bqskit-qfactor-jax 0.0.1

QFactor GPU implementation in BQSKit using JAX

QFactor implementation on GPUs using JAX

bqskit-qfactor-jax is a Python package that implements circuit instantiation with QFactor on GPUs to accelerate BQSKit. It uses JAX as an abstraction layer of the GPUs, seamlessly utilizing JIT compilation and GPU parallelism.

Installation

bqskit-qfactor-jax is available for Python 3.8+ on Linux.

First, install JAX with GPU support, you may refer to JAX's installation instructions.

Next, install this package with pip:

pip install bqskit-qfactor-jax

Running bqskit-qfactor-jax

Please set the environment variable XLA_PYTHON_CLIENT_PREALLOCATE=False when using this package.

Please take a look at the examples to see some basic usage.

When using several workers on the same GPU, we recommend using Nvidia's MPS. You may initiate it using the command line

nvidia-cuda-mps-control -d

You can disable it by running this command line:

echo quit | nvidia-cuda-mps-control
