We are reading the list, but not every day. Fortunately, I have colleagues. ;) As to Olga's question: It does nearly the same as Dist.makeBlock. http://x10.sourceforge.net/x10doc/2.2.3/x10/array/Dist.html#makeBlock(x10.array.Region,x10.lang.Int) The difference is that it not necessarily divides evenly among places, but rather takes into account how many PEs are on each place. So places with more parallelism get more work to do. More precisely, it returns a PEBlockDist object, which is a BlockDist with some additional methods like blockRegionForPE.
