Dear all, |
2 |
|
3 |
After some years with the official blas and lapack libraries from atlas |
4 |
several weeks ago these packages were discontinued in the official portage |
5 |
tree, being replaced by the science overlay. I've tried to get the same |
6 |
functionality than before, but with no luck. |
7 |
|
8 |
I used to run sci-mathematics/jags compiled against the atlas-threaded |
9 |
libraries, and when simulating more than one chain all processors were used |
10 |
in parallel. But now, with the current sci-libs/atlas libraries this is not |
11 |
the case anymore. |
12 |
|
13 |
I have also tried to link jags against openblas, but without luck as well. |
14 |
|
15 |
I have also tried to compile it against mkl using openmp and even compile |
16 |
jags without using the official ebuild. |
17 |
|
18 |
So my questions are: |
19 |
|
20 |
- Is there a way to check that atlas is using multithreaded capacities, |
21 |
besides checking the libraries towards which it is compiled? |
22 |
|
23 |
- What has atlas changed between the last unstable ebuild from the |
24 |
official portage tree and the last unstable ebuild from the science |
25 |
overlay? |
26 |
|
27 |
- Any guess on how I can make use of multithreading in jags in gentoo? |
28 |

Many thanks. |
