Microsoft R Open

Microsoft R Open (MRO) was an enhanced, open-source distribution of R that provided massive performance boosts. However, Microsoft officially retired MRO.

Even though the package itself is retired, the core technology that gave MRO its speed—multi-threaded Basic Linear Algebra Subprograms (BLAS)—is still highly relevant and easy to implement in standard CRAN R today. 🚀 Why Microsoft R Open Was Faster

Standard R is single-threaded and relies on a reference BLAS library. It processes tasks sequentially on a single CPU core, leaving the rest of your system idle.

Microsoft R Open solved this bottleneck by integrating the Intel Math Kernel Library (MKL). Fast R code – DARTISTICS!
