Design, Design Communication, and Documentation
  • Use of synchronization constructs demonstrates an understanding of their intended purpose and use.
  • No race conditions or concurrency errors revealed when visually inspected.
  • Parallelism is not unnecessarily limited.
  • Data structures are always created and managed correctly and efficiently.
  • Scheduler is not invoked unnecessarily.
  • In alarm, design ensures that threads will wake on time.
  • Priority scheduling and priority donation are properly designed in all cases.
  • Design document accurately and clearly describes code function and answers the given questions clearly and succinctly.
  • Follows all structure and formatting guidelines, including those provided for the design document.
  • Use of synchronization constructs demonstrates a satisfactory understanding of their intended purpose and use.
  • When visually inspected, reveals two or fewer race conditions or concurrency errors
  • Parallelism is sometimes unnecessarily limited.
  • Data structures are sometimes not created and managed correctly and efficiently.
  • Scheduler is sometimes invoked unnecessarily.
  • In alarm, design may cause thread waking to be minimally early or late, even if not caught in test cases.
  • Priority scheduling and priority donation are properly designed in most cases, but in some instances the wrong thread may be scheduled.
  • Design document satisfactorily describes code function and answers the given questions clearly and succinctly.
  • Follows most structure and formatting guidelines, including those provided for the design document.
  • Use of synchronization constructs demonstrates an unsatisfactory understanding of their intended purpose and use.
  • When visually inspected, reveals five or fewer race conditions or concurrency errors
  • Parallelism is often unnecessarily limited.
  • Data structures are often not created and managed correctly and efficiently.
  • Scheduler is often invoked unnecessarily.
  • In alarm, design may cause thread waking to be early or late, even if not caught in test cases.
  • Priority scheduling and priority donation are properly designed in some cases, but often the wrong thread may be scheduled.
  • Design document unsatisfactorily describes code function and answers the given questions clearly and succinctly.
  • Follows few structure and formatting guidelines, including those provided for the design document.
  • Use of synchronization constructs reveals a lack of understanding of their intended purpose and use.
  • When visually inspected, reveals many race conditions, concurrency errors, or a failure to use synchronization at all.
  • Parallelism is unnecessarily limited.
  • Data structures are not created and managed correctly and efficiently.
  • Scheduler is regularly invoked unnecessarily.
  • In alarm, design may cause some threads to never wake up or never sleep, even if not caught in test cases.
  • Priority scheduling and priority donation are not properly designed in most or all cases, and the wrong thread is usually scheduled.
  • Design document incorrectly or fails to describe code function and answer the given questions clearly and succinctly.
  • Follows few structure and formatting guidelines, including those provided for the design document.
Test Cases
  • Code submission passes all test cases
  • Code submission passes 15 test cases or more
  • Code submission passes 10 test cases or more
  • Code submission fails more than 10 test cases or doesn't execute
Notes
  • Completing the a) planning and reflections and b) evaluation documents for this project will add 4/10ths to your design score, or the pro-rated equivalent. However, a grade higher than a 5 may not be awarded. Conversely, students who fail to complete all documents may earn a maximum of a 4 on the design
  • Turning in the skeleton code earns a design document score of 1.
  • Be certain to review the General Grading Criteria that applies to all projects.
  • You may report a grade discrepancy if you feel that we overlooked information and thus made a mistake in evaluating your submission. Please see the syllabus for more information.
