* global scheduler with object transfer cost awareness -- upstream rebase * debugging global scheduler: multiple subscriptions * global scheduler: utarray push bug fix; tasks change state to SCHEDULED * change global scheduler test to be an integraton test * unit and integration tests are passing for global scheduler * improve global scheduler test: break up into several * global scheduler checkpoint: fix photon object id bug in test * test with timesync between object and task notifications; TODO: handle OoO object+task notifications in GS * fallback to base policy if no object dependencies are cached (may happen due to OoO object+task notification arrivals * clean up printfs; handle a missing LS in LS cache * Minor changes to Python test and factor out some common code. * refactoring handle task waiting * addressing comments * log_info -> log_debug * Change object ID printing. * PRId64 merge * Python 3 fix. * PRId64. * Python 3 fix. * resurrect differentiation between no args and missing object info; spacing * Valgrind fix. * Run all global scheduler tests in valgrind. * clang format * Comments and documentation changes. * Minor cleanups. * fix whitespace * Fix. * Documentation fix.
