218 * Documentation? You want DOCUMENTATION?
219 *
220 * Why all the potatoes below?
221 *
222 * To make a long story short, the original version of DumpWriter
223 * worked in the most inefficient way possible. Node 0 would
224 * poke each of the node for an individual atom's formatted data
225 * as node 0 worked its way down the global index. This was particularly
226 * inefficient since the method blocked all processors at every atom
227 * (and did it twice!).
228 *
229 * An intermediate version of DumpWriter could be described from Node
230 * zero's perspective as follows:
231 *
232 * 1) Have 100 of your friends stand in a circle.
233 * 2) When you say go, have all of them start tossing potatoes at
234 * you (one at a time).
235 * 3) Catch the potatoes.
236 *
237 * It was an improvement, but MPI has buffers and caches that could
238 * best be described in this analogy as "potato nets", so there's no
239 * need to block the processors atom-by-atom.
240 *
241 * This new and improved DumpWriter works in an even more efficient
242 * way:
243 *
244 * 1) Have 100 of your friend stand in a circle.
245 * 2) When you say go, have them start tossing 5-pound bags of
246 * potatoes at you.
247 * 3) Once you've caught a friend's bag of potatoes,
248 * toss them a spud to let them know they can toss another bag.
249 *
250 * How's THAT for documentation?
