c++ - Parallelizing loops containing function call -

Is this function equally suitable for call loops, or is it a more convenient circulation of loop which is the original Operation

For example, does it keep the equation instructions as below?

  main () {.. #omp for paralel .. (i = 0; i & lt; 100; i ++) {a [i] = foo (and datatype,. ..); ...} ..} int foo (datatype * A, ...) {// complex operating is doing here // call other functions etc.}}

Thanks, Will Richard and Fakler, these comments were helpful and I had suggested the book RCHHD that there would be a deeper look. But before the end of the day, I want to make the current C code (actually a big loop that resides on top of the program), if possible, be parallel with OpenMP.

At this point, I need to help to make at least some parts of the loop parallel to some things, rather than to completely subdue the piral material, to simplify things, I How can I create a part

 for  (i) n () (work1 () - (serial) work2 () - (serial) work3 () - (PARALLEL) work 4 () - (Serial)} // Does this work (3 to 0) work for private (PTR) except for # 3, except AMP P parallel Gone is to be added. Single {work1 () - (serial) work2 () - (serial)} work3 (ptr) - (baral) #omp single {work4 () - (serial)}}   

Three bit notifications must be known:

1. Keeps in mind, are you executing Fu?
2. Does Fu () affect the shared portion, and is such a locking?
3. Open without any How long does the loop take to run an MF?

Near work that takes long - many seconds or more - and it can be divided into independent parts (sometimes by refactoring, for example, by dividing the jobs and

the profile!

Incidentally, the results of each job)
