Integer

This document details the HPU performance benchmarks of homomorphic operations on integers using TFHE-rs.

All HPU benchmarks were launched on AMD Alveo v80 FPGAs.

The cryptographic parameters HPU_PARAM_MESSAGE_2_CARRY_2_KS32_PBS_TUNIFORM_2M64 were used.

Below are the results for the execution on a single Alveo v80 board. The following table shows the performance when the inputs of the benchmarked operation are encrypted:

The following table shows the performance when the left input of the benchmarked operation is encrypted and the other is a clear scalar of the same size:

Reproducing TFHE-rs benchmarks

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

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