5.4.1.3 Generation for DLP

For DLP, the entire loop is copied to a new function. The data flow information in the loop header indicates which variables have to be communicated before and after the loop. As in TLP, variables are privatized in the function. An example of code generation for DLP is in Listing 5.5. Two new functions are created, one that spawns the threads and collects the results (dlp_f_spawn in Line 11) and a function that is used to implement the copies of the for loop (parLoop5 in Line 31). In the example, the loop is split into four copies.
