Integer Operations over GPU
This document details the GPU performance benchmarks of homomorphic operations on integers using TFHE-rs.
{% hint style="info" %} All GPU benchmarks were launched on H100 GPUs, and rely on the multithreaded PBS algorithm. {% endhint %}
The cryptographic parameters PARAM_GPU_MULTI_BIT_GROUP_4_MESSAGE_2_CARRY_2_KS_PBS were used.
Pfail: 2^{-128}
8xH100-SXM5
Below come the results for the execution on eight H100 using SXM technology. 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:
