sections

This question has previously been posted, like Alphabetical sections in table table view in swift , but I can't really wrap my head around it when I try to implement it into my own code. I have the standard functions to get the alphabetic sections in place: func numberOfSections(in tableView: UITableView) -> Int { return collation.sectionTitles.count } func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? { return collation.sectionTitles[section] } func sectionIndexTitles(for tableView: UITableView) -> [String]? { return collation.sectionIndexTitles } func

I wonder if there is any technique to create parallel sections in OpenMp using a for-loop. For example, instead of creating n different #pragma omp sections, I want to create them using an n-iteration for-loop with some changing parameters for each section. #pragma omp parallel sections { #pragma omp section { /* Executes in thread 1 */ } #pragma omp section { /* Executes in thread 2 */ } #pragma omp section { /* Executes in thread n */ } } Hristo Iliev With explicit OpenMP tasks: #pragma omp parallel { // Let only one thread create all tasks #pragma omp single nowait { for (int i = 0; i < num

I have seen an algorithm for parallel merge-sort in a this paper. This is the code: void mergesort_parallel_omp (int a[], int size, int temp[], int threads) { if ( threads == 1) { mergesort_serial(a, size, temp); } else if (threads > 1) { #pragma omp parallel sections { #pragma omp section mergesort_parallel_omp(a, size/2, temp, threads/2); #pragma omp section mergesort_parallel_omp(a + size/2, size - size/2, temp + size/2, threads - threads/2); } merge(a, size, temp); } // threads > 1 } I run it on a multicore. What happens is that at the leafs of the tree, 2 threads run in parallel. After

I have to create a table view (iPad app) that is able to show and collapse rows at different levels: - Client 1 - Category 1 - Info 1 - Info 2 - Category 2 - Info 1 - Info 2 - Category 3 - Info 1 - Info 2 - Client 2 - Category 1 - Info 1 - Info 2 and so on... If the user taps on a client row, the whole client related rows (Categories and infos under that client) should expand/collapse. In the other hand, if they tap on a particular Category only that category should expand/collapse. So i'm planning to have nested NSMutableDictionaries to hold data which i can access by dynamic keys (like
