First please see, for example, this ARM CPU

L1 cache per 1 core.
L2 cache per 2 cores.
L3 cache for all (8) cores.
It is critical for multithread BLAS (and D BLAS is going to be
the best BLAS ever) to estimate that L2 cache is per 2 cores.
In the same time it is impossible to collect information about
each ARM CPU configuration. Any hope to receive this information
at runtime?
Best regards,
Ilya
