# Memtrace filters

Requires:

- Python

  * Pandas

  * Matplotlib

- OCaml

  * Memtrace

## irmin_index_memory.ml

Compares allocations from `Index` and `Irmin`

### Usage

Running `irmin-pack` benchmark with memtrace (in the irmin repo):

```shell

$ MEMTRACE=trace.ctf dune exec bench/irmin-pack/layers.exe

```

Now in the `memtrace-filters` repo:

Save image and data file:

```shell

$ dune exec ./filters/irmin_index_memory.exe ../irmin/trace.ctf > data

$ python3 plot/irmin_index.py -i data -o output.png

```

Save image to file (using pipe):

```shell

$ dune exec ./filters/irmin_index_memory.exe ../irmin/trace.ctf | python3 plot/irmin_index.py -o output.png

```

Display in window:

```shell

$ dune exec ./filters/irmin_index_memory.exe ../irmin/trace.ctf | python3 plot/irmin_index.py

```

Change title:

```shell

$ dune exec ./filters/irmin_index_memory.exe ../irmin/trace.ctf --title=$'my title with \n and \t will be displayed correctly'

```
