LoRS Visual Tools
for Win32 v0.82 [.zip] (11MB)
This package combines the LoRS CLI with the visual front end and uses a
self-extracting installation. This package depends upon both the
ActiveState Tcl/TK distribution and the ActiveState Perl package. The
setup.exe will test for their presence and download them if needed.
Installation instructions are available here.
LoRS Visual Tools
v0.82.1 for MacOSX [.dmg] (5.0 MB)
This disk image (5.0 MB) contains
LorsCommand which combines LoRS CLI v 0.82 and LoRS View v 0.82 in a
single, drag-and-drop application (no Developer Tools required).
LorsCommand requires the TclTkAquaBI package of Tcl/Tk for Aqua

Manual v0.82 [.pdf] (1MB)
This manual guides a user through the installation and configuration
process for Unix, Mac OS X, and Windows. The manual also covers all
major operations of the GUI interface with an appendix for the command

Library of Congress Supports IBP
The LoCI team was recently invited to the National Digital Information
Infrastructure Preservation Program (NDIIPP) meeting in Arlington, Virginia
headed by the Library of Congress. The NDIIPP was founded by Congress in 2000
in order to archive and preserve digital content.
LoCI screencasts are now avaiable. You can use the link in the left-hand
navigation bar or click here. These informative
screencasts will teach a newcomer how to use some of our tools and services
while providing a brief overview of LoDN and how it functions. Special thanks
to Harold Gonzales and Dr. Terry Moore for providing these videos.
The NetCDF/L 3.5.2 is
NetCDF/L 3.5.2 has now been released and is available for download
link. Compared to NetCDF/L 3.5.1, several bugs have been fixed in
this 3.5.2 version. We will continue to work on NetCDF/L 3.6.0, which
will provide large file support. The Network Common Data Form, or
netCDF, is an interface to a library of data access functions for
storing and retrieving data in the form of arrays. Developed by Unidata,
it is an abstraction that supports a view of data as a collection of
self-describing, portable objects that can be accessed through a simple
interface. Based on the netcdf-3.5.1 software package, LoCI Lab has
developed NetCDF/L software package which adds Logistical Networking
capabilities. Like traditional NetCDF it can store data on local disk
and it can also store data on the global logistical network.
