===Linear algebra libraries===
openSUSE uses reference BLAS and LAPACK implementations by default, but ATLAS is usually much faster. You can switch it by update-alternatives mechanism:
/usr/sbin/update-alternatives --config libblas.so.3
/usr/sbin/update-alternatives --config liblapack.so.3
Example:
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/lib64/libblas.so.3.4.2 50 auto mode
1 /usr/lib64/atlas/libsatlas.so.3 20 manual mode
2 /usr/lib64/atlas/libtatlas.so.3 20 manual mode
3 /usr/lib64/libblas.so.3.4.2 50 manual mode
===Image export and import===
GraphicsMagick++ library from openSUSE repositories was compiled with quantum depth 16 which limits reading and writing images to 16 bit. See more details on [[GraphicsMagick]] wiki page.
