Example 5 with ICompute

use of edu.iu.dsc.tws.api.compute.nodes.ICompute in project twister2 by DSC-SPIDAL.

the class STAllGatherExample method buildTaskGraph.

@Override
public ComputeGraphBuilder buildTaskGraph() {
    List<Integer> taskStages = jobParameters.getTaskStages();
    int psource = taskStages.get(0);
    int psink = taskStages.get(1);
    MessageType dataType = MessageTypes.INTEGER_ARRAY;
    String edge = "edge";
    BaseSource g = new SourceTask(edge);
    ICompute r = new AllGatherSinkTask();
    computeGraphBuilder.addSource(SOURCE, g, psource);
    computeConnection = computeGraphBuilder.addCompute(SINK, r, psink);
    computeConnection.allgather(SOURCE).viaEdge(edge).withDataType(dataType);
    return computeGraphBuilder;
