Look at the latest update OK, I thought I had but I didn't notice wget saving the file as cc.zip.1 rather than overwriting the version I downloaded earlier in the week. Anyway I ran ran the code built with Sun Studio rather than gcc because it runs quite a bit faster. As I expected, the big difference was in sorting: ccl version: To sort 85.6384S C++ version (std::list.sort()): To sort 18.7927S Iteration was closer: To access 2.80655S (ccl) To access 1.82896S -- Ian Collins
