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 to
include function inputs and outputs, chaining functions, managing state,
accessing the distributed filesystem, dynamic linking, pthreads, OpenMP and MPI.
In our paper from USENIX ATC 20 we present
the initial Faasm design and evaluate it in the context of stateful serverless
functions.
In our paper from USENIX NSDI'25, GRANNY, we present the
design of the OpenMP and MPI runtimes, as well as new dynamic resource
management policies, all implemented in the faabric library.
Please see the full documentation for
more details on the code and architecture.
Quick start
Update submodules and activate the virtual environment:
Start a Faasm cluster locally using docker compose:
faasmctl deploy.compose
To compile, upload and invoke a C++ function using this local cluster you can
use the faasm/cpp container:
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
