InSituModule
acquire data from SENSEI or Catalyst II instrumented simulations
Purpose
This module is used to connect to a simulation via the Catalyst II or SENSEI in-situ interface.
Ports
Output ports are created dynamically, based on information from the coupling definition and simulation.
Parameters
name |
description |
type |
|---|---|---|
path |
path to the connection file written by the simulation |
String |
frequency |
the pipeline is processed for every nth simulation cycle |
Int |
keep_timesteps |
if true timesteps are cached and processed as time series |
Int |
Set the path parameter to a connection file written by the simulation. The default value should be sufficient.
The value of frequency determines how often the pipeline is processed. If set to 1, the pipeline is processed every cycle. Setting it to a value of n will skip n-1 cycles and process the pipeline every nth cycle.
The keep_timesteps flag controls whether the data from all timesteps is retained for rendering or if only the current/newest timestep can be displayed.
FIXME -simulation specific commands: if we are connected, the simulation sets commands that will be send to the simulation when the status of the according parameter is changed (value does not matter).
Communication details
-command shm-message-queue: exchange information between SENSEI’s Vistle-analysis-adapter and the module -recvFromSim shm-message-queue: we receive vistle messages from the simulation and pass them to the manager as if the came from this module. Mainly used to add vistle objects to the pipeline.
