Programmable bootstrapping over GPU

This document details the GPU performance benchmarks of programmable bootstrapping and keyswitch operations using TFHE-rs.

{% hint style="info" %} All GPU benchmarks were launched on H100 GPUs, and rely on the multithreaded PBS algorithm with a grouping factor set to 4. {% endhint %}

P-fail: 2^{-64}

Reproducing TFHE-rs benchmarks

TFHE-rs benchmarks can be easily reproduced from the source.

The following example shows how to reproduce TFHE-rs benchmarks:

#PBS benchmarks:
make bench_pbs_gpu

#KS-PBS benchmarks:
make bench_ks_pbs_gpu
