Add a bash script to run some benchmarks on AWS by jaja360 · Pull Request #43 · fastfloat/float_serialization_benchmark

This PR:

Adds scripts/aws_tests.bash which launches multiple AWS instances, runs the existing generate_multiple_tables.py on each of them, and pull back the generated tables locally.
Fixes an issue with the uniform_all generator (now called logscall_all).

- It always produced 'inf' because the range was greater than mt19937_64's limit - It makes more sense to use a logscale to better cover the range of possible floating values: uniform_all -> logspace_all

Great work.

My comments are non-blocking, just superficial comments.

Principally, this PR: - makes security_group and ssh_key configurable via env variables - generates them automatically if unspecified - adds some checks and comments - adds x86 instances.
