Openmp uses those bounds to divide work among different threads. There is no such thing possible with a while loop. Second, how do you expect your task to be parallelized? You are reading from a file, where probably sequential access is going to give you better performance than parallel access. WebAnother option you have is splitting the file, and processing those. Anyway, if the file is not too big, try reading it all and then processing it. If it's too big, try loading some records (Say, like two thousand lines) processing those in parallel, repeat. You may need to do some testing to see which approach suits you better. grad programs in psychology
