* Documentation? You want DOCUMENTATION? |
310 |
* |
311 |
* Why all the potatoes below? |
312 |
* |
313 |
* To make a long story short, the original version of DumpWriter |
314 |
* worked in the most inefficient way possible. Node 0 would |
315 |
* poke each of the node for an individual atom's formatted data |
316 |
* as node 0 worked its way down the global index. This was particularly |
317 |
* inefficient since the method blocked all processors at every atom |
318 |
* (and did it twice!). |
319 |
* |
320 |
* An intermediate version of DumpWriter could be described from Node |
321 |
* zero's perspective as follows: |
322 |
* |
323 |
* 1) Have 100 of your friends stand in a circle. |
324 |
* 2) When you say go, have all of them start tossing potatoes at |
325 |
* you (one at a time). |
326 |
* 3) Catch the potatoes. |
327 |
* |
328 |
* It was an improvement, but MPI has buffers and caches that could |
329 |
* best be described in this analogy as "potato nets", so there's no |
330 |
* need to block the processors atom-by-atom. |
331 |
* |
332 |
* This new and improved DumpWriter works in an even more efficient |
333 |
* way: |
334 |
* |
335 |
* 1) Have 100 of your friend stand in a circle. |
336 |
* 2) When you say go, have them start tossing 5-pound bags of |
337 |
* potatoes at you. |
338 |
* 3) Once you've caught a friend's bag of potatoes, |
339 |
* toss them a spud to let them know they can toss another bag. |
340 |
* |
341 |
* How's THAT for documentation? |
