The Problem:
The complex modeling and teraops level computing required to solve the
challenging problems of interest to DOE are not always readily accessible to
research scientists. Accessibility and usability are enhanced through the
development and use of enabling tools.
ORNL, a pioneer
in tools development, has staff with the varied
skills needed to meet these challenges. By removing distance as a barrier to collaboration (whether among people or among people
using remote instruments), we can shrink travel time and expense. We can also provide more
powerful simulation tools for problem solving than ever before by providing tools that
harness multiple, geographically separate high-performance computers.
ORNL Solutions:
- Electronic notebooks allow shared record keeping by collaborators regardless of their location.
- Software tools allow remote operation of research instruments.
- CUMULVS supports interactive visualization and remote computational steering of distributed applications by multiple collaborators, and provides a mechanism for constructing fault-tolerant, migrating applications in heterogeneous distributed computing environments.
- The Harness project will support heterogeneous distributed computing environments that can include everything from laptops running Windows 95/NT to multiprocessor supercomputers running Unix.
- Scalapack offers additional mathematical resources.
- NetSolve enables users to solve complex scientific problem remotely.
- ATLAS will provide automatic generation and optimization of numerical software for processors with deep memory hierarchies and pipelined functional units.

CUMULVS is a software infrastructure for the development of collaborative environments. It
supports interactive visualization and remote computational steering of distributed applications
by multiple collaborators, and provides a mechanism for constructing fault-tolerant, migrating
applications in heterogeneous distributed computing environments.

The Harness project
is developing key capabilities for
heterogeneous distributed computing environments
that can include everything from laptops running Windows 95/NT
to multiprocessor supercomputers running Unix. Harness builds on the concept of the Distributed Virtual Machine
that was pioneered by our PVM research, but fundamentally recreates
this idea and explores dynamic capabilities beyond what PVM can supply.

NetSolve is a client-server application that enables users to solve
complex scientific problem remotely. The system allows users to access
both hardware and software computational resources distributed across a
network. NetSolve searches for computational resources on a
network, chooses the best one available, and using retry for
fault-tolerance solves a problem, and returns the answers to the user.

ATLAS is an approach for
the automatic generation and optimization of numerical software for
processors with deep memory hierarchies and pipelined functional units.
The production of such software for machines ranging from desktop
workstations to embedded processors can be a tedious and time consuming
task. ATLAS has been designed to automate much of this process.
