Example 1 with InterestingPoint

use of org.apache.sysml.hops.codegen.opt.InterestingPoint in project incubator-systemml by apache.

the class CPlanMemoTable method pruneRedundant.

    if (!contains(hopID))
        return;
    // prune redundant plans (i.e., equivalent)
    setDistinct(hopID, _plans.get(hopID));
    // prune closed templates without group references
    _plans.get(hopID).removeIf(p -> p.isClosed() && !p.hasPlanRef());
    // heuristic that only consider materialization points)
