Welcome to the Techy Tuesdays segment! Each week here on Geek Alabama, Techy Tuesdays will feature something in the world of tech, tech news, or tech reviews. Everyone loves the latest in technology, and Techy Tuesdays will talk about all tech!
Modern DRAM is based on a brilliant design from IBM.
But, we’re still paying for a latency penalty that’s existed since the 60s!
In this video, I’m introducing my personal research project (Tailslayer) that immensely reduces p99.99 latency on traditional RAM!
By implementing a hedged read strategy taking advantage of (undocumented!) channel scrambling offsets, I’ve gotten as much as 15x reductions in tail latency.
The technique works across Intel, AMD, Graviton, DDR4, DDR5, x86, ARM, you name it.
