This is my third report. |

Last week I pointed out the following objectives: |
| 4 |
* Interpret the user's input about the libraries to be tested. |
| 5 |
* Construct a test suite for BLAS. |
| 6 |
* Split from the script the test-dependent code. The script has to be |
| 7 |
general, while external modules will give information on how to |
| 8 |
install and test the implementation packages. |
| 9 |
* Make the portage interface better, possibly using the existing APIs. |
| 10 |
|
| 11 |
The first objective was recently achieved. Now the script can |
| 12 |
interpret a list of package atoms with special environment variables |
| 13 |
to be installed and processes the operations. It can be optimized in |
| 14 |
order to avoid multiple install of the same package with the same |
| 15 |
environment -- which will be an objective for the next week. |
| 16 |
|
| 17 |
The second and third objective had high priority. They have been |
| 18 |
achieved with satisfying results. The test suite is a modified copy of |
| 19 |
BTL from eigen development branch[1], which is now on my git |
| 20 |
overlay[2]. This has been adapted in order to only test the standard |
| 21 |
BLAS functions. Tests have been performed with blas-reference and |
| 22 |
eigen. The main script now reads from the command line argument list |
| 23 |
the name of the module to test -- can be blas, cblas, lapack,... -- |
| 24 |
and tries to load it. The module instructs the script on how to test |
| 25 |
an implementation. |
| 26 |
|
| 27 |
The fourth objective has been delayed untile the rest of the script is |
| 28 |
ready in order to change the implementation of the portage interface |
| 29 |
just once. |
| 30 |
|
| 31 |
Now that the BLAS test suite is ready, the two main objective for the |
| 32 |
next two weeks will be: |
| 33 |
* Enhancing the test suite |
| 34 |
* Generate a report with plots using gnuplot or matplotlib -- or both, |
| 35 |
depending on the installed tools |
| 36 |
* Support more libraries -- at least CBLAS and LAPACK |
| 37 |
* Remove commands and use subprocess instead. |
| 38 |
|
| 39 |
Modularity, scalability and maintainability are main priorities, and |
| 40 |
Python seems to be the right choice for that. |
