# cu_intercept

A small preload utility to intercept CUDA memory managment.

---

## Compile 

```

cmake -B build .

cd build

make

```

## Usage

```

LD_PRELOAD= 

```

## Outputs

In the path where you are running the programm with the LD_PRELOAD you wil find files named `output..txt` where `` is replace by the pid of your programm.

They contain the amount of memory allocated by the programm at every time of allocations.

you can read them with python like so:

```py

import numpy as np

import matplotlib.pyplot as plt

out = np.loadtxt("output.324547.txt")

plt.plot(out[:,0],out[:,1])

plt.xlabel("time [s]")

plt.ylabel("memory [byte]")

plt.show()

```
