CUMULVS was funded by the U.S. Department of Energy.
CUMULVS is an infrastructure library that allows a programmer to
easily extract data from a running parallel simulation and send the
data to a visualization package. CUMULVS includes the capability to
steer user-defined parameters in a distributed simulation. A future
feature being added to CUMULVS is the ability to perform user-directed
checkpointing and restarts of parallel programs across a heterogeneous
network. The interface is kept as simple as possible. The programmer
merely defines the decomposition of parallel data and the number and
types of scalar parameters, and CUMULVS does the rest. It supports
the simultaneous viewing of multiple dynamically attached front-end
visualization programs, or viewers. A single interface routine
handles the attachment / detachment protocols, the selection and
sending of data, and updating steering parameters. CUMULVS allows
each viewer to interactively select the granularity and extent of
data that it desires to see. This allows the user to effectively
visualize large datasets without exhausting the available network
bandwidth. The next release of CUMULVS will also support user-
directed checkpointing and restarts across a heterogeneous machine.
The visualization and checkpointing features of CUMULVS will be
independent.
