Hi everyone, Do any of you now, or have you in the past, used the 'source' keyword as supplied to creation of a slice? I have successfully finished the parallelization of both cutting planes and slices, but to do the slices I had to (or chose to, really) move from a 2d domain decomp to a standard grid iterator; this means I got rid of source=. For 2.0, all the data objects will implement the correct protocol, so source will come back, but for 1.5 I'd like to put out a working parallel slice & cutting plane pair. But, I don't want to cut off anybody's legs. Thanks! -Matt
