Prefix sums at tens of gigabytes per second with ARM NEON

Suppose that you have a record of your sales per day. You might want to get a running record where, for each day, you are told how many sales you have made since the start of the year. day sales per day running sales 1 10$ 10 $ 2 15$ 25 $ 3 5$ 30 … Continue reading Prefix sums at tens of gigabytes per second with ARM NEON
