While we didn't use `rustix` directly, it was an indirect dependency of `clap` (`clap` -> `clap_builder` -> `anstream` -> `is-terminal` -> `rustix`). Now it is no longer an indirect dependency, as `anstream` no longer depends on `is-terminal`.
ftmemsim
A tiered-memory simulator.
Usage
To use this library, first clone it:
git clone https://github.com/Zenithsiz/ftmemsim
(If you need to generate traces, also clone the submodules with --recurse-submodules).
After this, you can check run-tracer.sh for an example on how to trace a program. You'll need to compile the valgrind fork in extern/ftmemsim-valgrind. Follow the instructions on it's README for building.
You'll also need the parse-valgrind rust tool. You can use the following to build it:
cargo build --release --package "parse-valgrind"
You can now run the simulator with these traces. Look in the run.sh file for examples, but it boils down to running the simulator itself:
cargo run --release --package ftmemsim -- \
--config <config-file> \
<trace-file> \
--output <output-file>
Finally you can use ftmemsim-graphs to generate some graphs from it's output. See ./ftmemsim-graphs --help for a list of all the graphs. You can run, for example, the following:
cargo run --release --package ftmemsim-graphs -- \
page-migrations \
<simulator-output-file> \
--config <config-file> \
--output <output-image>
