Benchmarks

Due to their nature, homomorphic operations are naturally slower than their clear equivalent. Some timings are exposed for basic operations. For completeness, benchmarks for other libraries are also given.

Boolean

This measures the execution time of a single binary Boolean gate.

tfhe-rs::boolean.

tfhe-lib.

OpenFHE.

Integer

This measures the execution time for some operation sets of tfhe-rs::integer.

All timings are related to parallelized Radix-based integer operations, where each block is encrypted using the default parameters (i.e., PARAM_MESSAGE_2_CARRY_2, more information about parameters can be found here). To ensure predictable timings, the operation flavor is the default one: the carry is propagated if needed. The operation costs could be reduced by using unchecked, checked, or smart.

Shortint

This measures the execution time for some operations using various parameter sets of tfhe-rs::shortint.

This uses the Concrete FFT + AVX-512 configuration.

Next, the timings for the operation flavor default are given. This flavor ensures predictable timings of an operation along the entire circuit by clearing the carry space after each operation.

How to reproduce benchmarks

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

#Boolean benchmarks:
make bench_boolean

#Integer benchmarks:
make bench_integer

#Shortint benchmarks:
make bench_shortint

If the host machine supports AVX-512, then the argument `AVX512_SUPPORT=ON' should be added, e.g.:

#Integer benchmarks:
make AVX512_SUPPORT=ON bench_integer
