Programming with Big Data -- Base Wrappers for Distributed Matrices
An interface to and extensions for the 'PBLAS' and 'ScaLAPACK'
numerical libraries. This enables R to utilize distributed linear algebra
for codes written in the 'SPMD' fashion. This interface is deliberately
low-level and mimics the style of the native libraries it wraps. For a much
higher level way of managing distributed matrices, see the 'pbdDMAT'
package.

pbdBASE is a set of bindings to and extensions for the distributed linear algebra libraries BLACS, PBLAS, and ScaLAPACK. The package is very low-level, and unless you are very familiar with these libraries (or even if you are...), you are instead recommended to see the pbdDMAT and pbdDEMO packages.
Installation
pbdBASE requires:
- A system installation of MPI
- R version 3.0.0 or higher
- The pbdSLAP and pbdMPI packages, as well as their dependencies.
Assuming you meet the system dependencies, you can install the stable version from CRAN using the usual install.packages():
install.package("pbdBASE")
The development version is maintained on GitHub:
remotes::install_github("RBigData/pbdBASE")
See the vignette for installation troubleshooting.
