Presentation Transcript

  1. Parallel Systems Guy Tel-Zur Lecture 8

  2. Agenda • Parallel Programming in Shared Memory - 1. Introduction2. OpenMP • SC12 presentation • Students’ Presentations

  3. Latency Factors in Data Center Reference: Intel's 10 Gigabit Ethernet boost pushes out Infiniband

  4. Comments about the final presentations • Pay attention to: • Parallel Computing aspects. For example: speedup, efficiency, scalability, computation to communication ratio, how close your program to Amdahl’s law prediction?, run time vs. problem size. • See more instructions in Lecture #1 slides • Please hurry! The time is running fast now….

  5. OpenMPfrom Wikipedia מומלץ להסתכל בסימוכין הנוספים באתר הויקיפדיה!

  6. Relevant slides in “SC99 tutorial” Pages: 1-64, 109, 112-116,140-149, 143

  7. Q&A שלום גיא  .לא ברור לי למה אבל המחשב נתקע לי בכל פעם שאני מריץ איתחול על מטריצה ,ממימד 100*100 ומעלה. האם זה סביר? יש פתרון לכך ? Open DevC++ demos: m_size.c and m_size2.c
