Example 1 with THashSet

use of gnu.trove.set.hash.THashSet in project scheduler by btrplace.

the class FixedNodeSetsPartitioning method split.

@Override
public List<Instance> split(Parameters ps, Instance i) throws SchedulerException {
    Model mo = i.getModel();
    SynchronizedElementBuilder eb = new SynchronizedElementBuilder(mo);
    List<Instance> parts = new ArrayList<>(partitions.size());

    int partNumber = 0;
    Set<VM> toLaunch = getVMsToLaunch(i);
    for (Collection<Node> s : partitions) {
        SubModel partModel = new SubModel(mo, eb, s, new HashSet<>(toLaunch.size() / partitions.size()));
        parts.add(new Instance(partModel, new THashSet<>(), i.getOptConstraint()));

    int p = 0;

        if (!parts.get(p).getModel().getMapping().addReadyVM(v)) {
            throw new SplitException(parts.get(p).getModel(), "Unable to dispatch the VM to launch '" + v + "'");
        }
        vmPosition.put(v.id(), p);

Example 2 with THashSet

use of gnu.trove.set.hash.THashSet in project scheduler by btrplace.

    Mapping m = i.getModel().getMapping();
    Set<VM> toLaunch = new THashSet<>();
    for (SatConstraint cstr : i.getSatConstraints()) {
