Multi-level Visualization of Concurrent and Distributed Computation in Erlang

This paper describes a prototype visualization system

using Erlang, providing two levels of granularity of view. Both

the computation.

At the low level, we show the concurrent behaviour of the

machine, which we call an Erlang node. Typically there will be

maintains a run queue of processes to execute, and we visualize

to another as work is redistributed to fully exploit the hardware.

to each scheduler we draw a variable length bar indicating the

system, showing interactions between Erlang nodes as a dynamic

passing between nodes as edges and lay out nodes according to

of nodes into “s_groups” using an Euler diagram drawn with

circles.
