* Documentation? You want DOCUMENTATION? |

200 |
* Why all the potatoes below? |
201 |
* |
202 |
* To make a long story short, the original version of DumpWriter |
203 |
* worked in the most inefficient way possible. Node 0 would |
204 |
* poke each of the node for an individual atom's formatted data |
205 |
* as node 0 worked its way down the global index. This was particularly |
206 |
* inefficient since the method blocked all processors at every atom |
207 |
* (and did it twice!). |
208 |
* |
209 |
* An intermediate version of DumpWriter could be described from Node |
210 |
* zero's perspective as follows: |
211 |
* |
212 |
* 1) Have 100 of your friends stand in a circle. |
213 |
* 2) When you say go, have all of them start tossing potatoes at |
214 |
* you (one at a time). |
215 |
* 3) Catch the potatoes. |
216 |
* |
217 |
* It was an improvement, but MPI has buffers and caches that could |
218 |
* best be described in this analogy as "potato nets", so there's no |
219 |
* need to block the processors atom-by-atom. |
220 |
* |
221 |
* This new and improved DumpWriter works in an even more efficient |
222 |
* way: |
223 |
* |
224 |
* 1) Have 100 of your friend stand in a circle. |
225 |
* 2) When you say go, have them start tossing 5-pound bags of |
226 |
* potatoes at you. |
227 |
* 3) Once you've caught a friend's bag of potatoes, |
228 |
* toss them a spud to let them know they can toss another bag. |
229 |
* |
230 |
* How's THAT for documentation? |
