In the readme file, you mentioned multi-core parallel and ARM big.LITTLE cpu sheduling optimization.
It seems that the multi-core parallelism is implemented by OPENMP, but what about the bit.LITTLE cpu sheduling? Can you please kindly explain how it's implemented? Thank you in advance.

we set openmp thread affinity to the specified big or LITTLE cores
you may find implementation details in src/cpu.cpp
