- In the majority of Fortran V implementations, all parameters were supplied by reference, with just the access path transmission being used. In your own words, describe both the pros and cons of this design decision.arrow_forwardThis is some code in C for quicksort. The quicksort works correctly, but I am trying to implement multithreading. I am trying to run the recursive calls in parallel with a limit on how much threads can be running at one time (set by the global variable 'maximumThreads'). My logic is incorrect with managing how many threads can be ran at the same time. The part that I need you to look at is after the for loop in quick sort, where I have my logic for the mutex and the conditional variable. Right now when I run my code, the program runs without stopping. I would like help with correctly implementing this. #include <stdlib.h>#include <string.h>#include <pthread.h>#include <stdio.h>#define SORT_THRESHOLD 40typedef struct _sortParams {char** array;int left;int right;int* currentThreads;pthread_mutex_t* mutex;pthread_cond_t* cond_var} SortParams;static int maximumThreads; /* maximum # of threads to be used *//* This is an implementation of insert sort, which although…arrow_forwardHow do the benefits and drawbacks of Java's implicit heap storage recovery stack up against C++'s need for explicit heap storage recovery? Consider, as an example, the case of real-time systems.arrow_forward
- All parameters in most Fortran IV implementations were reference-supplied, and only the access path transmission was really utilized. Discuss the benefits and drawbacks of this design choice in your own words.arrow_forwardPlease use C++ to code a multi-threaded sieve of Eratosthenes program using MPIarrow_forwardExplain why it is easier to share a reentrant module using segmentation than it is to do so when pure paging is used.arrow_forward
- In your opinion, for what kind of program would the layered architecture approach work best?arrow_forwardIn this lab, we write function binary_search in RISC-V. The prototype of the function and an implementation in C is at the end of this page. Translate the C code at the bottom of the page to RISC-V assembly code. The skeleton code is in lab4.s. Function binary_search is located at the end of the file. It is empty in the skeleton code. There are some constraints/tips. 1. To ensure we do not use pseudoinstructions, we turn off the feature in RARs. In Settings, uncheck "Permit extended (pseudo) instructions and formats". 2. Follow the C code closely. Although binary search is simple, it is very easy to make mistakes if you have not written it many times. 3. We keep variable left in register s1. Other local variables do not have to be in a saved register. Think about why we need to keep left, but not other variables, in a saved register. 4. There should be only one exit (one return instruction) in the function. In the C code, we use goto f_exit on purpose. With one exit, we do not have…arrow_forwardA Program to Test the CSet Implementation in c#arrow_forward
