Textbook Question
Chapter 5, Problem 5.15HW
Write a version of the inner product procedure described in Problem 5.13 that uses 6 × 6 loop unrolling. Our measurements for this function with x86-64 give a CPE of 1.06 for integer data and 1.01 for floating-point data.
What factor limits the performance to a CPE of 1.00?

Show examples of C code that explicitly do a read-modify-write operation on SAMD21 I/O pin PA02 to setthis bit in a PORT register, clear it in a PORT register, and toggle it in a PORT register. You may assumeit has already been initialized as an output. If possible, show an example of code that implicitlydoes a read-modify-write operation on this pin.
Write a program in MIPS assembly that allows replacing a substring with another substring. Use any function and variable of your choice.
For example:
Input:
- Initial text: XXabXXcd
- Word to replace : XX
- Replacement word: YY
Output: YYabYYcd

- Implement a shared-memory pthread program on in C to find Prefix Sum of n integers. Keep theparallel overheads to a minimum. (One barrier synchronization may be enough.) Vary n as 210, 215, and 220 (or moreif desired), and p, the number of processes, from 1 to 8, and obtain the speedup relative to the sequential timingswithout any overheads. Produce a speedup plot with p on x-axis and Sp on y-axis. Each n will result in a separatespeedup curve. Use same plot for all the curves to see how speedup varies as problem size increases.arrow_forwardConsider a program where 95% of the code can be parallelized.
