Gradient Boosted Trees: Two Types of Numbers, Two Types of Failure

Quantising a GBT model is not the same as quantising a neural network. A neural network weight rounded slightly produces a small, continuous error. A GBT threshold rounded slightly can send an input down the wrong branch, producing a catastrophic error, greater than 100 % on real benchmark data. The correct approach is to quantise the input data before training and compute leaf bit-widths analytically from the trained ensemble.

Gradient Boosted Tree Inference is not what you think it is

GBT inference speed is not limited by arithmetic; it is limited by memory access. Two structural choices made at training time, tree depth and ensemble-to-core mapping, determine whether latency is bounded or openended. These are not tuning knobs; they are architectural decisions that should be set before deployment, not discovered in production.

Datacenter Networks

This week, the SmartNIC Summi takes place in San Jose, California. It brings together industry experts, users and vendors of SmartNICs, Data Processing Units (DPUs) and Infrastructure Processing Units (IPUs). The common thread among these technologies is that they allow us to move data processing tasks into the NIC in addition to basic network functions. But why are network developers doing this in the first place? And why are they doing it now?
