DescriptionThis short paper describes an experimental prototype of
in situ visualization in a task-based parallel
programming framework. A set of reusable visualization
tasks were composed with an existing simulation. The
visualization tasks include a local OpenGL renderer, a
parallel image compositor, and a display task. These
tasks were added to an existing fluid-particle-radiation
simulation, and weak scaling tests were run on up to 512
nodes of the Piz Daint supercomputer. Benchmarks showed
that the visualization components scaled and did not
reduce the simulation throughput. The compositor latency
increased logarithmically with increasing node
count.
