What does it mean when with mmap I am getting "Each node loaded 1/8 of wordfile to memory (about 15 MB/node)"? Doesn't mmap imply that each node has the full wordlist mapped into its address space? In fact, without mmap I am getting "Each node loaded the whole wordfile to memory". Doesn't not using mmap enable easy and efficient loading of portions of the wordlist into each node's memory? This looks backwards to me. Can you explain? Alexander
