00:00:03.785 --> 00:00:04.998
2
00:00:04.999 --> 00:00:18.129
[Theme song from Rawhide]
3
00:00:18.130 --> 00:00:26.345
4
00:00:26.345 --> 00:00:29.278
NC State is an AG school, and North Carolinians
5
00:00:29.279 --> 00:00:32.948
like to support their local farms.
6
00:00:32.948 --> 00:00:37.361
NC State is also home to your favorite Advanced Computing Specialist,
7
00:00:37.361 --> 00:00:40.724
and she supports the high-performance computing center.
8
00:00:40.725 --> 00:00:45.702
In this project, she supports the hydrodynamics modeling for Mobile Bay.
9
00:00:45.703 --> 00:00:51.066
10
00:00:51.066 --> 00:00:53.657
Raising a cow takes a lot of time and effort.
11
00:00:53.657 --> 00:00:56.913
It is expensive. And it takes a lot of space.
12
00:00:56.914 --> 00:00:58.026
13
00:00:58.026 --> 00:01:03.666
Our hydrodynamics model can take several weeks to run - even on a supercomputer!
14
00:01:03.666 --> 00:01:06.053
Processing the resulting output
15
00:01:06.054 --> 00:01:08.129
can take several months.
16
00:01:08.129 --> 00:01:09.185
17
00:01:09.185 --> 00:01:13.417
The model generates 6TB of data.
18
00:01:13.417 --> 00:01:17.262
in other words, our data is a cow.
19
00:01:17.263 --> 00:01:19.311
20
00:01:19.312 --> 00:01:25.206
21
00:01:25.206 --> 00:01:28.136
A small farm can't afford to make any mistakes.
22
00:01:28.136 --> 00:01:30.418
Before they start raising the first cow,
23
00:01:30.419 --> 00:01:33.031
they need to know who their consumers will be.
24
00:01:33.031 --> 00:01:34.800
Which products will they want?
25
00:01:34.801 --> 00:01:38.526
And how do they need the products to be packaged?
26
00:01:38.526 --> 00:01:42.846
Likewise, before generating the next six terabytes of data,
27
00:01:42.846 --> 00:01:45.606
we need to know who the consumers will be.
28
00:01:45.606 --> 00:01:47.886
Which products do they want?
29
00:01:47.886 --> 00:01:51.838
And how do they need the products to be packaged?
30
00:01:56.766 --> 00:01:58.926
To get the cow ready for market,
31
00:01:58.926 --> 00:02:01.026
the processing must be done in a plant.
32
00:02:01.026 --> 00:02:03.606
This job is only done once.
33
00:02:03.606 --> 00:02:06.246
The cow goes in...
34
00:02:06.246 --> 00:02:09.806
and the products go out.
35
00:02:09.807 --> 00:02:12.185
36
00:02:12.185 --> 00:02:16.443
The data for our model needs to be processed on the supercomputer.
37
00:02:16.444 --> 00:02:20.165
Hopefully, this job is only done once.
38
00:02:20.165 --> 00:02:23.362
Ideally, the processing is done immediately.
39
00:02:23.363 --> 00:02:26.106
When the job finishes!
40
00:02:26.106 --> 00:02:29.586
41
00:02:29.586 --> 00:02:32.638
The data needs to be processed on the supercomputer.
42
00:02:32.639 --> 00:02:36.726
But we can't store it there. It will need to be archived.
43
00:02:36.726 --> 00:02:39.256
And we can't process data in that type of storage.
44
00:02:39.257 --> 00:02:42.426
If we don't have a list of the products needed when a model is finished,
45
00:02:42.426 --> 00:02:46.238
we end up moving the data back and forth.
46
00:02:46.239 --> 00:02:58.506
47
00:02:58.506 --> 00:03:02.607
We take great care to create models that get the science right.
48
00:03:02.607 --> 00:03:06.005
And to get things right, sometimes you need a cow.
49
00:03:06.006 --> 00:03:08.287
We do need to pause, to think,
50
00:03:08.287 --> 00:03:11.465
and to make some data management decisions.
51
00:03:11.466 --> 00:03:12.786
Preferably...
52
00:03:12.786 --> 00:03:15.925
as soon as possible!
