Documentation:

• API reference (docs.rs)

Installation

Install OpenBLAS:

bash sudo apt-get install \ libopenblas-dev \ liblapacke-dev

Add this to your Cargo.toml:

toml [dependencies] russell_openblas = "*"

Number of threads

By default OpenBLAS will use all available threads, including Hyper-Threads that make the performance worse. Thus, it is best to set the following environment variable:

export OPENBLAS_NUM_THREADS=<real-core-count>

Furthermore, if working on a multi-threaded application, it is recommended to set:

export OPENBLAS_NUM_THREADS=1
