I'm using 64bit atomics at work, are you on an old version of cuda or are some operations only supported on 32bit?
- tspeterkim 2y agoI misspoke. (got confused with the key limit in my link above) Atomics work up to 128-bits (https://docs.nvidia.com/cuda/cuda-c-programming-guide/#atomic-functions https://docs.nvidia.com/cuda/cuda-c-programming-guide/#atomi...). Regardless, it's still less than 100 bytes, which is the max length of city strings.
