Concerto: Transaction-Parallel EVM

How to run

First, generate a serialized cachedb for in memory reads

cargo run --example load_db --features="example_utils"

Then, to execute the test, run the following:

cargo run --example parallel --features="example_utils"

To compare execution of sequential vs parallel for correctness:

cargo run --example compare --features="example_utils"

To test performance, add the --release flag like such

cargo run --example compare --features="example_utils" --release

Profiling:

CARGO_PROFILE_RELEASE_DEBUG=true cargo flamegraph --root --release --example simple --features "example_utils"

Performance

Compared to a single-threaded REVM instance, Concerto performs 4x faster when running with 6 threads
