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). |
