Moed B grades available | |
| ExamB grades are available via GR++. Your returned exam feedback will be available online soon, under the ExamB assignment. Appeals should be submitted until 20.3.2021 (Saturday) at 23:59 to the course website (electronically), available under the 'Assignments' tab. You do not need to attach the copy of your exam. "Oral" appeals or emails will not be considered. NOTE: Appeals MUST be submitted using the AppealsForm appearing in the AppealsB assignment - not using this form may cause your appeal to not be checked. The average of the exam grade (ExamB) is 66.57, and the average of the final grade (FinalB) is 72.07. The final grade was calculated as follows: FinalB = Round(0.65*ExamB+0.35*(HW1+HW2+HW3+HW4+HW5)/5) ----------------------------------- Informally, the only reason to submit an appeal is if you think that the checker was wrong or did not understand what you wrote. Note also that the grading is based on what was written in the exam and not on what you had in mind during the exam. |

הבהרות לגבי הקצאת חוצצים | |
| 1. כאשר מתבצעים קלט ופלט במקביל עם שני דיסקים, יש להקצות (בחוצצים כפולים) שני חוצצים לקלט ושניים לפלט. 2. אם אין צורך לכתוב את הפלט לדיסק, ניתן לוותר על חוצצי הפלט (כמו בשקף 8 בהרצאה על שאילתות). 3. כאשר החישוב נעשה כשלב מתוך חישוב שאילתה מורכבת, ההחלטה האם להקצות חוצצים לפלט, וכמה, תלויה בשלבי החישוב הבאים: בפרט, האם משתמשים ב-pipeline או כותבים תוצאות ביניים במקביל לחישוב. 4. בדוגמת המיון הפנימי אנו עובדים באיטרציות נפרדות: ממיינים את זיכרון העבודה ולא מתחילים את החישוב הבא עד שהוא יוצא כולו לפלט. כל חוצץ ממויין שיוצא לפלט יכול לשמש כחוצץ קלט בהכנה לאיטרציית המיון הבאה, ולכן אין צורך להקצות חוצצי קלט בנפרד (שימו לב, רק בדוגמאות משנים קודמות שבהן המיון הפנימי נעשה באלגוריתם R/S, שלא נלמד כיום, אכן היה צורך ב-4 חוצצים לקלט ולפלט). |
