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 and memory accesses are always created and/or managed correctly and efficiently.
  • File system always efficiently stores and accesses files of various sizes, including small ones and those up to 8MB.
  • File system always correctly extends files and directories while providing for fairness between readers and writers.
  • File system correctly and efficiently implements directories and subdirectories, including in the case of file removal and tracking the current working directory.
  • Design document accurately and clearly describes code function and answers the given questions clearly and succinctly.
  • Code 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 and memory accesses are sometimes not created and/or managed correctly and efficiently.
  • File system often efficiently stores and accesses files of various sizes, including small ones and those up to 8MB.
  • File system often correctly extends files and directories while providing for fairness between readers and writers.
  • File system often correctly and efficiently implements directories and subdirectories, including in the case of file removal and tracking the current working directory.
  • Design document satisfactorily describes code function and answers the given questions clearly and succinctly.
  • Code 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 and memory accesses are often not created and/or managed correctly and efficiently.
  • File system sometimes efficiently stores and accesses files of various sizes, including small ones and those up to 8MB.
  • File system sometimes correctly extends files and directories while providing for fairness between readers and writers.
  • File system sometimes correctly and efficiently implements directories and subdirectories, including in the case of file removal and tracking the current working directory.
  • Design document unsatisfactorily describes code function and answers the given questions clearly and succinctly.
  • Code 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 and memory accesses are not created and/or managed correctly and efficiently.
  • File system does not efficiently store and access files of various sizes, including small ones and those up to 8MB.
  • File system incorrectly extends files and directories while not providing for fairness between readers and writers.
  • File system incorrectly implements directories and subdirectories, including in the case of file removal and tracking the current working directory.
  • Design document incorrectly or fails to describe code function and answer the given questions clearly and succinctly.
  • Code follows few structure and formatting guidelines, including those provided for the design document.
Test Cases
  • Code submission passes all of the test cases.
  • Code submission passes 115 or more of the test cases.
    Corresponds to missing a few cases, like dir-vine
  • Code submission passes 95 or more of the test cases.
    Roughly corresponds to file growth tests and marginally adding subdirectories.
  • Code submission passes less than 95 of the test cases or doesn't execute.
Notes
  • Completing the a) planning and reflections and b) evaluation documents for this project will add 6/10ths to your design score, or the pro-rated equivalent. However, a grade higher than a 5 may not be awarded. Conversely, students who do not complete all documents may earn a maximum of a 4 on the design.
  • Turning in the skeleton code or your Project 2 code base earns a maximum 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 note that the deadline for the submission of the form will be quick due to deadlines around final grade submission.
