Blaze is an open-source, high-performance C++ math library for dense and sparse arithmetic. With its state-of-the-art Smart Expression Template implementation Blaze combines the elegance and ease of use of a domain-specific language with HPC-grade performance, making it one of the most intuitive and fastest C++ math libraries available. The Blaze library offers:
- high performance through the integration of BLAS libraries and manually tuned HPC math kernels
- vectorization by SSE, SSE2, SSE3, SSSE3, SSE4, AVX, AVX2, AVX-512, FMA, and SVML
- parallel execution by OpenMP, C++11 threads and Boost threads (Boost threads is disables in RcppBlaze3)
- the intuitive and easy to use API of a domain specific language
- unified arithmetic with dense and sparse vectors and matrices
- thoroughly tested matrix and vector arithmetic
- completely portable, high quality C++ source code
The RcppBlaze3 package includes the header files from the Blaze library with disabling some functionalities related to link to the thread and system libraries which make RcppBlaze3 be a header-only library. Therefore, users do not need to install Blaze and the dependency Boost. Blaze is licensed under the New (Revised) BSD license, while RcppBlaze3 (the 'Rcpp' bindings/bridge to Blaze) is licensed under the GNU GPL version 2 or later, as is the rest of Rcpp.
RcppBlaze3 will follow the latest version of Blaze, If you are looking for a C++98 compatible 'Blaze', you might consider using RcppBlaze.
You can install:
-
the latest development version from github with
install.packages("devtools") devtools::install_github("ChingChuan-Chen/RcppBlaze3")
If you encounter a bug, please file a reproducible example on github.
