How does BLAS get such extreme performance?
...se fixed-size small-dimension operations (called kernels) are hardcoded in CPU-specific assembly code using several CPU features of their target:
SIMD-style instructions
Instruction Level Parallelism
Cache-awareness
Furthermore these kernels can be executed in parallel with respect to each other...
How to scale threads according to CPU cores?
...so I will have a look at this. And it can be scaled according to available cpu cores? Because I can't see that in you short examples. Best regards, Andreas

Why do x86-64 systems have only a 48 bit virtual address space?
...re not going to see a system which needs more than that any time soon.
So CPU manufacturers took a shortcut. They use an instruction set which allows a full 64-bit address space, but current CPUs just only use the lower 48 bits. The alternative was wasting transistors on handling a bigger address s...
