and take on NVLink and NVSwitch head on and create a more streamlined and different set of ASICs and protocols and not just kluge something together that would sort of work. (Like the CXL memory protocol over PCI-Express, which has some serious limitations in terms of bandwidth and radix.)...
Moreover, for 64-bit integer keys it is at least 63% and on average 2 times faster than the highly optimized GPU Thrust radix sort that directly manipulates the binary representation of keys. Our implementation is robust to different distributions and entropy levels of keys and scales almost ...
