|
* Documentation? You want DOCUMENTATION? |
| 180 |
|
|
* |
| 181 |
|
|
* Why all the potatoes below? |
| 182 |
|
|
* |
| 183 |
|
|
* To make a long story short, the original version of DumpWriter |
| 184 |
|
|
* worked in the most inefficient way possible. Node 0 would |
| 185 |
|
|
* poke each of the node for an individual atom's formatted data |
| 186 |
|
|
* as node 0 worked its way down the global index. This was particularly |
| 187 |
|
|
* inefficient since the method blocked all processors at every atom |
| 188 |
|
|
* (and did it twice!). |
| 189 |
|
|
* |
| 190 |
|
|
* An intermediate version of DumpWriter could be described from Node |
| 191 |
|
|
* zero's perspective as follows: |
| 192 |
|
|
* |
| 193 |
|
|
* 1) Have 100 of your friends stand in a circle. |
| 194 |
|
|
* 2) When you say go, have all of them start tossing potatoes at |
| 195 |
|
|
* you (one at a time). |
| 196 |
|
|
* 3) Catch the potatoes. |
| 197 |
|
|
* |
| 198 |
|
|
* It was an improvement, but MPI has buffers and caches that could |
| 199 |
|
|
* best be described in this analogy as "potato nets", so there's no |
| 200 |
|
|
* need to block the processors atom-by-atom. |
| 201 |
|
|
* |
| 202 |
|
|
* This new and improved DumpWriter works in an even more efficient |
| 203 |
|
|
* way: |
| 204 |
|
|
* |
| 205 |
|
|
* 1) Have 100 of your friend stand in a circle. |
| 206 |
|
|
* 2) When you say go, have them start tossing 5-pound bags of |
| 207 |
|
|
* potatoes at you. |
| 208 |
|
|
* 3) Once you've caught a friend's bag of potatoes, |
| 209 |
|
|
* toss them a spud to let them know they can toss another bag. |
| 210 |
|
|
* |
| 211 |
|
|
* How's THAT for documentation? |
