Different configurations of the full setup, |

|
using cost = \sum_{i,j} theta(i,j)**2 |
| 4 |
|
|
They include: |
| 5 |
|
|
|
| 6 |
|
|
1. Single-processor: |
| 7 |
|
|
a. with hand-written AD routines |
| 8 |
|
|
* output_nompi_handad_adm.txt (FAIL) |
| 9 |
|
|
* output_nompi_handad_tlm.txt (OK) |
| 10 |
|
|
b. without hand-written AD routines for exch2_rx2_cube |
| 11 |
|
|
* output_nompi_nohandad_adm.txt (OK) |
| 12 |
|
|
* output_nompi_nohandad_tlm.txt (OK) |
| 13 |
|
|
|
| 14 |
|
|
2. MPI setup for 4 processors: |
| 15 |
|
|
a. with hand-written AD routines |
| 16 |
|
|
|
| 17 |
|
|
All header files (stuff in code_ad*) |
| 18 |
|
|
and input files (stuff in input_ad*) |
| 19 |
|
|
are kept in one directory. |
| 20 |
|
|
Depending on experiment, the relevant |
| 21 |
|
|
files are copied over from appropriate templates |
| 22 |
|
|
(see below). |
| 23 |
|
|
This helps ensuring that as little as possible |
| 24 |
|
|
changes between setups, and it it transparent |
| 25 |
|
|
exactly what has changed. |
