PDF-Parallel programming 5 - 1 CHAPTER 5. LOOP-SPLITTING - NESTED LOOPS

Parallel programming 5 2 arallel Version 1 Our first parallel version simply splits the outer loop id processfork p for iid in iip y i 0 for j0 jn. Unlike sequential algorithms parallel algorithms cannot be analyzed very well in isolation One of our primary measures of goodness of a parallel system will be its scalability Scalability is the ability of a parallel system to take advantage of incr CS303E: Elements of Computers and Programming. Quote of the Day. Optimism is an occupational hazard of programming: testing is the treatment. . - K. Beck. . Logical Operators:. What are they?. Operators that act on . Chapter. 4. Repeated Tasks are for Computers. Think back to any very difficult quantitative problem that you had to solve in some science class. How long did it take?. How many times did you solve it?. Nested Quantifiers. Needed to express statements with multiple variables . Example 1. : “. x+y. = . y+x. for all real numbers” . . xy. (. x+y. = . y+x. ) . where the domains of . x. and .

We’ve seen many places where repetition is necessary in a problem.. We’ve been using the for loop for that purpose. For loops are called . definite. loops because we know how many times the loop needs to be executed. Eighth Edition. Chapter 5. Looping. Objectives. In this chapter, you will learn about:.

A loop is one of the most important structures in programming.. Describe for loops and their implementation in C . Describe their purpose. Specifically count-controlled loops. Count-controlled loops. We previous looked at executing a block of code a fixed number of times:. We’ve been using the for loop for that purpose. For loops are called . definite. loops because we know how many times the loop needs to be executed. There are situations where loops are needed but there is no way to determine ahead of time how many times they will run, this is an . Shamsa. Hassan . Alhassouni. For -G7. .
