Holy cow, that's fast!! Is fast_float C++ getting 1.5GB/s as well?

[aldanor]

Might be also interesting - what happens if you compile it with target-cpu=native flag, does that change the performance at all?

[lemire]

target-cpu=native flag

I expect that this flag does not make sense. The aarch64 ISA has a few optional features but they are pretty much all related to crypto... so unless you are doing crypto, you won't see any difference. With x64, there is a wide range of ISA differences... hence the need to target specific architectures. It is possible that the Rust compiler could receive tuning specific to the Apple M1, but I would not expect that to ever be necessary. It is not like Rust is slow on the M1.

Holy cow, that's fast!! Is fast_float C++ getting 1.5GB/s as well?

Yes. I recommend you get one of these new laptop or whatever Apple comes up with in 2021. Their ARM processors are really killing it.

Feel free to reproduce these numbers in your README if you'd like. They are robust.

Feel free to reproduce these numbers in your README if you'd like. They are robust.

Would you mind re-running the benchmarks for M1 and Zeno on the latest master that I've just pushed? (there's also some new options in the bench tool there, like -o and all, for development), and lexical/lossy is dropped since it's basically the same timings as lexical non-lossy.

Something like this would be great (should probably make it all easier at some point):

cargo run --release -- file ext/canada.txt
cargo run --release -- file ext/mesh.txt
cargo run --release -- random uniform
cargo run --release -- random bigint_int_dot_int
cargo run --release -- random int_e_int
cargo run --release -- random one_over_rand32

And for the sake of completeness, it would be awesome to also have fastfloat_benchmark C++ timings is possible, to fill out the tables the same way.

Thanks a million!

[aldanor]

@lemire Thanks!

I've prepped a full script for you to run if you don't mind, builds and runs both fast-float-rust and fast_float on the same inputs (the random outputs are exported to files and then re-read by fast_float_benchmark):

#!/usr/bin/env sh

set -ex

git clone --recurse-submodules https://github.com/aldanor/fast-float-rust.git
cd fast-float-rust
mkdir -p scratch/data
cd extras/simple-bench
cargo run --release -- file ext/data/canada.txt
cargo run --release -- file ext/data/mesh.txt
cargo run --release -- random -f ../../scratch/data/uniform.txt uniform
cargo run --release -- random -f ../../scratch/data/iidi.txt bigint_int_dot_int
cargo run --release -- random -f ../../scratch/data/iei.txt int_e_int
cargo run --release -- random -f ../../scratch/data/rec32.txt one_over_rand32

cd ../../scratch
git clone --recurse-submodules https://github.com/lemire/simple_fastfloat_benchmark.git
cd simple_fastfloat_benchmark
mkdir -p build
cd build
cmake ..
make -j8
cd ..
./build/benchmarks/benchmark -f data/canada.txt
./build/benchmarks/benchmark -f data/mesh.txt
./build/benchmarks/benchmark -f ../data/uniform.txt
./build/benchmarks/benchmark -f ../data/iidi.txt
./build/benchmarks/benchmark -f ../data/iei.txt
./build/benchmarks/benchmark -f ../data/rec32.txt

Would you mind running this on both of your machines and posting the log? (this will produce the full set of numbers needed)

CMake Warning (dev) at build/_deps/doubleconversion-src/CMakeLists.txt:33 (option):
  Policy CMP0077 is not set: option() honors normal variables.  Run "cmake
  --help-policy CMP0077" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.

  For compatibility with older versions of CMake, option is clearing the
  normal variable 'BUILD_TESTING'.
This warning is for project developers.  Use -Wno-dev to suppress it.
