Memory/Ownership Notes

• Array, Map, Queue all steal ownership of what's passed into them

• Test files without memory leaks:

  • array, queue, map
  • serialization
  • message, cache, blocks, distributed array
  • schema
  • store, storeIntegration
  • trivial test (all 4 trials)
  • demo test
  • Sorer
  • Linus

• Tests with memory leaks/unchecked

  • Wordcount (1 leak - 10 bytes)

ReceiverThread Info

Receives WaitAndGet message it can't currently respond to -> add to KVStore's msgsCache_ (map). When new data is added to a KVStore (RT calls kv_->put()), KVStore adds it locally, then checks the msgCache_ map to see if anyone else was looking for the data that just came in. It sends the responses if available

Additional notes

• Don't use args unless it's specifically for network; pseudo doesn't use all of them
• Key stored for each block (DF is DataFrame's key): Key('DF-colIdx-blockIdx', blockIdx % numNodes)
• Real Network sends a Message as the serialized msg type prepended to the serialized message.

Notes for things to improve from before:
