How do CUDA blocks/warps/threads map onto CUDA cores?
...8 cores.
2'. There is a big difference between 8 blocks of 48 threads and 64 blocks of 6 threads. Let's assume that your kernel has no divergence and each thread executes 10 instructions.
8 blocks with 48 threads = 16 warps * 10 instructions = 160 instructions
64 blocks with 6 threads ...

...egers up to the length of the significand, and as per ECMA standard it's a 64bit float. So it can exactly represent integers up to 2^52

What is BSON and exactly how is it different from JSON?
...o be fast to encode and decode. For example, integers are stored as 32 (or 64) bit integers, so they don't need to be parsed to and from text. This uses more space than JSON for small integers, but is much faster to parse.
In addition to compactness, BSON adds additional data types unavailable ...
