omp barrier Entry to and exit fromomp critical. Exit fromomp parallel. Exit fromomp for. Exit fromomp sections. Exit fromomp single. Theomp flushdirective must appear within a block or compound statement. For example: if (x!=0) { #pragma omp flush /* valid usage */ } ...
The OpenMP #pragma omp critical directive(__).A.behaves much like a mutex lockB.does not require programmers to identify critical sectionsC.does not guarantee prion of race conditionsD.is similar to functional languages的答案是什么.用刷刷题APP,拍照搜索答
其中omp是OpenMP的一个关键字.在制导指令名 directive_name后可以附加参数parameters(子句clauses)等 选项. #pragmaompdirective-name[clause,...]newline 制导指令前缀。对 所有的OpenMP语 句都需要这样的前 缀。 OpenMP制导指 令。在制导指令前 缀和子句之间必须 有一个正确的 OpenMP制导指 令。 子句。在没有...
