OK, I've run trinity for one known bug in 2.6 in perf_event_open it it seems to me that reproduciblity is not an issue for one child process. They both runs start in sync and end in sycn precisely. But apparently more than one child causes all child to go out of sync from the beginning, i.e., even the very first call in each child is called with different parameters. Will look into it during the next week. -Ildar -- To unsubscribe from this list: send the line "unsubscribe trinity" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
