  Applied rule-based rewrites
  - 1) rewrite set data partitioner (incl. recompile RIX)
  - 2) rewrite remove unnecessary compare matrix
  - 3) rewrite result partitioning (incl. recompile LIX)
  - 4) rewrite set execution strategy
  - 5) rewrite set operations exec type (incl. recompile)
  - 6) rewrite use data colocation
  - 7) rewrite set partition replication factor
  - 8) rewrite set export replication factor
  - 9) rewrite use nested parallelism
  - 10) rewrite set degree of parallelism
  - 11) rewrite set task partitioner
  - 12) rewrite set fused data partitioning and execution
  - 13) rewrite transpose vector operations (for sparse)
  - 14) rewrite set in-place result indexing
  - 15) rewrite disable caching (prevent sparse serialization)
  - 16) rewrite enable runtime piggybacking
  - 17) rewrite inject spark loop checkpointing
  - 18) rewrite inject spark repartition (for zipmm)
  - 19) rewrite set spark eager rdd caching
  - 20) rewrite set result merge
  - 21) rewrite set recompile memory budget
  - 22) rewrite remove recursive parfor
  - 23) rewrite remove unnecessary parfor

  TODO fuse also result merge into fused data partitioning and execute
       (for writing the result directly from execute we need to partition
       columns/rows according to blocksize -&gt; rewrite (only applicable if
       numCols/blocksize&gt;numreducers)+custom MR partitioner)

 <div class="block">This dedicated execution mode can only be applied if all of the
  following conditions are true:
  - Only cp instructions in the parfor body
  - Only one partitioned input
  - number of iterations is equal to number of partitions (nrow/ncol)
  - partitioned matrix access via plain iteration variables (no composed expressions)
    (this ensures that each partition is exactly read once)
  - no left indexing (since by default static task partitioning)

  Furthermore, it should be only chosen if we already decided for remote partitioning
  and otherwise would create a large number of partition files.

  NOTE: We already respect the reducer memory budget for plan correctness. However,
  we miss optimization potential if the reducer budget is larger than the mapper budget
  (if we were not able to select REMOTE_MR as execution strategy wrt mapper budget)
