On Odroid-XU3 with 4 "big" Cortex-A15 cores and 4 "LITTLE" Cortex-A7 cores, OpenBLAS configures itself with the maximum number of threads equal to the total number of cores, i.e. 8 (-DMAX_CPU_NUMBER=8). I'd say it's probably better to configure OpenBLAS to limit the maximum threads to the number of big cores only. Any thoughts?
