# Faasm [](https://github.com/faasm/faasm/actions) [](https://github.com/faasm/faasm/blob/main/LICENSE.md) [](https://github.com/faasm/faasm/releases/) [](https://github.com/faasm/faasm/graphs/contributors/) [](https://codecov.io/gh/faasm/faasm)
Faasm is a high-performance stateful serverless runtime.
Faasm provides multi-tenant isolation, yet allows functions to share regions of
memory. These shared memory regions give low-latency concurrent access to data,
and are synchronised globally to support large-scale parallelism across multiple
hosts.
Faasm combines software fault isolation from WebAssembly with standard Linux
tooling, to provide security and resource isolation at low cost. Faasm runs
functions side-by-side as threads of a single runtime process, with low
overheads and fast boot times.
Faasm defines a custom host interface that extends [WASI](https://wasi.dev/) to
include function inputs and outputs, chaining functions, managing state,
accessing the distributed filesystem, dynamic linking, pthreads, OpenMP and MPI.
Our paper from Usenix ATC '20 on Faasm can be found
[here](https://www.usenix.org/conference/atc20/presentation/shillaker).
Please see the [full documentation](https://faasm.readthedocs.io/en/latest/) for
more details on the code and architecture.
## Quick start
Update submodules and activate the virtual environment:
```bash
git submodule update --init --recursive
source ./bin/workon.sh
```
Start a Faasm cluster locally using `docker compose`:
```bash
faasmctl deploy.compose
```
To compile, upload and invoke a C++ function using this local cluster you can
use the [faasm/cpp](https://github.com/faasm/cpp) container:
```bash
faasmctl cli.cpp
# Compile the demo function
inv func demo hello
# Upload the demo "hello" function
inv func.upload demo hello
# Invoke the function
inv func.invoke demo hello
```
For more information on next steps you can look at the [getting started
docs](https://faasm.readthedocs.io/en/latest/source/getting_started.html)
